Super capacitor, may be to replace the lithium-ion battery

Category: Uncategorized — admin @ 9:06 pm

So far the industry has decided that lithium-ion batteries rechargeable laptop battery  for electric cars is still the primary means of energy reserves, but now, several companies have begun to consider using a super capacitor (ultracapacitor) lithium -ion battery products as additional sound equipment.

South Korea will be an electronics company Neescap Tuesday claimed that 9 million dollars will be invested to develop its systems for power transmission and consumer electronics with super capacitor (ultracapacitor) the ability of the product. In the United States and the ability to design and manufacture of super-electrolytic capacitors and materials necessary for the company he GrapheneEnergy, EnerG2 and Ioxus 3. dell inspiron 1521 battery,dell inspiron 1525 battery  Another one business EEStor by VCs KleinerPerkinsCaufield & Byers as the background, now the company has signed an electric car company Zenn super-contract to supply capacitor.

The more traditional batteries, ultracapacitors can store electricity are not numerous. So at home Rechargeable (plug-in) for electric vehicles, such capacity can serve as devices of engine power alone, but must be linked with the fuel cell use. On the other hand, the supercapacitor is also equipped with quick energy output diarrhea stored in capacity.  hp pavilion dv2000 battery In addition, the capacitor charging time is very short, only takes a few seconds or minutes of time will be able to complete the charge, but charge several times the performance there will not be reduced.

The consumer electronics capacitor products have been used in digital cameras and other occasions, so need momentary flash high-energy input of the device provides the energy supply. According to experts, super critical issues for the future is how to increase the range of voltage capacitor so it can in high voltage environment.

According to engineers Ioxus said, the supercapacitor energy is environmentally friendly, a good supplement can make batteries, fuel cells, solar or wind energy, food would be more perfect. At the same time, the capacitor used in the production of such materials are also very environmentally friendly, Some prices are also more easily accepted.

Super capacitor technology, the orientation of future development:

Massachusetts Institute of Technology engineers in computer electronics JoelSchindall said that in the coming years, the super capacitor storage energy will be a qualitative leap. toshiba pa3399u-1brs battery  The current rate products super capacitor discharge is 10 times that of traditional batteries, while the storage of energy in the volume of the same only the latter under the condition of 5%.

He says: “charge super-capacitors and unloading of the prevalence of some great occasion, as Brake Energy Recovery System-brake type (ie, five series of F1 CCAV all day nagging system host Coles), This ability is very easy to use. Of course, this product is currently not a large scale to replace the batteries. ”

Over the past five years, Schindall led the research team studied the super capacitor in the storage component of energy - raw porous carbon replaced by another matrix material of conductive carbon nanotubes + storage components energy. Earlier this year, they were prepared for FastCap companies, for the commercialization of research results.

Schindall says the super capacitor storage energy of the product will eventually reach about 25% of the battery. Massachusetts Institute of Technology developed at present out of nano-materials,  ibm fru 92p1141 battery storage of energy has reached twice the level of carbon materials. But the months that followed, he led the research team will be showing the kind of capacity energy storage is five times more activated carbon products.

Urine Bianshen fuel cell

Category: Uncategorized — admin @ 8:30 pm

U.S. scientists have recently used a new technology, so that urine can electric cars, appliances and other equipment can also provide energy.

Scientists using nickel electrodes can be extracted from the urine of high hydrogen and cheap, while hydrogen can also be an automotive fuel or used to manufacture fuel batteries . It is reported that cow’s urine for 19 families to provide sufficient energy for hot water.

Urine, or technology of hydrogen energy is essentially the use of technology. Because the chemical composition of urine contains hydrogen, hydrogen gas through the urine was compared to less use of electricity through water to get a lot of hydrogen. Urea molecules are the main component of urine, which contains four atoms of hydrogen and two nitrogen atoms. Will be a special nickel electrodes inserted into the container of urine to pass on the message stream will release hydrogen.

Researchers have invented a urine fuel battery  prototype smaller, could only produce 500 milliwatts of electricity. Their next goal is to achieve industrial production and widespread use. It is estimated that for every liter of urine is theoretically possible to ensure the urine cell vehicles fuel duration 90 miles a refrigerator-sized fuel cell can produce urine of 1000 watts of power.

Chemists said that a chicken farm produce electricity through the urine enough to maintain its normal operation. It is reported that in the United States for livestock farms are required to excrete waste treatment, this change, the urine of new technologies for clean energy will certainly be able to get the double benefit effect .

Lithium batteries for electric cars overheat with disastrous consequences

Category: Uncategorized — admin @ 8:26 pm

Short-circuit or internal damage occurs may lead to a variety of the latest generation of lithium-ion batteries overheating phenomenon, prevalent in the electronics of this issue of the electric car could be disastrous.

It seems that the summer of 2009 is considered a milestone in the green car.

In July, located in Tokyo, Japan, Mitsubishi Motors has announced its new total of U.S. $ 48,000 electric micro-car i-MiEV to go on sale this month, an official with the market already Fuji Heavy Industries, Nissan, and BYD Electric’s automotive products to the competition.

However, even if car manufacturers are competing in the region before they show more edge and achieve a hobby, pleasant attitude of the electric car, but some technical experts are always a variety of concerns.

Before that, they pay more attention to battery life, and the mileage life recently, technical experts have also reported a series of short-circuits or internal damage occurs may lead to the latest generation of lithium - Ion batteries overheating phenomenon.

In mobile phones, laptops and other electronic products used in the battery, each battery 500-10000000 be a case of a similar situation - which means that the risk of fire.

Laptop battery is usually composed of six batteries, battery pack electric vehicle, the ability to more - probably at least 75 or 80 batteries, which is the subtext underlying - that the speed on the highway electric car , each of 60000, perhaps we will have at least one problem.

“Even if it is a low probability event, but the event, the consequences would be catastrophic.” Accelerating the amount of U.S. manufacturer well-known expert of the battery thermal equipment Tiax Brian Barnett (BrianBarnett) warned.

The problem is that the fire caused by the battery, their severity will be compared with conventional fuels at a greater risk of a burning car do?

“A big danger is that if a battery troubles, this problem will be” President transmitted to the battery and other batteries, “the United States AAB (AdvancedAutomotiveBatteries) Meinahaimu Anderman (MenahemAnderman) the concern that because the battery technology is still in its infancy, it is difficult to quantify the risk is not negligible.

Even if the battery problems will not be like a normal car on fire the fire spread so quickly, but it will be a little bit of land erosion, a key component of the organization until that He wants to see accidents.

The experts noted that such shortcomings do not appear immediately in the battery. But the thousands of electric cars are likely to encounter in a road accident in movement of the battery, even if the occupant was not injured, vehicle manufacturers have also received a great blow.

In 2006, because of problems with Sony VAIO notebook battery recall, a loss of 258 million euros. In electric vehicles, the battery costs represent 50% of the total cost, if there are problems, the loss is more painful than notebook computers.

Of course, automakers are prepared to insist that their cars are safe.

Nissan said they coat the battery uses a special material, low thermal conductivity of these materials, you can minimize the risk of overheating batteries. The leading Chinese battery technology experts has insisted that its battery iron BYD is perfectly safe.

Mitsubishi i-MiEV battery is not easy bending deformation of the rigid frame to protect them, then added a layer of impact outside the cage of the chip to control the load and continue to monitor each and condition battery.

Mitsubishi Motors President, Nishioka Bridge (OsamuMasuko) believes that these measures have greatly reduced the risks involved by the battery. In his last two years has been using a red and white i-MiEV, a full-time driver to drive for him, it seems that there has not been a big problem.

To ensure safety, the Japanese automakers to conduct tests on the active stack. For example, Nissan and Mitsubishi engineers and, in extreme hot and cold, keep the battery charge and discharge, and simulate a variety of conditions of cell damage.

However, technical experts believe that these measures can not guarantee the elimination of lost potential dangers.

“Unless you put the battery installed in the car and someone opened a few years,” the study of batteries Tokyo market analyst firm Fuji SeijiEzaki economic groups, said: “If you do not l ‘review current practice, you do not really know how to use the battery as well as in the real battery status appears to use a kind of situation. “

Bio-technology to solve waste batteries, heavy metal pollution

Category: Uncategorized — admin @ 10:14 pm

In recent years, the pollution problem of used batteries at home and abroad increasingly concerned about the waste contains large quantities of heavy metals in the environment of the battery after the soil, and water is a serious threat to humanity itself. Due to less acid consumption, handling, low cost heavy metals leaching high operating temperature and pressure, etc., some researchers are trying to use bio-leaching technology, rechargeable laptop battery remove the battery from waste and recycling of toxic heavy metals, a more systematic study of China specialists, bio-leaching waste filtered in more nickel in nickel-cadmium batteries, cadmium, cobalt is feasible. batteries oxides and hydroxides of heavy metals exist mainly in the form, rather than the form of sulphides, batteries of bioleaching is required along with a large number of prototype materials, such as sulfur and ferrous ion, so that the bio-leaching mechanism may be related to ore, sludge, fly ash and soil leaching of sulphide mechanism is very different, but the batteries for the mechanism of bioleaching has been rarely reported.

      Lithium-ion battery is currently the largest amount of secondary batteries, which contain cobalt in the market in recent years has reached 75 ~ 90 yuan / ton, the dissolution of cobalt and recycling of used lithium-ion batteries have been treated for topics, while cobalt bioleaching and release of solvents also recently been the concern of scholars home and abroad. published in “Science Bulletin No. 23 of 2008,” Lithium-ion battery scrap precious metals bioleaching mechanism of cobalt “The paper reported the lithium-ion battery scrap cobalt bio-leaching mechanism to reveal the impact type energy matrix cobalt leaching efficiency of underlying causes.

      Bioleaching refers to the use of certain micro-organisms or their metabolic products of oxidation, reduction, complexation, adsorption, or dissolution, the solid-phase extraction of some of the insoluble components of a technology. In recent years, bioleaching technology goods in low-metal minerals, heavy metals remediation of contaminated soils, sewage sludge and hazardous fly ash removal of heavy metals detoxification and many other aspects to be studied in depth. Bio-leaching technology is currently the most widely used is the Thiobacillus ferrooxidans and Thiobacillus ferrooxidans, the primary mechanism is the use of these two types of acidophilic Thiobacillus bio-oxidation and low pH environment will result type intractable heavy metals that can be dissolved state. The research group has studied the bacterium Thiobacillus ferrooxidans and composition of mixed strains used lithium-ion batteries leaching.

      In the ore, sludge, fly ash and soil solid phase, heavy metals, mainly in the form of sulfur is generally accepted that their leaching leaching mechanisms involving direct and indirect mechanisms. Thiobacillus acidophilus direct mechanism is through the cell and some Bennett direct sulfur oxidation enzyme system of mines in a soluble sulfate, dell latitude d610 battery,dell latitude d620 battery  indirect mechanism is mainly the use of Thiobacillus ferrooxidans metabolites - the high sulfuric acid for iron-oxidizing sulfides metal sulfates.

      The results show that strains mixed cobalt leaching efficiency above 90%, but also with a mixture of sulfur and pyrite in the matrix of energy, cobalt leaching efficiency than a single atom sulfur pyrite or only where a substantial increase in the energy matrix. also showed that lithium-ion fragments of the dissolution of cobalt is entirely attributed to the indirect mechanism of bioleaching has no direct mechanism.

Temperatures dropped batteries “chilly” insulation products and technical personnel Weapon

Category: Uncategorized — admin @ 10:05 pm

Who will take the cold, electrical appliances are also afraid of the cold? In winter, low temperatures, some people are usually used in electronic products has emerged as unusual electric cars more and more without riding, cellphone, MP3, portable computers require refills frequent. Maintenance personnel have said that the battery laptop battery rechargeable  is also a cold-blooded “in.

      Mr. Zhang, the batteries of electric vehicles only new public will soon feel the battery without having recently used. Mr. Zhang said that the car had a single battery charge, to work more than sufficient to run four times, but this time, but the clear impression that the car is loose.

      Electric point of vehicle maintenance for the technical staff, said: “Recently, due to lack of battery power coming to extensive public consultation, most of them reflect their own without using the car battery, and some even suspect that the renovation of old batteries to buy. In fact, winter electric capacity reduction of the car battery is a normal phenomenon. ”

      The technical staff has explained that “electric cars are mainly used in lead acid batteries. This is the best working environment for the battery temperature is 15 ℃ - 40 ℃. Below this temperature, the storage capacity of the battery will be reduced. The lowest temperature of power The most obvious decrease in winter low temperature, dell y9943 battery,dell fk890 battery electric vehicles would also reduce the travel distance, until the temperature rise will be restored. Today, batteries electric vehicle device isolation has not yet opened to universal coverage. To ensure the normal use of electric vehicles, the simplest approach is to charge users in a timely manner. ”

      In fact, the winter, “cold” and lead acid batteries used in electric vehicles, cell phones, MP3, laptop, lithium batteries are also used in “cold blood.”

      Qin mobile phone before the public two days to recharge a battery, and now you have to recharge every day and sometimes can not be recharged inside. In this regard, the maintenance staff of batteries, said: “Currently, most mobile phones and laptops use lithium-ion batteries. In a time of low temperatures, lithium batteries will be a sharp drop in activity. This has led to lithium batteries have been locked, power is not only put out so can not be recharged inside. ”

      Since the battery is too afraid of cold, for normal use, you can give them, “Paul the heat.” Maintenance staff, said: “When it occurs, the user is easy to damage if the force charge the battery. hp f4812a battery To ensure the normal operation of electronic products, mobile users can be mobile, MP3 small electronic products such as cash, with body temperature to maintain the temperature lithium batteries. as a laptop as increased size of electronic products, it can be removed the battery, the battery placed in warmer places, hitherto responsible when using it. “

Li-ion battery electrolyte Industry Market Situation and Development

Category: Uncategorized — admin @ 1:59 am

Science and Technology Minister Wan Gang, China Green Energy Automotive Development Summit Forum, new energy vehicles in China are given development goals by 2012, China had 10% the production car will make energy conservation and new energy vehicles. Do not the same projections, in 2008, Chinese production of automobiles is approximately 9.3 million euros, while the annual production in 2012 rose to 10 million euros, rechargeable laptop battery  the new energy vehicles will reach an annual production of 1 million scale.
Investment Advisor in the automotive industry, said analyst Li Sheng-mao, according to each new hybrid energy costs 6 million car batteries lithium iron phosphate cathode material 52 kg, 41 kg of anode material The electrolyte 40 Calculation kg. 1 million hybrid vehicles will lead the 52,000 tons cathode material, anode material for 41,000 tons, 40,000 tons of electrolyte needs. For manufacturers of household batteries, it would be a gross production value of 60 billion yuan of big cake.

According to the industrial chain, battery power can be divided in the manufacture of battery and battery materials, finished goods, the manufacture of two types of companies, batteries can be divided into electrode (positive / negative) materials, separator and electrolyte.

Li Sheng-mao said electrolyte affect the performance of lithium batteries is another important material, since it represents the cost of lithium batteries by about 13% gross margin close to 38%. Battery manufacturers current internal supporting electrolyte has been performed mainly at national level. However, the electrolytes, the basic technology is still controlled by the hands of developed countries, the current of the lithium electrolyte urgent need to solve the most critical element of the electrolyte lithium hexafluorophosphate (LiPF 6) production synthesis problems. Only technological advances, China’s energy industry chain automobile may be close to perfection.

The main raw materials for lithium hexafluorophosphate electrolyte, which represents about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, the price of 40 yuan / ton,  dell gd761 battery gross margin reached 75% , domestic enterprises are not capable of producing. Currently on the market has been Kanto electrochemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly.

It is understood that the lithium current global electrolyte balance between supply and demand, mainly by the stock market for lithium batteries, the future market to see the additional market power lithium battery, vehicle Electrical especially after the rise will bring the explosive growth of the electrolyte. Experts said that the electrolyte remains within 3-5 years after the industry sunrise.

Turning to the outlook for energy batteries new motor, with representation from industry, the requirements of the lithium electrolyte of relatively high, but rarely use. For example, a cell phone battery with only 3 grams, the weight of the small, 2,000 tons of electrolyte can be produced 600 million cell phone batteries. Vehicle battery, the power is not the case, and a car is needed for 40 kg!

Currently engaged in the production of lithium electrolyte mainly Shanshangufen companies, Huarong Chemical Co., Electronic Zhuhai race Wei, Tianjin, Taurus, Golden Shantou, Guangzhou and a messenger from heaven, and so more than 10.hp pavilion dv2000 battery  Among them, Huarong Chemical Co., Zhuhai race frame positioning electronic high-end market, other companies can only do low-end market.

Category: Uncategorized — admin @ 2:52 am

Antifreeze: For the region of Shanghai, in winter, winter antifreeze type need not be replaced, but if the North to be wary. In addition, some older cars are often phenomenon drip of antifreeze and many people will pay in ordinary water to reconstitute the freeze in the winter cold conditions if there is violence, it is very may be hidden, preferably in winter to maintain, to solve the problem of leaks and replace antifreeze.
Wipers: After a summer of sun exposure, vehicle rubber wiper windshield may have already disappeared. Must be replaced, usually wiper rubber once a year in need of replacement. In addition, it is recommended to choose towel bone. Boneless wiper was the first choice for premium cars, and now general models can also be arbitrarily replaced. Windshield Bone does not replace the arm wiper, only to replace the wiper blades, ice can be.
Car maintenance Winter Sanda Jian: oil, water, wheel tire. Finish: Winter damage to the finish no less than in summer, even if the sun is no longer the strong, but the ultraviolet light was still alive, a long-term exposure to paint fade and produce small cracks. Polish, varnish sealing, coating electrophoresis, are resistant to adverse weather conditions caused by damage to the measures of arrival. Friends owners can choose according to the actual situation in a different way to maintenance.
