According CCPIT Electronics & Information Industry Sub report, while crude oil exhausted expectations electric car, hope it can to protect the environment, to a new dynamic. Experiments show that electric vehicles can meet the expectations of people, and find the perfect cell program has been the target of researchers. toshiba PA3478U-1BRS toshiba PA3534U-1BRS
If you can really achieve by 2030 the development of the German state, the scene described electric vehicle – Germany has five million electric cars on the street driving – let us look back. In the vehicle internal combustion engine was born 30 years ago, electric vehicles already on the road, and create a considerable speed record: 1899 Belgium Camille Jenatzy driving their own vehicles manufactured, faster than 100 km / hour. Turn of the century, power has emerged from the taxi fleet in New York. However, because of the failure to continue to provide energy to the program of the battery electric vehicle, its development has long stagnated.
Compared to internal combustion engine to power the engine power advantages are obvious: speed, fast, power up to 3-4 once, driving noise, and does not require any driver installation. However, the shortcomings of electric vehicles are also an important point is that power always be consumed quickly. toshiba PA3535U-1BRS toshiba PA3591U-1BRS
From a global perspective, researchers have considered and developers focus on batteries, battery technology lithium-ion represents the current level of research. The early nineties, Sony produced the first small lithium-ion batteries due to its high performance, long life, charging time and short, rapidly in smaller devices like mobile phones, laptops and model aircraft has received application. In the automotive field, but no one wants to use the original battery lithium ion, lithium as electrode material not only causes the voltage is too high, and very easy to do with reactions to other elements.
In the laptop, even light damage batteries and only to extremely high temperatures and under high voltage charge would lead to the loss of the battery cells in the air, causing the computer caught fire. However, the German state of Baden Fraunhofer Institute for Chemical Technology Pfinztal battery researcher Jens Tübke said: “The car was completely different.” Motor vehicle battery to store much energy, they may even turn into a bomb. In the laboratory, and factories, single voltage below 3.6 volts, it will change once the short-circuit and thermal expansion, the battery has finished a batch of a single voltage, in such great conditions energy density, even light touch, the consequences would be unthinkable. toshiba PA3465U-1BRS toshiba PA3480U-1BRS
For the user, it is important to recognize that what is most useful in terms of their own.
Safety: the Fraunhofer Institute for Silicate Würzburg, researcher in the Department of Kai-Christian M? Ller tried polymers non-combustible, flammable liquids to replace the battery, but the jelly-plastic electrodes will impact load time extension can not be performed excellently.
Saxon joint venture Li-Tec has tried other ways to address these security issues. Generally, the battery manufacturers are using a thin plastic membrane that separates the two electrodes, but when the temperature reaches 140 degrees Celsius, they will be like the bottom plate of plastic melt as easily cause short circuit. Li-Tec ceramic particles used as a covering membrane that can withstand 700 degrees Celsius, but the battery is reduced. On the other hand say that the battery charge and discharge shall not be abandoned after 4000, which requires daily recharging electric cars is very important. Li-Tec Corporation will launch next year of this car is safe and durable batteries. toshiba NB100 battery toshiba NB200 battery
Sustainability: Society Lithiumtitanat can be done with great battery charge and discharge at least 15,000 times (2000 times the operator excellent). The battery life of up to ten years in the medical equipment in the well of the application, the medical technology of great value.
Discharge capacity: If you want to store in a small space more energy, can add Iwo electrode. In theory, Iwo to three times more than conventional polymer electrode of lithium-ion batteries. In the laboratory, this approach may seem bright future, but only charge and discharge of 20-40 times, after an almost unusable.
Fast Charge: If you want fast charge, the iron phosphate of electrode materials for good results. This mobile phone battery can be less than 20 seconds is charged – at least in the laboratory is the case, but require considerable power. sony vgp-bps10a/b sony vgp-bps10b
Safety car batteries, discharge capacity and sustainability are closely related, the consumer, rose, and battery manufacturers in a quandary, one aspect of the increase mainly to the cost of sacrificing other aspects . Pfinztal Tübke battery expert said: “Fortunately, the system lithium-ion there is still much to do.”
For battery-electric vehicle using gasoline or diesel-class transportation driving range, and the safe and economic for the moment, or can not be reached, the metal-air battery as well. In the metal-air battery, oxygen from the air was as lithium reagents. IBM Fellow Chandrasekhar Narayan said: “It’s like a combustion engine battery. Now the smoke in the air at the vehicle, the combustion of gasoline, the air will be used in the electrochemical reaction future. “IBM hopes to use this way to the electric vehicle mileage of 800 kilometers – more that Lithium-ion batteries present beyond 10 times. IBM expected to produce a first sample five years, while other researchers should be extremely cautious in this research program requires a lot of time in decades. sony vgp-bps10 sony vgp-bps10a
Finally, we discuss an old program that was originally designed for the storage of fixed energy: do not charge the battery, but the fuel. In redox flow battery technologies, energy is not stored in the electrodes, but stored in a liquid electrolyte in the battery. Redox technology currently low capacitance. Fraunhofer Institute, Institute of Jens Noack technology sector, said: “We have passed the effectiveness of its range of more than 4-5 times, he had followed very similar to lithium-ion batteries. “
This, Tübke excited and worried: “The idea of high drama, but over the next 20 years or 30 years, still can not resolve the difficulties we have encountered.” sony vgp-bps13a/b sony vgp-bps13b/b
