Program of the German electric car battery comparison

According to reports by CCPIT Electronics ; Information Industry Sub, when the oil runs out, it is expected that the electric car, hope it can to protect the environment, a new impulse to the community. Experiments show that electric vehicles can meet the expectations of the people, and find the ideal program of the cells with the objective of the researchers.

If you can not really get to 2030, represented the development of national plans electric vehicle scene - Germany five million electric cars on the behavior of the street - look back. The vehicle engine was born 30 years ago, electric cars had already created on the street, and a significant speed record: 1899 Belgian Camille Jenatzy drive their own vehicles built faster than 100 miles per hour. Turn of the century, has caused the power in the taxi fleet in New York. The fact, however, participation in the program in providing energy for battery electric vehicles, has stagnated their development time.

Compared to the combustion engine to power as the power advantages are obvious: speed, speed, power up to 3-4 times, driving noise and requires no driver installation. However, the shortcomings of electric vehicles is also an important point is that power always eaten quickly.

apply from the global perspective, researchers and developers to batteries as priorities reflect lithium-ion current research.
Beginning of the nineties, Sony introduced its first in a small lithium-ion battery, Yu you with the performance and long life, time and load quickly on short small devices like mobile phones, laptops, and flight model Fangmiandedao demand. In the automotive area is first prepared, lithium-ion batteries use lithium as an electrode material is not only a high voltage lead and easily with other elements of the reaction.

In the notebook would even if the battery is a minor injury, and only in extremely high temperatures and high voltage loads lead to loss of battery cells in the air, making the computer on fire. However, said the German state of Baden Fraunhofer Institute for Chemical Technology of the battery researcher Jens Tbke Pfinztal: The car was completely different. Save battery of the vehicle too much energy, you can even a bomb. In the laboratory and factory, a single voltage below 3.6 volts, then change as soon as the short-circuit and thermal expansion in the final battery has a quantity of a single voltage, in this case, a high energy density, even a light touch, the consequences would not to imagine.

For users, it is important to recognize what is most useful in terms of their own.

Security: Department of Wrzburg M Fraunhofer Institute for Silicate Kai-Christian? Miller had tried to replace non-flammable polymers using liquid fuel to the battery, but the electrode is by the effects of the frozen plastic extension of the charging time can be influenced in a great performance.

Saxon Joint Venture Li-Tec has other options to address these problems attempted security. In general, to battery manufacturers a piece of plastic membrane with two electrodes at a temperature of 140 degrees separated from each other using time Dan is like the plastic base plate, such as melting point, probably caused by Duan Lu. Li-Tec has ceramic particles can be used as a covering membrane that can withstand 700 degrees Celsius, but decreases the battery power. On the other hand say that the loading and unloading not eliminated after 4000, which requires daily recharging electric cars is very important. Li-Tec Corporation launches next year, this car is safe and durable batteries.

Sustainability: Society and lithium titanate can with great loading and unloading of at least 15,000 times (2,000 times the value of the operator excellent) are carried out. The battery life of up to years in medical ten in the well of the application of medical technology of great value.

Delivery: If you want to save more energy in a small room, you can add Iwo electrode. In theory, Iwo to three times more than the electrodes in lithium-ion polymer classic. In the laboratory, this approach may seem bright future, but only 20-40 days of discharge, after an almost unusable.

Fast Charge: If you want to load too quickly, iron phosphate electrode materials for good results. This case, cell phone batteries charged in 20 seconds - at least in the laboratory is the case, but it takes a lot of power.


For the battery-electric vehicle with gasoline or diesel-class driving range transport and the safe and economic for the moment, or can not be reached, the metal-air battery as well. In the metal-air battery was oxygen from the air and lithium reagents. IBM Fellow Chandrasekhar Narayan said: It's like a combustion engine battery. Now the smoke into the air to the vehicle with gasoline and burned, the air for the electrochemical reaction for use in the future. IBM hopes in this way the use of electric mileage of 800 kilometers - more battery Lithium-ion power more than 10 times. IBM plans to five years after the first sample to produce, while other researchers should be extremely cautious in this research it is time for decades.

Finally, we discuss an old program that was originally developed for the storage of fixed energy: not charging the battery, but the fuel. Redox-Flow Technology Stack energy stored in the electrodes, but the battery is stored in a liquid electrolyte. the ability of the technology is now low redox.

This Tbke excited and worried: The idea of the very strange, but the next 20 years or 30 years old, still does not solve our problems.
