Japan has developed a new heat-resistant technology for electric vehicle 3.7v 2200mah 18650 lithium battery

Japan's Daikin Industries and Japan's Kodo Paper Industries have jointly developed a high heat-resistant technology for lithium 3.7v 2200mah 18650 lithium battery for electric vehicles. The new technology does not require a battery cooling system, which reduces the weight of the vehicle while reducing its own power consumption, and can increase the driving distance on a single charge by 30-40%. It can also prevent battery spontaneous combustion accidents and improve driving safety.

Japan's Daikin Industries and Japan's Kodo Paper Industries have jointly developed a high heat-resistant technology for lithium 3.7v 2200mah 18650 lithium battery for electric vehicles. The new technology does not require a battery cooling system, which reduces the weight of the vehicle while reducing its own power consumption, and can increase the driving distance on a single charge by 30-40%. It can also prevent battery spontaneous combustion accidents and improve driving safety.

Existing automotive lithium 3.7v 2200mah 18650 lithium battery generate heat due to chemical reactions when generating electricity. When the temperature rises to above 45 degrees, the power generation performance decreases and a cooling system needs to be installed. In the hot summer season, the full operation of the cooling system can cause a decrease in efficiency and shorten the driving distance by about 30%.

The new technology uses fluorine compounds to replace flammable electrolyte components. The new electrolyte can work normally even if the temperature rises to 60 degrees. The insulation material made of plant fibers through fine processing is more resistant to high temperatures and has lower shrinkage than the current common resin film products, which can greatly improve the heat resistance of the insulation components. The binder used for the electrode has been replaced with a high-heat-resistant material, which will not dissolve even at high temperatures.

At present, the new electrolyte products have been provided to automobile and battery manufacturers for trial use, and the new electrode products are also in the trial plan. The manufacturer hopes to commercialize the product by 2020.
