Home “headache” the makers of electric cars is the power reserve while maintaining a reasonable mass of the vehicle. Several startups from Japan has already achieved impressive results.
As says the publication Nikkei, the company 3Dom – a startup that appeared in the Tokyo Metropolitan University in 2014. It was created by Professor Kiyoshi Kanamura, who gathered around him a team of engineers of major companies – manufacturers of household appliances such as Panasonic and manufacturers. Currently, the startup has 70 professionals.
After 2 years 3Dom plans to begin commercialization of lithium metal batteries, which are comparable in dimensions and weight will allow you to get twice as much energy than today’s lithium-ion power sources. This will significantly increase the range of electric vehicles.
The Japanese company intends to replace the carbon materials to metallic lithium. He can significantly increase capacity, but prone to short circuits and fire.
To overcome the negative reaction, the company has developed a special separator which suppresses the unevenness of the chemical reaction. The separator has a spherical hole with a diameter of several hundred nanometers, located in the perfect manner. Optimal size and location of the holes provide a uniform flow of ions and a uniform chemical reaction.
The separator is made of polyimide heat – resistant plastic that will not burn even at a temperature of 400 degrees Celsius. Another startup, Azul Energy from Sendai city, focuses on the production not the whole battery and its individual elements. According to its Director, Hiroshi Yabu, special catalysts for battery on the basis of oxygen and metals will speed up the discharge process and increase the overall capacity and hence the reserve, in 3-10 times.
