Sekisui Chemical last week announced the development of a high-capacity, film-type, lithium-ion battery that uses a special coating process to triple its capacity.
The results will be announced at Eco-Products 2013 in Tokyo (December 12-14).
New organic polymer electrolyte materials such as gel-type electrolytes provide approximately 10 times the ion conductivity while taking up less space and weight. They're also flexible and can be fitted anywhere on the vehicle, which would alleviate the problem of cargo capacity that results from conventional batteries. Sekisui Chemical's battery is reportedly 200cm long, 30cm wide, and 0.3-5mm thick.
Sekisui Chemical plans to sell these long-range batteries by 2015 after conducting trials next year.
