Hitachi doubles battery life expectancy

Japanese industrial giant Hitachi has developed a new battery which could double the life expectancy of current lithium ion batteries.

Using a new manganese-based electrode material, the new batteries - which will first be used in industrial applications like wind farms and machinery - are expected to have up to ten years of useful life compared to the current theoretical limit of five years.

With more demands on battery life from mobile gadgets pushing the market, it shouldn't be too long before the power sources find their way into everyday devices.

Manganese, which is reasonably abundant, replaces the use of cobalt, which is pretty rare and expensive (if our interpretation of this indecipherable Google translation from Japanese is to be believed).
