Japan's Nikkei newspaper said that although Toyota is quiet on the details of this new technology the manufacturer did say the improvement stems from the production of single crystals of lithium cobalt oxide which theoretically could improve battery capacity ten fold.
If this is the case Toyota could potentially set the stage for EVs with a 1600 kilometre plus range.
Additionally, the new technology is said to weigh less and take up less space than lithium-ion batteries currently under development.
Toyota jointly developed the new lithium-ion technology with Japan’s Tohoku University.
If successful we expect to see production use of this technology in both hybrid and plug-in EVs by around 2015.
