Sony apparently made the decision assuming that a large percentage of the market will soon consist of electric car batteries. It is not yet clear whether Sony has been forced into this expansion by failing to thrive elsewhere. Sony will reportedly offer its lithium ion batteries to auto makers for both electric and plug-in hybrid cars.
According to company information, Sony is convinced that the demand for such batteries will increase sharply in the near future, but no specific information about the particulars of their batteries has been released. The first prototypes of the lithium ion batteries, however, are allegedly 257mm x 182mm and are guaranteed to be long-lasting.
According to Japanese media sources, Sony has already offered its batteries to several domestic and international auto makers.
