TSUKUBA, Japan (Kyodo) -- A Japanese research team has developed small and safe lithium-ion batteries which could be used for electric and gas-electric hybrid vehicles, it said Friday.

The team, formed by researchers of the National Institute of Advanced Industrial Science and Technology in Tsukuba, Ibaraki Prefecture, and Toyota Motor Corp., said the cell is made of solid electrolyte membrane and is one-200th of a millimeter thick.

Putting the new cells together would produce as much electricity as conventional liquid electrolyte batteries, it said.
