Panasonic Corp has developed more powerful batteries for use in everything from laptops to electric vehicles, the Japanese electronics maker said today.
The new lithium-ion batteries are 20 per cent to 30 per cent more powerful than current batteries, according to Osaka-based Panasonic.
They can raise the cruising range of electric vehicles (EVs) on a single charge from 200 km to about 270 km, it said.
Major auto makers around the world are developing electric and plug-in vehicles, intensifying the race to produce better lithium-ion batteries. Demand is expected to grow for their use in such vehicles, not just laptops and other gadgets.
Panasonic has a joint venture with Toyota Motor Corp that supplies batteries for hybrid cars, including the Prius and plug-in models.
But, Panasonic said it was now in talks with about 10 auto makers to supply the new battery, underlining the breakdown of such tie-ups involving batteries for green autos.
