DETROIT– Daimler AG is planning to roll out a hybrid version of its Mercedes-Benz flagship S-Class luxury sedan that uses a kind of battery already widely used in consumer electronics, according to the Web site Daimler said that it has adapted lithium-ion technology to meet demanding automotive requirements. The new battery will be used in the S 400 BlueHYBRID beginning next year.

Lithium-ion batteries, already widely used in laptops and other gadgets, are smaller yet more powerful than the nickel-metal hydride batteries used in gas-electric hybrids like the Japanese automaker’s Prius.
