ZEEKR Intelligent Technology, the premium electric vehicle (EV) maker controlled by Geely Auto, has unveiled a new battery technology that can offer a car a nearly 500-kilometre (310-mile) range with just 10.5 minutes of charging, reports Hong Kong's South China Morning Post.

Zeekr's self-developed lithium-ion phosphate (LFP) battery, or "Golden Battery" and installed on its 007 electric sedan, supports 800-volt ultra-fast charging and assures owners of "swift and reliable" performance, the company said. The 75-kilowatt-hour battery, when fully charged, allows a car to go as far as 682 kilometres.

"Thanks to the optimised materials and upgraded technology, the speed is higher than what is achieved by existing nickel-cobalt-manganese (NCM) batteries," Zeekr said. "It's a new achievement by Zeekr's in-house e-power train research and development team."

The costs of producing NCM batteries are about 30 per cent higher than its LFP types, but they offer an EV a longer mileage on a single charge, according to industry data.
