Contemporary Amperex Technology Co Ltd, the world's largest battery maker for electric vehicles, unveiled on Wednesday its cutting-edge condensed battery and claimed that it will soon be mass produced.

At Auto Shanghai on Wednesday, CATL said that new battery, with an energy density of up to 500 watt hours per kilogram, can achieve high energy density and high level of safety at the same time.

"Meeting customers' requirements is the core driving force that drives technological innovation for CATL," said Wu Kai, chief scientist of CATL.

The battery giant will also launch the automotive-grade version of condensed batteries, which are expected to be put into mass production this year.

Last year, CATL unveiled Qilin battery with the highest integration efficiency in the world, and it has started mass production this March.
