Ganfeng Lithium has reportedly achieved 420 Wh/kg energy density with its existing products. The firm also developed samples reaching 500 Wh/kg.
It isn’t the only firm in China pushing the boundaries of solid-state battery innovation. In May, battery manufacturer Gotion High-Tech also started the first road tests for its next-gen all-solid-state batteries. This came after the company completed China’s first fully localized 0.2 gigawatt-hour pilot line.
Gotion High-Tech also launched the G-Yuan battery, which has a 300-watt-hours-per-kilogram energy density. According to Gotion chief scientist Zhu Xingbao, this battery will boost range and performance for new flying taxis, EVs, and humanoid robots.
CATL, meanwhile, reported this month that its solid-state batteries can achieve an energy density of 500 Wh/kg. The company is developing an electric commercial passenger aircraft.
