CATL chief: solid-state batteries at ‘level 4 of 9,’ no leap until 2030

Robin Zeng Yuqun, the founder and chairman of CATL, the world’s largest EV battery maker, just poured cold water on the solid-state battery hype, saying the much-anticipated technology is only at “level four” of a nine-step readiness scale.

Speaking at “Summer Davos” in China this week, Zeng predicted that an inflection point for the technology won’t arrive until 2030 — and even warned that its commercial viability has yet to be established.
