- CATL entered 20 Ah trial production of sulfide-based all-solid-state batteries, targeting an energy density of 500 Wh/kg.
- CATL expects to begin small-scale production in 2027, with output limited at first and mass production around 2030.
- Robin Zeng said at the Summer Davos Forum in June that all-solid-state batteries had reached only level 4 on a 1-to-9 scale; stable contact between solid components remains a hurdle for CATL’s sulfide-based system.
- CATL held 39.9% of the global EV battery market in the first half of 2026, according to SNE Research.
- Toyota aims to launch its first all-solid-state-battery EV in 2027 or 2028; its prototype claims 1,200 km of range and charging in under 10 minutes, while mass-market production waits until closer to the decade’s end.
- Samsung SDI targets mass production of its SolidStack all-solid-state batteries in the second half of 2027.
- BYD plans limited sulfide-based all-solid-state production in 2027 and a mass-production ramp by 2030; its second-generation Blade LFP batteries already deliver more than 1,000 km of CLTC range.
Why it matters: CATL, Toyota, Samsung SDI and BYD cluster their solid-state road maps around 2027, but the 39.9% market-share leader still plans mass output near 2030. That gap makes the 20 Ah trial a manufacturing test, not evidence of immediate EV-market availability.
