Yin Tongyue Outlines Chery's 2027 Testing Timetable for 400 Wh/kg Solid-State Cells
Chery Automobile intends to start vehicle verification of 400 Wh/kg all-solid-state batteries in 2027 after introducing semi-solid packs in 2026.

What Happened
Addressing an automotive battery forum convened in Sichuan, Chery Automobile Chairman Yin Tongyue outlined the company's commercial electrification milestones, stating that automotive verification runs with completely solid packs will begin during 2027. Earlier passenger model installations will employ solid-liquid hybrid formats, scheduled to enter production before the close of 2026.
Chery's technological path relies on a 60-Ah cell within its Rhino S series that achieves an energy density of 400 Wh/kg using sulfide electrolytes and high-nickel ternary cathodes. Parallel development covers polymer-based cells rated at 600 Wh/kg, which the automaker states could deliver driving ranges exceeding 1,500 kilometers.

Chery emphasized that comprehensive safety validation remains a prerequisite for road adoption, mandating tests across extreme cold, thermal stress, vehicle impacts, underbody scraping, and water immersion before commercial release.
Why this matters
The timetable aligns Chery alongside domestic peers targeting passenger vehicle trials by 2027. Developing sulfide and polymer chemistries under its Rhino program provides an intermediate bridge before commercializing ultra-high-density solid packs.
