What the current evidence supports

Human editorial judgment · 2026-10-29

Track; not yet

Why
The 500 Wh/kg figure is a target for 20 Ah sample cells, not a measured result on a validated cell, and the company's own chairman rates the technology at Level 4 of 9. The 20 Ah trial production was first reported in Nov 2024 and the October 2026 news reaffirms rather than advances it. Rivals (Toyota, Samsung SDI, BYD, Chery) cluster around the same 2027-2030 window, and none of the sources reviewed publishes cycle-life, yield or cost data.
Next
Watch for the first published cycle-life, charge-rate and Wh/L data on 20 Ah sulfide cells, the 2027 small-batch start at the Hefei pilot base, and any OEM vehicle-validation announcement.
