SAIC Motor said its partner Qingtao Power’s all-solid-state battery production line in Anting has achieved full-line commissioning, and the firm expects sample cells to roll off the line by the end of this year, with prototype vehicles to undergo testing next year and commercial mass-delivery scheduled for 2027, as reported by IT-home.
SAIC has previously described technical targets for the new solid-state chemistry: a gravimetric energy density above 400 Wh/kg, a volumetric energy density above 820 Wh/L, and single-cell capacities greater than 75 Ah. Those figures were disclosed in earlier corporate communications and press briefings and have been repeated in trade outlets and SAIC’s technology summaries.
The company also provided safety performance data for the chemistry, reporting that cells passed nail-penetration tests and sustained exposure in a 200°C thermal chamber without catching fire or exploding, and that low-temperature capacity retention exceeds 90 per cent. SAIC’s published materials present these results as laboratory and validation data linked to its stated development roadmap.
SAIC’s engagement with solid-state development dates back several years and includes collaborative investment with Qingtao Energy; reporting indicates SAIC has invested in the partner and that a joint laboratory was formed to accelerate development. Industry outlets cite those earlier steps as part of a multi-year program to scale the technology from laboratory samples to vehicle use.
Analysts warn that sample-line commissioning and controlled safety tests are milestones but not proof of long-term manufacturability, cost efficiency or field reliability. Commercial success will depend on repeatable mass-production yields, supply-chain readiness and real-world durability data gathered through fleet testing. No pricing or commercialization terms were announced in the interaction; currency conversions are not applicable.
By comparison, SAIC is not alone in pursuing the commercialization of all-solid-state batteries. GAC Group recently built China’s first large-capacity (60 Ah+) solid-state battery production line, with small-batch cells already rolling and mass production pencilled in for 2027-2030. Chery – another Chinese automaker – has unveiled a 600 Wh/kg solid-state battery module and is targeting pilot-vehicle use in 2026 and a broader rollout in 2027. Meanwhile, battery maker Sunwoda (backed by Li Auto) is developing a 400 Wh/kg cell with a 1,000 km projected range and 1,200-cycle lifespan. On the other hand, CATL has pushed back on some of the more ambitious rumours, saying mass-scale solid-state production is not expected until around 2030, despite continued R&D investment.
