SAIC Motor announced full solid-state battery mass production in 2026, with 2027 vehicle launch; GAC Group confirmed same-year rollout. This marks the first time Chinese OEMs have given a clear full solid-state battery mass production timeline, ahead of Toyota and other international giants. Data shows Chinese enterprises hold 65% of global solid-state battery patents, establishing first-mover advantage at the intellectual property level.
Mass Production Timeline: Chinese OEMs First to Give Clear Nodes
Full solid-state batteries are regarded as the ultimate replacement for lithium-ion batteries, but mass production timing has always been the industry's biggest question mark.
SAIC Motor recently made it clear: full solid-state battery mass production in 2026, mounted on production vehicles in 2027. GAC Group also confirmed full solid-state batteries will be on vehicles in 2026. This timeline means Chinese listed automakers have, for the first time, made more aggressive mass production commitments than international giants like Toyota and BMW.
Reviewing the solid-state battery technology spectrum:
- Semi-solid batteries: Already in mass production, QingTao Energy's 360Wh/kg powers SAIC IM L6, WeLion's 320Wh/kg powers NIO ET7
- Full solid-state batteries: Still in engineering validation, energy density target 400-500Wh/kg, expected scale production 2028-2030
| Stage | Timeline | Energy Density Target | Key Tasks |
|---|---|---|---|
| Basic Research | 2026-2027 | 300Wh/kg | Material systems, interface mechanisms |
| Engineering Validation | 2028-2029 | 400Wh/kg | Small-batch vehicle testing, process validation |
| Industrialization | 2030 | 500Wh/kg | Scale production, cost control |
Patent Landscape: Chinese Enterprises Hold 65% Globally
In global solid-state battery patent competition, Chinese enterprises hold an absolute leading position with 65% share. This means regardless of how the final technology route converges, Chinese enterprises' first-mover advantage at the intellectual property level is established.
Patent distribution:
- Chinese enterprises: 65%, concentrated in semi-solid and oxide routes
- Japanese enterprises: 18%, Toyota and Panasonic dominate sulfide route
- Korean enterprises: 10%, Samsung SDI and LG Chem follow
- European/American enterprises: 7%, startups like QuantumScape and Solid Power
Toyota invested approximately 200 billion yen developing sulfide full solid-state batteries, targeting 2027-2028 vehicle rollout; BMW cooperates with Solid Power planning full solid-state battery models before 2030. But Chinese enterprises' industrialization pace is clearly faster.
Technology Routes: Three Routes Advancing in Parallel
The solid-state battery technology route contest is far from over. Three current directions each have advantages and disadvantages:
- Sulfide route (Toyota, Samsung SDI): Highest ionic conductivity, but poor chemical stability, reacts with moisture
- Oxide route (mainly Chinese enterprises): Good stability, low cost, but high interface impedance, difficult processing
- Polymer route (CATL etc.): Good flexibility, easy processing, but low room-temperature ionic conductivity
SAIC QingTao's person in charge, facing skepticism, clearly stated confidence in faster full solid-state technology scale-up. Li Yuanheng and other supply chain companies also stated that although challenges are significant, the full solid-state battery direction is the inevitable trend of NEV development.
Procurement Timing Advice for Overseas Buyers
For potential buyers in Central Asian and Russian markets, solid-state battery technology progress sends important selection signals:
- No need to wait for full solid-state now. Semi-solid batteries are already in mass production, energy density 300-360Wh/kg, range 700-1000km, fully meeting current needs
- Full solid-state models will concentrate on market after 2028. Buyers planning long-term vehicle holding or pursuing extreme range can wait for this time node
- Patent advantage means Chinese supply chain dominance. Buyers choosing Chinese brands will have better guarantee for future solid-state battery upgrades and parts supply
Overseas buyers tracking solid-state battery technology progress through EX1000.COM can plan procurement cycles in advance and make optimal choices between the semi-solid maturity period and full solid-state early period.
