Multiple Chinese battery manufacturers and automakers have confirmed plans to begin limited production of solid-state or semi-solid-state EV batteries in 2026, a coordinated push that positions China to set the pace in what has become the most closely watched technology race in the global automotive industry. The announcements — spanning CATL, WeLion New Energy, Ganfeng Lithium, and several state-backed research consortia — collectively represent $7.6 billion in committed investment through 2028, according to data compiled by the China Battery Industry Association.
Who Is Doing What
The landscape of Chinese solid-state development is broad, with multiple approaches being pursued simultaneously. CATL, the world’s largest battery maker by installed capacity, has confirmed pilot production of a condensed-matter battery — a technology the company describes as a bridge between conventional lithium-ion and true all-solid-state — with energy densities exceeding 500 Wh/kg at the cell level. Initial applications are targeted at aviation, with automotive deployment expected to follow by 2027.
WeLion New Energy, spun out of the Chinese Academy of Sciences, has already shipped semi-solid-state batteries with energy densities of 360 Wh/kg to Nio for integration into the ET7 sedan. The company announced in late 2025 that it is constructing a 10 GWh production line in Jiangsu Province, scheduled to reach full output by the second half of 2026.
Ganfeng Lithium, one of the world’s largest lithium producers, has taken a different approach, investing in oxide-based solid electrolytes through its subsidiary Ganfeng LiEnergy. The company disclosed that it delivered solid-state battery samples to Dongfeng Motor for vehicle-level testing in Q4 2025, with energy densities of 340 Wh/kg.
- CATL: Condensed-matter cell, 500 Wh/kg, aviation-first strategy, automotive by 2027
- WeLion: Semi-solid sulfide cells, 360 Wh/kg, 10 GWh line under construction
- Ganfeng LiEnergy: Oxide-based solid electrolyte, 340 Wh/kg, samples to Dongfeng Motor
- FAW/Hongqi: Sulfide-based all-solid-state prototype, 360 Wh/kg, vehicle demonstrated in early 2026
Government Support and Strategic Context
Beijing’s support for solid-state battery development is embedded in the 14th Five-Year Plan and the broader Made in China 2025 initiative. The Ministry of Science and Technology has funded at least 23 research programs focused on solid-state electrolytes since 2021, with total grants exceeding 4.5 billion yuan. Provincial governments in Jiangsu, Guangdong, and Anhui have offered additional incentives, including subsidized land, tax breaks, and guaranteed purchase agreements for qualifying battery producers.
“China’s approach is notable for its breadth. Rather than betting on a single electrolyte chemistry, the government is funding multiple parallel pathways — sulfide, oxide, polymer, and hybrid — to maximize the probability that at least one reaches commercial scale on schedule.” — Mark Hutchinson, head of Asia-Pacific research, Benchmark Mineral Intelligence
Global Competitive Implications
The scale and speed of China’s solid-state push has implications for competitors in Japan, South Korea, and the United States. Toyota, which holds the largest solid-state battery patent portfolio globally with more than 1,300 published patents, has targeted a 2027–2028 production start for its sulfide-based cells. Samsung SDI has announced a 2027 pilot line. In the U.S., Solid Power and QuantumScape continue to advance their programs, but neither has announced gigawatt-scale production timelines.
If Chinese manufacturers achieve even modest serial production of solid-state cells in 2026, they will establish an early-mover advantage in manufacturing know-how, supply-chain integration, and cost reduction — the same pattern that enabled China to dominate global lithium-ion production over the past decade. The next 18 months will determine whether that scenario materializes or whether technical and yield challenges push timelines to the right.
