With capacity expansion underway and industry timelines converging on 2027, the solid-state race is accelerating. China‘s battery manufacturer EVE Energy recently held a rollout ceremony at its Chengdu base for two solid-state battery models, Longquan No.3 and Longquan No.4. The two batteries are designed for different application scenarios. Longquan No.3 targets the consumer electronics segment and can operate under low-pressure conditions below 2 MPa, offering high volumetric energy density as its core advantage. Longquan No.4, meanwhile, is aimed at automotive applications, with capacity increased to 60 Ah. It is currently capable of cycling under pressure conditions of ≤5 MPa, demonstrating early-stage readiness for practical deployment. EVE Energy rolls out two solid-state batteries Public information shows that in 2022, EVE Energy established its presence in the Chengdu Economic Development Zone, building a 9 GWh production line and launching the construction of a solid-state battery research institute and mass-production base. Once fully operational, the base is expected to achieve an annual output of around 500,000 cells. Total planned capacity will be developed in two phases. The first phase, completed in December 2025, supports 60 Ah cell production, while the second phase is scheduled for completion in December 2026 with annual output reaching 100 MWh. In September last year, the company rolled out the Longquan No.2 10 Ah solid-state battery at the same facility. This battery targets high-end applications such as humanoid robots, low-altitude aircraft and AI-related equipment. Solid-state batteries have become a key focus of industry competition. At the end of last year, FAW Hongqi initiated vehicle validation for its all-solid-state battery, with the first prototype model Hongqi Tiangong 06 rolling off the line. Hongqi Tiangong 06 equpped with all-solid-state battery rolls off the line SAIC MG’s MG4 semi-solid-state Anxin edition also began deliveries in December, becoming the world’s first and only mass-produced model equipped with a semi-solid-state battery. In addition, leading players including CATL and BYD have set timelines around 2027 for large-scale solid-state battery production. From a market positioning perspective, EVE Energy remains in the catching-up tier. According to SNE Research, its power battery installations reached 1.8 GWh in January 2026, ranking ninth globally with a market share of about 2.4%.
