- Eve Energy has rolled out two new all-solid-state batteries, targeting the consumer electronics and EV sectors respectively.
- The development builds on the company's rollout of another solid-state battery last year and expands its product portfolio.
Eve Energy has rolled two new all-solid-state batteries off its production line, marking a significant step for the Chinese battery maker in the commercialization of next-generation technology.
The two new battery models, dubbed Longquan No. 3 and Longquan No. 4, were officially produced on March 17 at a rollout ceremony held at the company's manufacturing base in Chengdu, Sichuan province, according to a Wednesday statement.
The Longquan No. 3 all-solid-state battery is primarily designed for the consumer electronics sector. It can operate in low-pressure environments below 2 megapascals (MPa) and features high volumetric energy density.
The Longquan No. 4 all-solid-state battery focuses mainly on the electric vehicle power battery sector. Its capacity has been increased to 60 ampere-hours (Ah), and it can currently cycle under pressures of 5 MPa or less.
This ability to cycle under specific pressures means the Longquan No. 4 has initially demonstrated potential for practical application. Company executives attended the ceremony to jointly witness this milestone in technological innovation.
In 2022, Eve Energy put into operation a 9 GWh conventional battery production line in the Chengdu Economic and Technological Development Zone. It subsequently launched the construction of a mass production base for its solid-state battery research institute in Chengdu.
This helped the company gradually form a product portfolio covering consumer batteries, power batteries, and energy storage batteries at the new production base. These battery products are widely used in fields such as EVs, the low-altitude economy, and humanoid robots.
In 2025, the Chengdu production base completed the construction of manufacturing capabilities for 10 to 60 Ah all-solid-state batteries. The company thus preliminarily established the production and manufacturing processes for next-generation solid-state batteries.
The progress led to the release of the Longquan No. 2 all-solid-state battery in September 2025. That earlier cell was launched targeting humanoid robots, low-altitude aircraft, and artificial intelligence equipment.
Eve Energy is currently continuing to expand its solid-state battery production facilities in Chengdu. The facility, with a total area of 11,000 square meters, is scheduled to achieve an annual production capacity of 100 GWh by December 2026, according to a statement last September.
The battery maker had selected the sulfide and halide solid-state electrolyte technology routes.
Eve Energy ranked as the world's eighth-largest EV battery maker in 2025 with a 2.6% market share, according to data from South Korean market research firm SNE Research.
