EVE Energy unveils its Chengdu solid-state battery mass production base
On September 2, 2025, the Chengdu mass production base of EVE Energy's Solid-State Battery Research Institute was officially unveiled, and the "Longquan No. 2" all-solid-state battery successfully rolled off the production line. The Chengdu base, with a total area of approximately 11,000 square meters, will have an annual production capacity of nearly 500,000 battery cells upon full production. The base will be constructed in two phases. Phase I will be completed in December 2025, with a 60Ah battery manufacturing capacity; Phase II is scheduled to achieve an annual production capacity of 100MWh by December 2026. The "Longquan No. 2" battery that rolled off the production line is a 10Ah all-solid-state battery with an energy density of 300Wh/kg and a volumetric energy density of 700Wh/L. It is primarily intended for applications in high-end equipment such as humanoid robots, low-altitude aircraft, and AI.
