Xin Jing Bao·2025-09-05 12:49Core Viewpoint - EVE Energy announced the unveiling of its solid-state battery production base in Chengdu, marking the successful rollout of the "Longquan No. 2" solid-state battery, which is primarily aimed at humanoid robots and high-end AI equipment rather than electric vehicles [1][2]. Group 1: Company Developments - EVE Energy's Chengdu production base covers approximately 11,000 square meters and is expected to achieve an annual production capacity of nearly 500,000 battery cells upon full operation [2]. - The "Longquan No. 2" solid-state battery has a capacity of 10Ah, with an energy density of 300Wh/kg and a volumetric energy density of 700Wh/L [2]. - EVE Energy's chairman stated that the company is committed to achieving key performance indicators for solid-state batteries, including energy densities of 400Wh/kg and 1000Wh/L by 2025, with significant investments in funding, equipment, and R&D resources [3]. Group 2: Industry Challenges - The solid-state battery industry is facing significant challenges, including high costs and R&D difficulties, which are hindering mass production [4][6]. - Current estimates suggest that the cost of solid-state batteries is 3-5 times higher than that of traditional liquid lithium batteries, with core materials like lithium sulfide being particularly expensive [7]. - Industry experts predict that mass production of solid-state batteries may not occur until 2027 to 2030, with various companies, including BYD, also working towards feasibility verification and potential mass production [5][6].
