Envision Power said its Yichang super factory has started production. The plant makes the world's largest prismatic-wound 790Ah energy-storage cell with an energy density of 440 Wh/L; over 50% of that cell capacity is already reserved by overseas orders, effectively making initial output export-oriented. Yichang is promoted as the first global 100+ GWh full-chain energy-storage base: phase I targets 40 GWh of cell capacity and began construction in October 2025, while phase II — planned for 60 G
