According to EnergyTrend, Envision AESC held a commissioning ceremony for its 40GWh intelligent lithium battery project and an offline launch event for its high-capacity 790Ah battery cells in Yichang on July 15. It is reported that the first batch of mass-produced cells achieved immediate delivery upon rolling off the production line and has been shipped to overseas energy storage customers.
Looking back at the project’s progress, the project was signed on October 9, 2025, and construction commenced on October 27 the same month, achieving official production launch in just over nine months. As introduced, Envision AESC’s Yichang Gigafactory serves as the core production base for the company’s energy storage batteries and is also the world’s first full-industry-chain base planned for a 100GWh-level energy storage capacity.
The newly launched 790Ah cell is currently the industry’s largest-capacity wound prismatic energy storage cell. It delivers a rated energy of over 2.5 kWh per unit, a volumetric energy density exceeding 440Wh/L, a cycle life of more than 12,000 times, and a DC energy conversion efficiency of no less than 96.0%.
On the demand side, Envision AESC maintains a full order backlog for its energy storage products, with all global manufacturing bases operating at full production capacity.
The mass production and launch of the 790Ah energy storage cell in Yichang marks a crucial milestone in Envision AESC’s iteration of high-capacity energy storage cells and the implementation of its global production capacity strategy. Previously, Envision AESC has successively developed and mass-produced 300Ah and 500Ah+ energy storage cells. The new 790Ah product represents a significant upgrade to the company’s existing high-capacity wound-cell product lineup.
