On July 15, 2026, Envision Energy officially commenced operations at its Yichang Super Factory, marking the world's first 100 GWh-level energy storage manufacturing base covering the entire industry chain. The first batch of 790Ah large-format prismatic wound cells has already been shipped to Germany, signaling a new era in grid-scale storage capacity.
Phase I of the facility, with 40 GWh of cell production capacity, was completed in under one year. Phase II is already planned to add 60 GWh for both cells and integrated battery systems, bringing the total annual capacity to 100 GWh.
The 790Ah prismatic cell is the largest of its kind currently available. Its key performance metrics include:
The cell has obtained multiple international safety and performance certifications, making it suitable for global deployment.
The 790Ah cell is a core component of Envision's 12.5 MWh AI-powered energy storage system, which leverages artificial intelligence for optimized charge/discharge management, thermal regulation, and predictive maintenance.
This production ramp-up directly impacts B2B procurement strategies. With GWh-scale manufacturing, large-format cells become more cost-competitive and available in higher volumes, reducing lead times for utility and industrial projects. However, buyers should evaluate total cost of ownership, including cycle life and degradation rates, as these metrics now extend beyond 30 years, aligning with infrastructure investment horizons.
For buyers in specialized applications such as UAVs, marine, or high-rate industrial equipment, the mainstream storage cell specifications may differ from high-power or high-safety cell variants. Sourcing strategies should differentiate between grid storage cells and application-specific cells to avoid over-specification or under-performance.
The ramp-up of GWh-scale storage production signals a maturing supply chain for large-format cells, impacting cost and availability. For B2B clients in specialized sectors like UAVs, this highlights the importance of sourcing from flexible partners.
