CORNEX Fires Up 80GWh Battery Plant in Yichang

CORNEX just switched on its Phase II lithium battery park in Yichang, Hubei. The commissioning wrapped up on August 9.This place is big. Designed annual capacity sits at 80GWh, and one plant alone churns out more than 30GWh per year. The site handles R&D plus large-scale production of energy storage batteries, EV batteries, and battery pack modules. CORNEX fitted the whole campus with an upgraded flexible intelligent manufacturing system, which they say raises the bar for precision and automation. The production lines are built to handle large-format cells from 500Ah to 1000Ah, so they can cover a broad range of applications across different markets.Same day, another headline: CORNEX started mass production of its 588Ah large-capacity energy storage cell. That battery targets next-generation storage projects, packing in higher energy density, better safety, and longer cycle life. CORNEX says the 588Ah product makes large-scale storage stations and commercial storage systems more economical and more dependable — a solid step toward making renewables easier to adopt at scale.For teams building stationary storage on the same large-format LFP trend, our utility scale LFP storage cabinet solution and EVE 3.2V 100Ah LiFePO4 prismatic cell wholesale follow the same "fewer bigger cells, cleaner BMS" logic CORNEX is pushing here.
588Ah Cells — Bigger Format, Better Economics
The 588Ah launch matters because it hits the pain points of utility-scale storage: too many cells, too much wiring, too much balance overhead. Fewer, bigger cells mean simpler assembly, fewer connections, and lower system cost per kWh. CORNEX is betting that large-format LFP is the path forward for storage stations that need to scale without scaling their headaches.If your project mirrors this with slightly smaller form factors, our CALB 3.2V 314Ah LiFePO4 prismatic cell wholesale and CATL 3.2V 302Ah LiFePO4 prismatic cell wholesale give you the same low-IR, high-cycle baseline at 300Ah-class sizing.
What This Means for Buyers
For procurement teams eyeing storage cells, CORNEX's Yichang ramp-up signals steady supply of large-format cells in the 500Ah-to-1000Ah range. That's good news for anyone planning utility scale battery storage farm deployments or C&I peak shaving battery system rollouts in the next few quarters.
Starmax / Darong Side Note
We're not CORNEX, but the direction is the same: grade-A cells, matched IR/voltage, export-grade packing. For commercial sites wanting the same protection logic off-vehicle, our Darong New Energy C&I peak shaving battery system ships with inspection records and foam-separated cartons, ready for ocean freight the same way CORNEX ships its 588Ah blocks domestically.
