Cornex New Energy (Cornex) has signed a suite of energy storage battery cooperation agreements with a combined volume of 50 GWh at CIBF 2026 in Shenzhen, covering utility-scale storage, commercial and industrial applications, overseas projects, and residential storage segments.
The company signed framework agreements with five partners: CRRC Zhuzhou Institute, CLOU Electronics, Wolong Energy Storage, Cubenergy, and Growatt. The largest single deal is a 25 GWh large-capacity storage battery cooperation with CRRC Zhuzhou Institute. Cornex also sealed a 10 GWh procurement pact with CLOU Electronics, plus 5 GWh agreements respectively with Wolong Energy Storage, Cubenergy, and Growatt.
Under the agreements, Cornex will supply its full portfolio of energy storage cells, including 648 Ah, 588 Ah, 314 Ah, and 100 Ah models. The 588 Ah large-format LFP cell — the company’s flagship for utility-scale systems, featuring 190 Wh/kg gravimetric energy density, 419 Wh/L volumetric energy density, 96.5% energy efficiency, and over 12,000 cycles — will be mainly deployed in projects with CRRC Zhuzhou Institute, CLOU Electronics, Wolong Energy Storage, and Cubenergy. For Growatt, Cornex will provide 100 Ah and 314 Ah cells targeted at the overseas residential storage market.
Cornex pairs the 588 Ah cell with its CTP3.0 module-free integration platform and M6 energy storage system. The CTP3.0 design integrates 104 cells into one pack with 195.68 kWh rated energy, while the M6 20-foot container system delivers 6.25 MWh rated energy, equipped with top-outlet thermal management, active-balancing BMS, and AI-powered operation and maintenance algorithms.
The 50 GWh deals highlight China’s storage industry trend toward larger-format cells and higher-density containerized systems, helping developers lower system costs, land occupation, and balance-of-system complexity.
