CORNEX Unveils Next-Gen “Everest” 6C Fast-Charging Battery Cell

On October 27, CORNEX held its next-generation 6C "Everest" fast-charging battery cell launch event in Xiangyang. Executive Vice President Bu Xiangnan unveiled this strategic product, which integrates high safety, extended driving range, and ultra-fast charging capabilities. Just as Mount Everest represents the ultimate pinnacle and exploration, the "Everest" battery cell embodies CORNEX's ambition and capability to push technological boundaries and set new industry benchmarks, aiming to pioneer a new era for global green mobility.

Rock-Solid Safety: A Multi-Layer Protection Foundation

Safety forms the core principle of the "Everest" battery cell. CORNEX has established a multi-level, comprehensive protection system spanning materials to system design:

Double-Sided Ceramic Separator: This significantly enhances the separator's heat resistance and resistance to thermal shrinkage, effectively reducing the risk of short circuits from localized overheating and improving the battery cell's intrinsic safety at the source.

Directional Instant-Venting Port: Featuring an innovative pressure release channel design, it enables directional and rapid energy release during thermal runaway, precisely controlling internal pressure and temperature, and steadfastly maintaining the critical safety baseline of "no fire, no explosion."

Extreme Endurance: Redefining EV Range Limits

Driving range is a key metric for evaluating the practical value of EV batteries. The "Everest" battery cell utilizes multi-level particle grading for the cathode and double-layer coating technology for the anode, achieving a mass energy density of up to 190 Wh/kg and a volumetric energy density of up to 420 Wh/L. This lays a solid foundation for a system-level pure electric driving range exceeding 1000 kilometers.

Addressing performance degradation in cold environments, the "Everest" cell incorporates highly active low-temperature electrolytes, enabling an energy retention rate of over 85% even at -20°C. Even at a low State of Charge (SOC) of just 20%, the discharge rate can still reach 1C, ensuring ample power output in extreme cold and low-charge conditions.

Summit Ascent: 6C Fast Charging for Ultimate Replenishment

Energy replenishment is the core breakthrough of the "Everest" battery cell. Through systematic innovation in cathode and anode materials and processes, it perfectly resolves the industry challenge of balancing "fast charging" with "long driving range," achieving a sustained 6C ultra-fast charging rate. On an 800V ultra-fast charging platform, integrated with CORNEX's CTP 3.0 system, the "Everest" battery cell can deliver 600 kilometers of range with just a 10-minute charge, making its energy replenishment efficiency comparable to refueling a traditional vehicle.

Just as the footsteps of climbers never cease, CORNEX's pursuit of technological innovation knows no bounds. The launch of the next-generation 6C "Everest" fast-charging battery cell marks a significant milestone in CORNEX's ascent to the pinnacle of EV battery technology and represents a new starting point toward even broader horizons. In the future, CORNEX will continue to uphold the spirit of mountaineers, providing safer, more efficient, and more reliable energy solutions to support humanity's steady transition to clean energy, carving a solid mark for Chinese intelligent manufacturing on the great journey of sustainable development.
