CORNEX presented LFP cylindrical battery cells in 13Ah, 20Ah, 30Ah, and 50Ah capacities, designed for diverse operating conditions.

The 20Ah LFP battery cell features an all-tab design and supports 1C charging and 2C discharging. Operating from -30°C to 60°C, it retains over 85% discharge capacity at -20°C and over 80% charging capacity at low temperatures. With more than 2,500 cycles under 1C fast-charging conditions, it is suited to applications requiring frequent charging. A built-in bidirectional pressure-relief structure further enhances safety. The 20Ah battery cell meets applicable Chinese national standards for EV and energy storage applications, along with relevant international requirements, including UL, IEC, UN, and RoHS.

 

Designed for high-power output and cold-weather operation, the 13Ah LFP battery cell delivers instantaneous discharge rates of up to 35C and supports 10C discharge at -30°C. Its cycle life reaches the 10,000-cycle range under 4C conditions. Developed to rigorous automotive-grade standards, the battery cell has also undergone extreme-condition validation based on U.S. standards.


Sodium-Ion Battery Cells: Performance Across a Wide Temperature Range

CORNEX also showcased 10Ah and 15Ah sodium-ion cylindrical battery cells. The series supports discharge rates of up to 30C, with peak current reaching 450A. Cycle life exceeds 8,000 cycles at 1C and reaches 4,000 cycles at 5C. With an operating temperature range of -40°C to 70°C, the battery cells retain at least 90% discharge capacity at -30°C. They have passed nail penetration and thermal runaway tests and support 0V over-discharge, enhancing safety during storage and transportation.
