Chinese battery giant CATL has officially released its latest 587Ah large-capacity battery cell, integrated into the next-generation TENER energy storage system. This new cell achieves a volumetric energy density of 430 Wh/L while demonstrating enhanced safety compared to traditional small-capacity cells. Although such parameters are becoming common in China's competitive battery industry, CATL's innovation lies in its 48% lifecycle energy output improvement through bionic SEI membrane technology and a claimed 25-year lifespan with zero capacity degradation during initial operation. The development reflects intensifying competition among Chinese manufacturers like Gotion Hi-Tech and Hithium in the "300+Ah" energy storage cell race, with the 587Ah specification emerging as a potential new LFP industry benchmark.
