Description

The 684Ah LiFePO4 battery cell employs advanced stacking technology, achieving a volumetric energy density exceeding 440 Wh/L, outperforming similar products. It integrates a "thermal-electric separation" design with a 3D cooling structure, optimizing thermal management to boost operational safety and long-term reliability. With a lifespan of over 20 years, it supports sustained operations and fits various container sizes, including 10-foot, 20-foot, and 30-foot options. Its high energy density and ease of maintenance lower the levelized cost of electricity by 8% compared to conventional approaches, speeding up project deployment and improving economic returns.
