Xiaowei Li+ UPower Series Due to the special lamination process, ultra-high rate charge and discharge performance can be achieved. Under the same discharge current requirements, the volume and weight can be reduced by about 50%, and even continuous high current discharge can be achieved at-20℃. The energy density ratio is as high as 150Wh/kg, and the cycle life is as high as 4000 cycles. Maintenance-free costs can save a lot of labor costs for enterprises and greatly reduce total operating costs.
