Product overview
The Guizhou Super Energy Era Technology Co., Ltd. Skyward 21700/6.0 is a cylindrical battery cell for power applications with demanding discharge-rate and safety requirements. Its physical architecture combines NCM-Si/Gr chemistry with the 21700 format and a maximum height of 72 mm. The specified configuration provides 6.0 Ah rated capacity and 21.6 Wh rated energy at a nominal 3.60 V. Integration centers on the shared cell format, which supports replacement or upgrade within equipment designs that use it.
Electrical integration must accommodate the 2.50–4.20 V operating range, a maximum charge rate of 2C and maximum continuous discharge of 10C. Charging is limited to 0–45 °C, while discharging permits −20–60 °C. Cycle-life selection depends on the operating discharge rate: the two stated conditions are 1C/1C, 500 cycles × 80%, and 2C/1C, 400 cycles × 70%. GB 31241-2022 is the applicable standard. These specifications define a cell-level power component for incorporation into equipment.
