Product Description:
21700 Battery Cells are advanced cylindrical rechargeable lithium batteries designed to deliver higher
energy density, longer runtime, and improved thermal performance compared with traditional formats. With a diameter of 21mm and length of 70mm, 21700 cells strike an optimal balance between capacity, power output, and safety, making them one of the most popular choices for modern industrial, commercial, and energy storage applications.
Core Competitive Advantages
1. Capacity and density both increase, reducing assembly costs
Single-cell capacity 3000-5000mAh, approximately 30%-50% higher than 18650, with the same system reducing the number of cells by 20%-30% and simplifying the PACK design, lowering BMS and structural component costs.Energy density 180-260Wh/kg, supporting 2C-11C fast charging and high-current discharge. The lithium-ion system can sustain discharge at 25-50A, and the lithium iron phosphate has a cycle life of ≥3000 times (80% DOD). The terminal replacement frequency is significantly reduced.
