Capacity Comparison
Flat vs. Cylindrical Lithium Polymer Batteries
- Capacity Difference: Cylindrical batteries typically offer higher capacity (up to 3,500mAh) compared to flat batteries (typically up to 2,000mAh)
- Manufacturing Process: Cylindrical batteries use winding process for more electrode material
- Applications: Cylindrical for high-power needs (tools, EVs, drones); Flat for space-constrained devices (phones, tablets, wearables)
