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