Lithium polymer battery vs lithium ion battery
Lithium polymer batteries use soft pouch structures, offering greater flexibility and lighter weight, making them ideal for space-constrained designs.
Lithium-ion batteries (cylindrical or prismatic) are more standardized and structurally robust, suitable for large-scale industrial applications.
Both have similar energy performance but differ significantly in structure adaptability, weight, and cost models.
| Parameter | Li-Po Battery | Li-ion Battery |
|---|---|---|
| Electrolyte | Solid/Gel Polymer | Liquid |
| Packaging | Flexible pouch | Metal casing |
| Energy Density | 250–350Wh/kg | 160–260Wh/kg |
| Weight | 15%–30% lighter | Heavier due to casing |
| Shape | Fully customizable | Standard sizes only |
| Discharge | 3C–5C continuous | Cylindrical up to 10C |
| Safety | Swells if damaged, low explosion | Requires venting protection |
| Cycle Life | 300–800 cycles (100+ optimized) | 500–200 cycles |
| Cost | Higher tooling cost | Lower for standard models |
| Application | Compact, lightweight, custom shapes | Standardized, high durability |
Selection Guide
- Choose Li-Po batteries for compact, lightweight, and custom-shaped designs
- Choose Li-ion batteries for cost efficiency, structural stability, and standardized production
