| Types of Lithium ion cells | Characteristics |
| LCO | High energy density, Long run time, Low charging and discharging rate |
| LMO | High thermal stability, Low internal resistance, Lower Capacity |
| NCA | High energy density, Fast charging capability, Long life span |
| NMC | Higher energy density, Longer life cycle, Slightly lower voltage generation |
| LFP | Long life cycle, Low cost, Excellent safety, Lower nominal voltage which reduces specific energy |
| LTO | Extremely long life, Rapid battery charging, Enhanced Safety, Low energy density |
