CATL 310Ah 3.2V Lithium Iron Phosphate Cell with 3000 Cycle Life for Solar Storage
DIY your battery pack - what type of lithium battery are you going to choose? The choice depends on the cathode material. Lithium-ion batteries are divided into LCO, LMO, LNO, LFP, NCA, and NCM types.
| Cathode Material | Chemical Composition | Nominal Voltage | Energy Density | Cycle Life | Cost | Safety |
|---|---|---|---|---|---|---|
| LCO | LiCoO2 | 3.7V | Medium | Low | High | Low |
| LMO | Li2Mn2O4 | 3.6V | Low | Medium | Low | Medium |
| LNO | LiNiO2 | 3.6V | High | Low | High | Low |
| LFP | LiFePO4 | 3.2V | Medium | High | Low | High |
| NCA | LiNixCoyAl(1-x-y)O2 | 3.6V | High | Medium | Medium | Low |
| NCM | LiNixCoyMn(1-x-y)O2 | 3.6V | High | High | Medium | Low |
