3.2V 310Ah LiFePO4 Battery for Solar Energy Storage with 3000 Cycle Life and High Capacity
CATL New Lithium Iron Phosphate Battery 3.2V 310Ah LiFePO4 for Solar Energy 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 |
Choose the optimum battery for your application based on your specific requirements.
