Cell Specification
| Item | Specification and comments |
|---|---|
| Cell model | CB310 – 280Ah 3.2V prismatic LiFePO4 cell |
| Chemistry | LiFePO4 (LFP) prismatic cell for energy storage systems |
| Typical capacity | 280Ah – defined under CATL standard charge/discharge procedures |
| Typical energy | 896Wh (3.2V × 280Ah) |
| Operating voltage range | 2.5~3.65V (standard); absolute 2.0~3.65V depending on temperature |
| Impedance (1kHz) | 0.17 ± 0.05mΩ |
| Shipping capacity | 112 ± 1Ah (≈40% SOC fresh cells) |
| Standard charge power | 0.25P at 25 ± 2°C (≈224W for a fresh 896Wh cell) |
| Standard charge voltage | Cell max voltage 3.65V |
| Standard charge method | 0.25P constant power to 3.65V, rest 5min, then 0.1P constant power at 3.65V |
| Standard discharge power | 0.25P at 25 ± 2°C (≈224W) |
| Maximum continuous discharge power | 0.5P (≈448W) |
| Discharge cut-off voltage | 2.5V for T > 0°C; 2.0V for T ≤ 0°C |

| Absolute charging temperature | 0~60°C (stop charge outside this range) |
| Absolute discharge temperature | -20~60°C (stop discharge outside this range) |
| High/low-T capacity | ≈280Ah @ 55°C, ≈155Ah @ -20°C (0.25P, specified voltage window) |
| Temperature rise (continuous) | ≈10°C under standard discharge conditions |
| Temperature rise (pulse) | ≈5°C at 500A for 10s at any SOC |
| Safety / development status | Sample in development stage; process freeze and mass-production specs to be re-defined |
| End-of-life criteria | Stop use when internal resistance ≈200% initial or capacity ≈60% of typical (≈168Ah @ 25°C) |
| Recommended preload force | 500–5000N on fresh cell for pack design; swelling force at 60% SOH ≈40000N |
