About 18650 Lithium NCM Battery Cell
- Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and uses a non-aqueous electrolyte solution.
- Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
- 18650 lithium ion battery uses lithium, cobalt, manganese (LiNixCoyMnzO2) as positive electrode, abbreviated as NCM battery, with dimensions 18mm × 65mm high.
- Deligreen's 18650 supplies good quality and real 2600mAh capacity.
Lithium Battery: The Future Replacement for Lead Acid Batteries
| Battery Type | LiFePO4 Battery | Lead Acid Battery |
|---|---|---|
| Nominal Voltage | 3.2V | 2V |
| Energy Density | 180Wh/kg | 30Wh/kg |
| Weight | Light | Heavy |
| CBM | Small | Big |
| Safety Rate | High | Low |
| Cycles | 3500 | 500 |
| Memory | No | Yes |
| Environmental Protection | Environmental protection and pollution-free | Pollution |
More and more people choose lithium batteries to replace lead acid batteries. Lithium offers deeper cycles up to 2000 times, much longer than lead acid. You don't need to change batteries as frequently as with lead acid, which can save costs.

NCM is one of the most widely used lithium ion batteries. Compared to LiFePO4 lithium batteries, NCM batteries have a higher voltage of 3.7V, which provides higher energy density (180Wh/kg vs LiFePO4's 120Wh/kg). Many major automobile manufacturers choose NCM for electric vehicles, such as Tesla.
Quality Testing
| Items | Test Conditions | Specification |
|---|---|---|
| Fully Charged | Using 0.2 C5A constant current charging, when battery voltage reaches 4.2V, switch to constant voltage charging until charging current ≤ 0.01 C5A, with 8-hour charging time limit | |
| Cycle Life | After 300 charge/discharge cycles, measure discharge capacity with 0.2 C5A discharge current and 2.75V cut-off voltage | ≥80% Nominal Capacity |
| Storage Characteristics | Measure discharge capacity with 0.2 C5A discharge current and 2.75V cut-off voltage after stored at room temperature for 28 days at full charge | Capacity Retention ≥85% |
| Discharge Characteristics | 0.2 C5A discharge current, 3.0V cut-off voltage | ≥100% Nominal Capacity |
| 0.5 C5A discharge current, 3.0V cut-off voltage | 0.5C/0.2C = 90% | |
| 1 C5A discharge current, 3.0V cut-off voltage | 1C/0.2C = 85% | |
| 2 C5A discharge current, 3.0V cut-off voltage | 2C/0.2C = 80% |
