3.2V 2600mah 18650 lithium NCM battery cell for home energy storage power wall
About 18650 lithium NCM battery cell.
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 is with lithium,cobalt,manganese(LiNixCoyMnzO2) as positive electrode,short for NCM battery,the size 18mm*65mm high.
Deligreen's 18650 supplies good quality and real 2600mah capacity.
Lithium battery is the trend to replace the lead acid battery.
| Battery type | LifePO4 battery | Lead acid battery |
| Nominal voltage | 3.2V | 2V |
| Energy density | 180Wh/kg | 30WH/KG |
| Weight | Light | heavy |
| CBM | Small | big |
| Safty rate | High | low |
| Cycles | 3500 | 500 |
| Memory | NO | YES |
| Environmental protection | Environmental protection and pollution-free | pollution |
More and more people choose Lithium battery to replace the lead acid battery.Lithium is deeper cycle as to 2000 times,much longer than lead acid.You don't need to change the battery as frequently as lead acid battery,which can save your cost in battery.

NCM is one of the most widly used lithium ion batteries in our life.Compared to Lifepo4 lithium battery,NCM battery has a higher voltage 3.7V,which determines its higher energt density.180WH/KG.Lifepo4 1202H/KG.
Many big automobile groups choose NCM as E-CAR battery,such as TESLA.
Quality Testing
| Items | Test Conditions | Specification |
|
Fully charged | The use of 0.2 C5A constant current charging, when the battery voltage reaches 4.2V, instead of constant voltage charging, the charging current is gradually reduced, until the charging current is less than or equal to 0.01 C5A, setting the charging time is 8 hours. | |
|
Cycle Life | After 300 cycles of charge and discharge, the discharge capacity is measured with 0.2 C5A discharge current and 2.75V cut-off voltage. |
≥80%Nominal Capacity |
|
Storage Characteristics | The discharge capacity is measured with 0.2 C5A discharge current and 2.75V cut-off voltage after stored at room temperature for 28 days at a full charged state. |
Capacity Retention≥85% |
|
Discharge Characteristics | The discharge capacity is measured with 0.2 C5A discharge current and 3.0V cut-off voltage after full charged. |
≥100%Nominal Capacity |
| The discharge capacity is measured with 0.5 C5A discharge current and 3.0V cut-off voltage after full charged. |
0.5C/0.2C=90% | |
| The discharge capacity is measured with 1 C5A discharge current and 3.0V cut-off voltage after full charged. |
1C/0.2C=85% | |
| The discharge capacity is measured with 2 C5A discharge current and 3.0V cut-off voltage after full charged. |
2C/0.2C=80% |
