Li-Ni-Mn-Co Cells

Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC) Rechargeable Battery Cells

​

Standard 18650 and 20700, and by request other, format rechargeable battery cells.

​

Lithium Nickel Manganese Cobalt Oxide: LiNiMnCoO2. cathode, graphite anode.

​

​

Voltages

 

3.60V, 3.70V nominal; typical operating range 3.0–4.2V/cell, or higher

 

 

Specific energy (capacity)

 

150–220Wh/kg

 

 

Charge (C-rate)

 

0.7–1C, charges to 4.20V, some go to 4.30V; 3h charge typical. Charge current above 1C shortens battery life.

 

 

Discharge (C-rate)

 

1C; 2C possible on some cells; 2.50V cut-off

 

 

Cycle life

 

1000–2000 (related to depth of discharge, temperature)

 

 

Thermal runaway

 

210°C (410°F) typical. High charge promotes thermal runaway

 

​

Applications

 

E-bikes, medical devices, EVs, industrial

 

 

Comments

 

Provides high capacity and high power. Serves as Hybrid Cell. Favorite chemistry for many uses; market share is increasing. Leading system; dominant cathode chemistry.
