Lithium cobalt oxide vs NMC cathode
NMC cathode displaced Lithium cobalt oxide, and 1 measured property shows why — density most clearly.
Lithium cobalt oxide vs NMC cathode
Lithium cobalt oxide
LiCoO2
The cathode that made the lithium-ion cell possible in 1980, still in the phone in your pocket, and abandoned everywhere the pack is large.
NMC cathode
LiNiMnCoO2
Nickel, manganese and cobalt in a layered oxide — the high-energy cathode, and a family whose whole recent history is trying to use less cobalt.
| Property | Lithium cobalt oxide | NMC cathode |
|---|---|---|
| Crystal system Categorical values can be listed side by side but not ordered or subtracted. | trigonal | trigonal |
| Density | 5.1 g/cm³ higher | 4.6–4.8 g/cm³ |
| Molar mass Only one of the two has a figure we can stand behind, so there is nothing to compare. | 97.87 g/mol | Not known |
