Lithium cobalt oxide (LCO) |
LiCoO2 |
LixC6 → xLi++xe-+C6 |
Li1-xCoO2+xLi++xe-→LiCoO2 |
C6+ LiCoO2 ↔ LiC6+CoO2 |
|
2 |
Lithium manganese oxide (LMO) |
LiMn2O4 |
LixC6 → xLi++xe-+C6 |
Li1-xMn2O4+xLi++xe-→ LiMn2O4 |
C6+LiMn2O4 ↔ LiC6+Mn2O4 |
|
3 |
Lithium nickel cobalt aluminium oxide (NCA) |
LiNiCoAlO2 |
LixC6 → xLi++xe-+C6 |
Li1-x NiCoAlO2+xLi++xe-→ LiNiCoAlO2 |
C6+LiNiCoAlO2 ↔ LiC6+NiCoAlO2 |
|
4 |
Lithium nickel cobalt manganese oxide (NMC) |
LiNi0.8Mn0.1Co0.1O2 |
LixC6 → xLi++xe-+C6 |
Li1-xNi0.8Mn0.1Co0.1O2+ xLi++xe-→ LiNi0.8Mn0.1Co0.1O2 |
C6+LiNi0.8Mn0.1Co0.1O2 ↔ LiC6+Ni0.8Mn0.1Co0.1O2 |
|
5 |
Lithium iron phosphate (LFP) |
LiFePO4 |
LixC6 → xLi++xe-+C6 |
Li1-xFePO4+xLi++xe-→ LiFePO4 |
C6+LiFePO4 ↔ LiC6+FePO4 |
|

|
Lithium titanium oxide (LTO) |
Li4Ti5O12 |
Li4Ti5O12 → Ti5O12+4Li++4e- |
4Li1-xMn2O4+4Li++4e- → 4LiMn2O4 |
Li4Ti5O12+4Mn2O4 ↔ 4LiMn2O4+Ti5O12 |
