| LMO | Lithium Magnese Oxide is a cathode material. At anode Lithium Graphite is used | Lin C6 ↔ Li06C(Graphite) + nLi+ +n e- | Lim-nMnO4 + nLi+ + ne- ↔ LimMn2O4 |
| NCA | Lithium Nickel Cobalt Aluminium Oxide is a cathode material. Lithium Graphite is anode material. | Lin C6 ↔ Li06C(Graphite) + nLi+ +n e- | Lim-n(NixCoyALz)O2 nLi+ ne- ↔ Lim(NixCoyALz)O2 |
| NMC | Lithium Nickel Manganese Cobalt Oxide is a cathode material. Lithium Graphite is anode material. | Lin C6 ↔ Li06C(Graphite) + nLi+ +n e- | Lim-n (NixMnyCoz)O2 + nLi+ + ne- ↔ Lim(NixMnyCoz)O2 |
| LFP | Lithium Iron Phosphate is cathode material. Lithium Graphite is anode material. | Lin C6 ↔ Li06C(Graphite) + nLi+ +n e- | Lim-nFePO4 + nLi+ + ne- ↔ LimFePO4 |
| LCO | Lithium Cobal Oxide is a cathode material. Lithium Graphite is anode material. | Lin C6 ↔Li06C(Graphite) + nLi+ +n e- | Lim-n CoO2(s) + nLi+ + ne ↔ LimC6O2(s) |
