| | Materials | Theoretical capacity
(mA h g−1) | Advantages | Common issues |
| | TiO2 | 330 | Fast lithium ion diffusion; low cost; environmentally friendly; good safety | Low capacity; low electrical conductivity; poor rate capability |
| | Metal oxides (CuO, NiO, Fe3O4, etc.) | 500–1200 | High capacity; high energy; low cost | Low coulombic efficiency; unstable SEI formation; low electrical conductivity; poor capacity retention |
| | Carbon | 372 | Good working potential; low cost;
good safety | Low coulombic efficiency; high irreversible capacity |
| | Si | 4200 | High specific capacities | Large irreversible capacity; poor cycling |
| | Sn | 990 | Good safety; low cost; good electrical conductivity | Poor cycling |
