Negative electrodes for Li-ion batteries
The active materials in the electrodes of commercial Li-ion batteries are usually graphitized carbons in the negative electrode and LiCoO 2 in the positive electrode. The electrolyte contains LiPF 6 and solvents that consist of mixtures of cyclic and linear carbonates. Electrochemical intercalation is difficult with graphitized carbon in LiClO 4 /propylene
