Progress of capacity fading mechanisms for lithium-ion batteries

Capacity fading was the main problem of Lithium-ion batteries during the charge-discharge progress. Overcharging, growth of the SEI film, decomposition of the electrolyte, dissolution and phase transition of active materials, and so on were the reasons of capacity fading.Progress of study on capacity fading of Li-ion batteries was summarized. Fading mechanisms were discussed in detail.
