Abstract: The recent development of pre-lithiation technologies in lithium-ion battery, lithium-sulfur battery, lithium-air battery, lithium-ion capacitor and other kind of new energy storage systems were summarized. The pre-lithiation strategies mainly include in-situ lithium-doping, interfacial contact reaction with lithium-metal, electrochemical and chemical lithiation, etc. It can efficiently ameliorate several challenging problems: (i) compensating the initially high irreversible capacity of anode in lithium-ion battery; (ii) solving the lithium consumption and safety issue of metallic lithium anode in lithium-sulfur/air battery; (iii) addressing the anodic lithium compensation in lithium-ion capacitors; thereby giving rise to enhanced electrochemical performances. However, a series of key issues, including the formation of solid electrolyte interface film on the electrode surface, growth of lithium-dendrite, electrolyte decomposition, and electrode internal-heating after the pre-lithiation, may influence on the energy/power density, cycle life and safety of energy storage systems. Full knowledge and understand of their correlations and interaction mechanism is strongly demanded to seek a simplified strategy for an accurate control in lithium compensation and then guarantee its scalable application. Therefore, it is rather significant to retrieve relevant literatures and summarize the pre-lithiation applications in energy storage systems for understanding the progress more comprehensively, thereby providing academic reference and theoretical basis for the further development in relevant and other kind of power system (e.g., sodium battery).
