Developing efficient energy conversion and storage technology is gradually becoming more and more necessary with the increasing shortage of fuel resources and the growth of environmental pollution. Demand and applications for the emerging technology such as new-energy vehicles and massive-scale energy storage are also expanding. Therefore, new rechargeable batteries, especially the most promising electrochemical energy storage device, lithium-ion batteries (LIBs), play an important role on the energy storage stage. LIBs have achieved large-scale industrialization, while the various non-negligible problems still exist compared with the demand for the future. Significantly, most electrochemical reactions occur on the electrode-electrolyte interface, and interface components, surface structure and property determine the performance of batteries. Thus, numerous efforts have been made to form or modify the electrode-electrolyte interface. This article reviews recent research about surfaceinterface modification in electrodes and organic liquid electrolytes in LIBs. Specifically, the basic growth mechanism of electrolyte-electrode interface and SEI layer is referred. The summary and discussion of surface modification and the innovative design of SEI layer are mainly focused on. Finally, future research directions focusing on electrode-electrolyte interface for lithium storage are proposed.
