As an efficient and environmental friendly energy storage system, lithium battery has been integrated into daily mobile life [1].Lithium batteries are becoming indispensable to all types of electronic products such as laptop computers, mobile phones, digital cameras [2].A typical lithium battery consists of positive electrode (cathode), negative electrode (anode), electrolyte and other inactive materials (binder, conductive agent, separator) [3].In a working battery, energy storage and release are always accompanied by the transfer of electrons and the transport of ions at the electrode-electrolyte interfaces, including anode-electrolyte interface and cathode-electrolyte interface [4-7].The interfacial charge transfer is related to the de-solvation process, diffusion dynamics and transport pathway of lithium ions, which strongly relies on the structure and composition of the interface [8].Therefore, deeply understanding on electrolyte-electrode interface is of significance for achieving a stable and long-life lithium battery.
