SiO Enabled by ZSM‐5 and Graphene as Long‐Cycle and High‐Rate Anodes for Lithium‐Ion Batteries

Abstract Silicon oxides (SiO, SiO 2 ) with high theoretical capacity and low cost are viewed as promising anodes for the next‐generation lithium‐ion batteries (LIBs) but suffer from inferior rate capability and coulombic efficiency (CE) owing to the sluggish charge transfer kinetics. Herein, the study proposes a multichannel modulation strategy induced by ZSM‐5 and SiO as well as electron‐rich graphene to effectively solve the above issue. Specially, the ZSM‐5, which can not only provide a certain Li + reserve capacity as an anode material, but also serve as a bridge to connect the isolated SiO nanoparticles, providing Li + transport channel and adjusting the transfer kinetic, making it to achieve two things at one stroke, so that the as‐obtained SiO@ZSM@Gra composite shows improved rate performance and CE compared to that of single silicon oxides. Combing with the CV and EIS fitting analysis, it is demonstrated that the constructed composites own higher Li + diffusion coefficient and more charge conduction capability. Furthermore, the fabricated full cell with LiNi 0.8 Co 0.1 Mn 0.1 O 2 exhibits good electro‐chemical properties. The proposed strategy for intrinsic accelerating charge transfer can be conductive to electrode design for the next‐generation low cost and high energy LIBs.
