英文摘要	Solid-state Li secondary batteries may become high energy density storage devices for the next generation of electric vehicles, depending on the compatibility of electrode materials and suitable solid electrolytes. Specifically, it is a great challenge to obtain a stable interface between these solid electrolytes and cathodes. Herein, this issue can be effectively addressed by constructing a poly(acrylonitrile-co-butadiene) coated layer onto the surface of LiNi0.6Mn0.2Co0.2O2 cathode materials. The polymer layer plays a vital role in working as a protective shell to retard side reaction and ameliorate the contact of the solid-solid interface during the cycling process. In the resultant solid-state batteries, both rate capacity (99 mA h g(-1) at 3 C) and cycling stability (75% capacity retention after 400 cycles) are improved after coating. This impressive performance highlights the great importance of layer modification in the cathode and inspires the development of solid-state batteries toward practical applications.
