Abstract

A novel cathode Li-supplement additive, Li₄SiO₄@rGO, has been developed; it features high capacity (820 mA h g^-1), high air stability, and feasible Li-supplement potential (4.3 V). Its integration in NCM622‖graphite improves the energy density by 9% and enhances the capacity retention from 27.5% to 70%. Analogous improvements are also manifested in LFP‖graphite.
