Co-Modification of commercial TiO anode by combining a solid electrolyte with pitch-derived carbon to boost cyclability and rate capabilities.

The bad electrochemical performance circumscribes the application of commercial TiO (c-TiO) anodes in Li-ion batteries. Carbon coating could ameliorate the electronic conductivity of TiO, but the ionic conductivity is still inferior. Herein, a co-modification method was proposed by combining the solid electrolyte of lithium magnesium silicate (LMS) with pitch-derived carbon to concurrently meliorate the electronic and ionic conductivities of c-TiO.
