Safer lithium-ion battery anode based on Ti3C2Tz MXene with thermal safety mechanistic elucidation

Thermal safety concerns of lithium ion batteries (LIBs) need to be solved urgently to facilitate their large-scale applications. Introducing safer anode materials can suppress the thermal runaway initiation but is usually compromising the cell performance due to their induced lower energy density. In this work, Ti3C2Tz MXene with tailored surface terminating groups is identified to be a safer LIB anode with improved capacity and lower...
