Ambient Temperature and Pressure Mechanochemical Preparation of Nano-LiTiS_2

摘要

Nano-LiTiS_2 is synthesized by mechanochemically milling a stoichiometric mixture of TiS_2 and Li_3N at ambient temperature and pressure. When nano-LiTiS_2 is incorporated into an all-solid-state Li-ion battery configuration, it exhibits a stable discharge capacity of 220 mAh g~(-1) after 60 cycles. Mechanochemical lithiation enables the utilization of otherwise lithium free cathode intercalation materials that would be incompatible in a Li-ion configuration.
