Electrochemical Performance of Titanium Hydride for Bulk-Type All-Solid-State Lithium-Ion Batteries

TiH 2 was utilized as a negative electrode material for lithium ion battery by using LiBH 4 solid electrolyte.High reversibility of the TiH 2 conversion reaction was successfully obtained in this work.The favorable electrochemical properties of TiH 2 electrode such as robust cyclic and rate performances were reported for the first time, which are superior to the previous report by means of conventional organic liquid electrolyte system.It can be considered as a promising candidate as negative electrode for lithium-ion batteries.
