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

TiH2 was utilized as a negative electrode material for lithium ion battery by using LiBH4 solid electrolyte. High reversibility of the TiH2 conversion reaction was successfully obtained in this work. The favorable electrochemical properties of TiH2 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.
