All-Solid-State Thin Film Lithium-ion Battery with High Ionic Conductivity Material LiNbO₃ as Anode

An all-solid-state thin film lithium-ion battery (TFLIB) with LiNbO3 (LNO) thin film as the anode for the first time. The LNO-anode TFLIB has excellent properties, including high capacity, small polarization, prominent rate performance, and good cycling performance. In addition, the ionic conductivity of the LNO film prepared in this paper can be as high as 5e(-8) S cm(-1). These results expand the application of LNOs in the field of all-solid-state battery.
