ABSTRACT

ABSTRACT

All-solid-state thin-film lithium batteries (TFBs) with high voltage are crucial for powering microelectronics systems. However, the issues of interfacial instability and poor solid contact of cathode/electrolyte films have limited their application. In this work, the preferentially orientated LiCoO2 (LCO) nanocolumns and the LCO/LiPON/Li TFBs are fabricated by in situ heating sputtering. By introducing the LiF interlayer, the solid contact of the LCO/LiPON interface is improved, enabling the high-voltage TFBs. The elemental diffusion, morphology change, and interfacial deterioration are suppressed, as demonstrated by various in situ and ex situ tests. As a result, the LCO/LiF/LiPON/Li TFB exhibits a more stable and higher capacity compared to other TFBs. This work provides guidance to improve the solid contact of TFBs and increase the performance of all-solid-state lithium batteries.
