 This paper proposes a new method for constructing all solid-state thin film batteries using a lithium-sulfur system. The proposed method uses a vertical graphene nanosheet lithium-sulfur composite thin film cathode, lithium-phosphorus oxinotride thin film solid electrolyte, and a lithium-metal anode. This combination allows for the elimination of the polysulfide shuttling effect, which can cause degradation in other types of batteries. Additionally, the use of a solid-state lithium-sulfur system provides an unlimited source of lithium, allowing for longer cycle life and higher temperatures. The results show that the all-solid-state thin film battery has a capacity retention of 81%, and a high coulombic efficiency of 99.71%.
