A high-voltage, all-solid-state lithium-ion thin-film battery composed of LiNi 0.5 Mn 1.5 O 4 cathode, a LiPON solid electrolyte, and a lithium metal anode has been deposited layer by layer on low-cost stainless-steel current collector substrates.
Controllable engineering of thin lithium (Li) metal is essential for increasing the energy density of solid-state batteries and clarifying the interfacial evolution mechanisms of a lithium metal negative electrode. However, fabricating a thin lithium electrode faces significant challenges due to the fragility and high viscosity of Li metal.
All-solid-state thin film Li-ion batteries (TFLIBs) with an extended cycle life, broad temperature operation range, and minimal self-discharge rate are superior to bulk-type ASSBs and have attracted considerable attention.
Among such batteries, all-solid-state lithium batteries (ASSLBs) assembled with solid electrolytes are promising candidates as next-generation rechargeable batteries owing to their enhanced safety and high energy density , , , , .

Thus, our results demonstrate that the thin, flexible, and ion-conductive cross-linked solid electrolyte sheet in this study can be used as a promising solid electrolyte for all-solid-state lithium batteries with good capacity retention, favorable rate capability, and high energy density because of its low thickness.
