Abstract: A thin-film battery of lithium-free type includes a stack of a positive electrode made of LiCoO2, an electrolyte layer made of LiPON, and a negative electrode made of copper. An adhesive layer based on polyvinylidene chloride (PVDC) is positioned on a face of the negative electrode opposite the electrolyte layer.

Abstract: A lithium-metal or lithium-ion battery includes a stack of a cathode layer made of LiCoO2, an anode layer and an electrolyte layer made of LiPON positioned between anode and cathode layers. An encapsulating layer covers the stack. The battery further includes an interface layer made of a material that is able to capture oxygen generated during charge/discharge cycles of the battery. This interface layer is placed under the encapsulating layer.
