Abstract:
1. Method for producing a lithium microbattery successively comprising formation of first and second current collectors, of a cathode, of an electrolyte comprising a lithiated compound and of an anode comprising lithium on a substrate, wherein the electrolyte formation step comprises at least the following successive operations: deposition of an electrolytic thin layer on the substrate provided with the current collectors and with the cathode, deposition, on the electrolytic thin layer, of a first protective thin layer that is chemically inert with regard to lithium, and then of a first masking thin layer, fabrication of a mask by photolithography on the first masking thin layer, selective etching of the first masking thin layer then removal of the mask, selective etching of the first protective thin layer and of the electrolytic thin layer so as to form the electrolyte in the electrolytic thin layer, and removal of the first protective thin layer and of the first masking thin layer.
