A method for producing lithium-ion batteries (3) comprising the following steps: • (a) forming, on a substrate, a cathode current collector layer (22) and a stack of a cathode layer (23) made from a material capable of inserting lithium ions, an electrolyte layer (24) and an anode layer (25), • (b) depositing a lithium layer on the anode layer (25) in order to form a lithium alloy, • (c) short-circuiting the anode and cathode layers by depositing an anode current collector layer (26) on the anode layer, this short-circuiting causing the diffusion of the lithium ions from the anode layer (25) to the cathode layer (23) and • (d) separating the batteries, resulting in the opening of the short-circuit between the anode and cathode layers in all the batteries. The present method therefore aims to simplify and improve the method for producing lithium-ion microbatteries and, in particular, to simplify and improve the diffusion of the lithium ions from the anode layer (48) to the cathode layer (42) after short-circuiting these two layers (42, 48). |
