Abstract
A microbattery that includes, in succession starting from a first substrate: a first current collector, a first electrode, an electrolyte, a second electrode consisting of a solder joint, a second current collector and a second substrate. Additionally, a method for manufacturing a microbattery, which includes the following steps: forming a thin-film multilayer including, in succession from the first substrate, a first current collector, a first electrode, an electrolyte and a first metal film; forming a second current collector on a face of a second substrate; and forming a second electrode by soldering the first metal film and the second current collector together, said substrates being placed facing each other during assembly.
