MICROBATTERY AND METHOD FOR MANUFACTURING A MICROBATTERY

摘要

The invention relates to a microbattery that comprises, in succession starting from a first substrate (2): a first current collector (3), a first electrode (4), an electrolyte (5), a second electrode (11) consisting of a solder joint, a second current collector (7) and a second substrate (8). The invention also relates to a method for manufacturing a microbattery, which comprises the following steps: forming a thin-film multilayer comprising, in succession from the first substrate (2), a first current collector (3), a first electrode (4), an electrolyte (5) and a first metal film; forming a second current collector (7) on a face of a second substrate (8); and forming a second electrode (11) by soldering the first metal film and the second current collector (7) together, said substrates (2, 8) being placed facing each other during assembly.
