    摘要: The invention relates to a microbattery comprising through-connections and to the production method thereof. The inventive microbattery comprises a support (1) having a front face (2) and a rear face (3) and first (4) and second (5) current collectors which are disposed on the front face (2) of the support (1). A stack comprising a cathode (8) and an anode (6) which are separated by an electrolyte (7) is disposed on the current collectors (4 and 5). The anode (6) and the cathode (8) are in contact with the first (4) and second (5) current collectors respectively. The aforementioned stack is covered with a protective layer (9). In addition, the microbattery comprises connections (10) which pass through the support (1) from the front face (2) to the rear face (3) thereof and which are in contact with the first (4) and second (5) current collectors. The stack preferably covers essentially all of the front face (2) of the support (1). The invention also relates to a method of producing the microbattery, which comprises: the etching of cavities in the front face (2) of the support (1), said cavities having a depth less than the thickness of the support (1); the filling of the cavities with a conductive material; and the removal of a layer of the rear face (3) from the support (1), in order to reveal the conductive material contained in the cavities.
