Abstract
A microbattery has a support having a front face, a rear face, first and second current collectors arranged on the front face. A stack including a cathode and an anode separated by an electrolyte is arranged on the current collectors. The anode and cathode respectively contact the first and second current collectors. A protective layer covers the stack. The microbattery has connections in contact with the first and second current collectors, passing through the support from the front face to the rear face. The stack substantially covers of the front face of the support. A method for producing the mircobattery includes etching cavities, in the front face of the support, having a depth that is smaller than the thickness of the support, filing of the cavities with a conducting material and removing a layer of the rear face of the support to uncover the conducting material in the cavities.
