Abstract

The invention relates to a microbattery that comprises a stack on a substrate, covered by an encapsulation layer and comprising first and second current collector/electrode assemblies, a solid electrolyte and electrical connections of the second current collector/electrode assembly to an external electrical load. The electrical connections are formed by at least two electrically conductive barriers passing through the encapsulation layer from an inner surface to an outer surface of the encapsulation layer. Each of the barriers has a lower wall in direct contact with a front surface of the second current collector/electrode assembly and an upper wall opening onto the outer surface of the encapsulation layer. The barriers form a compartmentalization network within the encapsulation layer.
