MICROBATTERY AND METHOD FOR MANUFACTURING SAME

摘要

The invention relates to a microbattery comprising a stack (17) on a substrate (2), covered by an encapsulation layer (18) and comprising first and second collector/electrode assemblies (19, 21), a solid electrolyte (20) and means (25) for electrically connecting the second collector/electrode assembly (21) to an external electrical load. The electrical connection means (25) consist of at least two electrically conductive barriers passing through the encapsulation layer (18) from an inner surface (23) to an outer surface (30) of the encapsulation layer (18). Each of the barriers has a lower wall (31) in direct contact with a front face (22) of the second collector/electrode assembly (21) and an upper wall (32) opening onto the outer surface (30) of the encapsulation layer (18). The barriers form a compartmentalization network (40) within the encapsulation layer (18).
