Abstract
The disclosure relates to microbattery devices and assemblies. In an embodiment, a device includes a plurality of microbatteries, a first flexible encapsulation film, and a second flexible encapsulation film. Each of the microbatteries includes a first contact terminal and a second contact terminal spaced apart from one another. The first flexible encapsulation film includes a first conductive layer electrically coupled to the first contact terminal of each of the microbatteries, and a first insulating layer on the first conductive layer. The second flexible encapsulation film includes a second conductive layer electrically coupled to the second contact terminal of each of the microbatteries, and a second insulating layer on the second conductive layer.
