Abstract
A lithium microbattery formed by a stack of thin layers on a substrate which comprises two current collectors, a positive electrode, a solid electrolyte layer, a negative electrode and an encapsulating layer. The encapsulating layer is formed by a protective layer made from polymer material on which a barrier layer is arranged. The protective layer comprises a copolymer formed from a homogeneous mixture of at least two photopolymerizable precursor materials, respectively acrylate-based and epoxide-based.
