Estimating the term…
An electric battery including a microbattery provided with first and second current collectors and an encapsulation device including an electrically-conductive and sealing layer formed by a matrix made of polymer material including electrically-conductive particles. First and second connection pads made of electrically-conductive material are respectively electrically connected to the first and second current collectors of the microbattery. The encapsulation device also includes an additional microbattery provided with first and second current collectors, arranged opposite to and separate from the microbattery by the sealing layer. The first and/or second current collectors of the additional microbattery are electrically connected, respectively, to the first and/or second connection pads via at least a portion of the electrically-conductive particles.
Electric battery comprising:
Method of manufacturing an electric battery comprising a step of encapsulating a microbattery provided with first and second current collectors by arranging opposite thereto and by pressing an additional microbattery provided with first and second current collectors with said microbattery previously provided with first and second connection pads and covered with an electrically-insulating and sealing layer, formed by a polymer material matrix comprising electrically-conductive particles, to obtain an electric connection between the first and/or second connection pads of the microbattery and respectively the first and/or second current collectors of said additional microbattery via a portion of the electrically-conductive particles, and wherein the electric connection is provided by locally compressing the electrically-insulating and sealing layer between the first and/or second connection pads of the microbattery and respectively the first and/or second current collectors of said additional microbattery, thereby transforming a portion of the electrically-insulating and sealing layer from an electrically insulating state to an electrically conductive state.
