Electric battery and means for encapsulating same

摘要

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.

1. Electric battery comprising:
a microbattery provided with first and second current collectors; first and second connection pads made of electrically-conductive material and respectively electrically connected to the first and second current collectors of said microbattery; a sealing layer, formed by a polymer material matrix comprising a plurality of electrically-conductive particles, the sealing layer being an electrically-insulating layer; and an additional microbattery provided with first and second current collectors, arranged opposite to and separate from said microbattery by the sealing layer; wherein at least a portion of individual particles of the plurality of electrically-conductive particles contact both i) one of the first and second connection pads of the microbattery and ii) a corresponding one of the first and second current collectors of the additional microbattery, thereby electrically connecting the microbattery to the additional microbattery.
