ENCAPSULATED MICROBATTERY HAVING IMPROVED SEALING AND ENCAPSULATION PROCESS PROVIDING IMPROVED SEALING

摘要

Encapsulated microbattery comprising a microbattery (B) carried by a substrate (2), an encapsulation cover (C1), said encapsulation cover comprising a first face (13) in contact with the microbattery (B) and the substrate (2 ), said first face (13) comprising a central zone (Zc) and a peripheral zone (Zp) surrounding the central zone (Zc), the central zone (Zc) being in contact with the microbattery (2) and the peripheral zone ( Zp) being in contact at least with the substrate (2). The encapsulation cover has cavities (18) in fluid communication with the central zone (Zc) of the first face, and capable of retaining at least one gaseous element generated by the microbattery during its operation.
