Abstract:
1. A battery packaging method comprising: (a) depositing a plurality of battery component films on the surface of a substrate to form a battery comprising at least one battery cell, the battery cell comprising a plurality of electrodes about an electrolyte, and the battery having at least one open peripheral side surface; (b) providing a thermoplastic bead at an open peripheral side surface of the battery; (c) placing a cap over the battery and in contact with the thermoplastic bead; (d) locally heating the thermoplastic bead by directing an energy beam onto the thermoplastic bead, the energy beam having a beam width sized sufficiently small to heat a beam incident region on the thermoplastic bead substantially without heating adjacent regions; and (e) while the thermoplastic bead is heated by the energy beam, applying a pressure of from about 0.1 psi to about 60 psi to the cap or substrate to more securely bond the thermoplastic bead to the substrate or cap.
