Abstract:
Disclosed herein is a cap assembly mold mounted to a battery cell, in which an electrode assembly including cathodes/separators/anodes is disposed, wherein the cap assembly mold is manufactured by integrally forming a protection circuit board, a safety element, connection terminals, and a cap housing by insert injection molding, and, when the insert injection molding is carried out, the connection terminals are partially exposed from the lower end surface of the cap assembly mold such that the connection terminals can be electrically connected to electrode terminals of the battery cell. According to the present invention, the cap assembly mold is formed by insert injection molding in the state that the protection circuit and the battery are not connected with each other. Consequently, the molding process is carried out using normally available resins, the cap assembly mold is electrically stable, the coating process for preventing electrical short circuits is not necessary, and the possibility of electrical damage to the protection circuit is eliminated.
Abstract:
Disclosed herein is a secondary battery pack including a battery cell having a pair of coupling grooves, each of the coupling grooves having a predetermined depth, an insulative mounting member mounted to the top of the battery cell, a protection circuit module (PCM) having a pair of connection coupling members protruding downward, and an insulative cap coupled to the top of the battery cell, wherein the connection coupling members are inserted into coupling grooves formed at electrode terminals of the battery cell through openings of the insulative mounting member in a state in which the insulative mounting member is mounted to the top of the battery cell, thereby achieving the coupling of the PCM to the battery cell and the insulative mounting member and the electrical connection between the battery cell and the PCM.
