Apparatus for preventing overcharging of battery and battery comprising the apparatus

A battery provided with an apparatus for preventing overcharging thereof, comprising:

• a plurality of battery cells in face-contact and stacked;
• a plurality of holders interposed on respective gaps between the battery cells to be stacked;
• an installation space formed between borders of adjacent holders;
• a lead tap extended from the cell and exposed extraneously through the installation space;
• a bus bar that forms a contact point together with the lead tap;
• and
• a cutting module which is inserted into the installation space and an inserted end of the cutting module is disposed between the cells adjacent to the inner side of the installation space to be fixed to a holder and an exposed end of the cutting module has a cutter blade directed to a gap between the lead tap and the bus bar bonded together that is formed,
• wherein the gap between the inserted end and the exposed end is connected with a plurality of hinges to compress the hinges to be unfolded when the cell is expanded to a side direction and deploy the exposed end outwardly for the cutter blade to separate the bonding of the lead tap and the bus bar.
