Patent ID: 8124269

Claim:
A secondary battery for an electronic appliance and configured to be accommodated in the electronic appliance, thereby providing electric power to the electronic appliance, the secondary battery comprising: a battery cell in which a positive electrode, a negative electrode and an electrolyte are accommodated in a pack, and a positive electrode terminal and a negative electrode terminal from the positive electrode and the negative electrode, respectively, extend from a same side face of the pack; a metallic battery can including an opening configured to receive the battery cell and which metallic battery can accommodates the battery cell therein such that the same side face, from which the positive electrode terminal and the negative electrode terminal extend, faces towards the opening side; and a lid comprising a synthetic resin in which a positive electrode terminal part and a negative electrode terminal part configured to be connected to electrodes of the electronic appliance and facing outwardly relative to the lid are provided and which lid plugs the opening of the battery can, wherein the lid includes a substrate including a positive electrode terminal board and a negative electrode terminal board formed on one face thereon and including a positive electrode terminal part as connected to the positive electrode terminal board and a negative electrode terminal part as connected to the negative electrode terminal board formed on the other face thereof, and a top cover which is provided with terminal holes from which the positive electrode terminal part and the negative electrode terminal part are faced outwardly, a positive electrode tab is welded to the positive electrode terminal in one end thereof and to the positive electrode terminal board in the other end thereof, and a negative electrode tab is welded to the negative electrode terminal in one end thereof and to the negative electrode terminal board in the other end thereof, wherein an insulation paper is adhered to a joining part connecting the positive electrode terminal and the negative electrode terminal and the positive electrode tab and the negative electrode tab.
