NOVELTY - The battery has a protective circuit board (200) electrically connected to a bare cell (100). Multiple lead plates (300) are bent such that the bare cell is coupled with the protective circuit board in parallel. A cathode lead plate (320) of each lead plate is connected to the bare cell, and an anode lead plate (310) of each lead plate is arranged on an outer surface of the protective circuit board opposite to an inner surface of the protective circuit board facing the bare cell. An insulation filling member is placed on a cap plate (132). A combining case covers an upper end of the bare cell.    USE - Rechargeable battery e.g. lithium ion battery, for use as a power source for an electronic device such as communication device, information processing device and multimedia device. Uses include but are not limited to liquid electrolyte lithium ion battery, solid polymer electrolyte/gel state electrolyte lithium ion battery, can type lithium ion battery and pouch type lithium ion battery.    ADVANTAGE - The plates of the lead plate are bent around an inside bending part at about 180 degrees such that the bare cell is coupled with the protective circuit board. The distance between the bare cell and the protective circuit is reduced by changing shape and structure of the lead plate, thus increasing capacity per volume of the battery. The manufacturing process of the battery is simplified with high productivity by using a combining case. The battery prevents possibility of a short circuit caused by contacting the mold, and explosion due to molding and deformation during bending process. The insulation filling member is installed on the cap plate so as to enhance the insulation between the cap plate and the protective circuit board. The battery prevents deformation of the protective circuit board by preventing the protective circuit board from being pressurized by the combining case.
