Abstract

The present invention relates to a polymer battery cell and an electronic device comprising same capable of increasing cell capacity and effectively protecting a protection circuit apparatus from the external environment by utilizing space effectively by means of an effective arrangement of the protection circuit apparatus, the polymer battery cell comprising: an electrode body comprising a cathode plate and an anode plate having a separator interposed therebetween; a cell tab comprising a cathode tab connected to the cathode plate to extend and protrude therefrom, and an anode tab connected to the anode plate to extend and protrude therefrom; and a battery protection circuit module electrically connected to the cell tab. Furthermore, the polymer battery cell is provided with a pouch, made of a flexible material, for accommodating therein the electrode body, the cell tab and the battery protection circuit module.

Description

technical field [0001] The present invention relates to a polymer battery unit and an electronic device including the battery unit, more specifically, to a polymer battery unit with a battery protection circuit module and an electronic device including the battery unit. Background technique [0002] Unlike primary batteries that cannot be charged, secondary batteries are batteries that can be charged and discharged. Secondary batteries are used in small mobile devices such as cellular phones, laptop computers, and camcoders, or medium and large devices such as electric vehicles, hybrid electric vehicles, electric bicycles, and uninterruptible power supplies energy. [0003] A typical secondary battery is a lithium secondary battery. Lithium secondary batteries can be classified into cylindrical and angular can-shaped secondary batteries and flexible pouch-packed secondary batteries according to the shape of a case housing an electrode assembly. Secondary batteries can be ...
