The lithium battery pack is usually composed of a plastic shell, a protective plate, an electric cell, an output electrode, a connecting contact piece, and other insulating tape, double-sided tape, etc.

　　Lithium battery cell: the core part of finished battery

　　Protection board: It has the functions of over charging, over discharging, over current, short circuit, NTC temperature control intelligent protection, etc.

　　Plastic shell: support frame of the whole battery; Positioning and fixation of the protection plate; Carry and limit all other non shell parts.
