TERMINAL STRUCTURE FOR SMALL LITHIUM BATTERY AND MANUFACTURING METHOD THEREOF AND LITHIUM BATTERY COMPRISING THE TERMINAL STRUCTURE

摘要

PURPOSE: A terminal structure for a small lithium battery is provided to ensure excellent insulating property and airtightness by welding and sealing a negative electrode structure and a positive electrode wire by glass and to be used for a battery requiring long-term preservation and size limit. CONSTITUTION: A terminal structure for a small lithium battery comprises: a positive electrode wire(110); a thin-plate type current collector(150) which is vertically bonded with an end part(112) of the positive electrode wire; and a negative electrode structure(120) which is adjacent to the end part and has holes passing through the positive electrode wire(110) at the center thereof, and in which molded glass(130) is inserted in a space formed by the gap from the positive electrode wire.
