CONNECTION METHOD OF POSITIVE AND NEGATIVE TERMINALS OF LITHIUM BATTERY

摘要

PURPOSE: A method for connecting the positive and negative terminals of a lithium battery is provided, to increase the welding strength by widening the welding area and to reduce the processing step. CONSTITUTION: The method comprises the steps of allowing the short part of a terminal piece(30) connected with a lithium battery element(20) to be exposed outside a case(10); inserting a header(40) on the upper part of the case(10) and fixing it; and fixing the case(10) and the header(40) together with the terminal piece(30) by welding.
