METHOD FOR THE TREATMENT OF ELECTRODE TAPS OF STACKED LITHIUM SECONDARY BATTERY IN WHICH THE ELECTORDE TAPS AND LEAD LINE ARE CO-ATTACHED BY RIVET

摘要

Arranging a plurality of positive electrode plates and negative electrode plates with tabs formed on one side on the separator, and sequentially folding them to obtain a laminate in which the positive electrode tabs and the negative electrode tabs overlap each other independently. There is provided a method of processing an electrode tab of a stacked lithium secondary battery, comprising: arranging on the tab, bonding the lead wires and tabs by rivets, and bending the riveted tabs and lead wires to complete the cell. The electrode tab treatment method can significantly reduce the time required for the bonding process by joining the lead wire and the tab by rivets, and does not require a step of removing foreign substances such as an electrode active material present in the tab. In addition, bonding to the positive electrode tab and the negative electrode tab can be performed at the same time.;Lithium Secondary Battery, Electrode Tab, Lead Wire, Rivet
