Lead tab for bonding to electrode tab and all-solid-state battery including structure having a lead tab bonded to electrode tab

Abstract

By bonding a lead tab of a specific material to electrode tabs with low welding energy, the problem of detachment of a negative electrode protective layer can be solved, and also, in an all-solid-state battery comprising the lead tab bonded to the electrode tabs, the electrolyte and lead tab do not contact each other thus not inducing a lithiation reaction, the lead tab for bonding to electrode tabs and all-solid-state battery comprising the lead tab bonded to the electrode tabs. The lead tab for bonding to electrode tabs forms a bonding portion by bonding with the electrode tabs of the electrode assembly for all-solid-state battery, in which the lead included in the bonding portion contains aluminum.
