CURRENT COLLECTOR TAB FOR SOLID-STATE BATTERIES, CURRENT COLLECTOR, AND ELECTRODE SHEET

Abstract:

Provided are: a current collector tab for solid-state batteries that minimizes the occurrence of cracks in an electrode active material and that makes it possible to minimize peeling within an electrode sheet or interlayer peeling in a layered body of an electrode and a solid electrolyte; a current collector; and an electrode sheet. A stress relaxation section is provided to a current collector tab for a positive electrode sheet or a negative electrode sheet. Specifically, the current collector tab for solid-state batteries comprises a stress relaxation section in a bent area occurring when a plurality of the current collector tabs are bundled in a solid-state battery cell.
