Abstract

The invention relates to a lithium-ion solid-state battery cell with at least one electrode / separator arrangement in which at least one separator (S) is arranged between an anode (A) and a cathode (K), wherein the separator (S) comprises a solid electrolyte. According to the invention, the separator (S) is divided into at least one separator layer (7) in which the solid electrolyte is integrated, and into a thermally activatable sacrificial separator layer (9), which, upon a preferably first thermal activation, releases a liquid electrolyte (E) that spreads into the pores of the electrode material (5) of the anode / cathode (A, K), and which solidifies in the pores of the electrode material (5) upon thermal deactivation.
