Abstract

The invention relates to a method for operating a battery cell (10), in particular a lithium-ion battery cell, having at least one wound or stacked electrode assembly (28) arranged in a housing, said electrode assembly comprising a first electrode layer (12), at least one separator layer (16) and a second electrode layer (14), and a non-aqueous electrolyte containing one or more solvents and one or more conductive salts. When the battery cell (10) reaches a critical state, a chemical substance or a chemical substance mixture (46) is released, which forms complexes with the lithium ions (22) in the electrolyte (26).
