Abstract
An imidazolidinylide compound for use as a shut-down additive for a lithium-ion battery. The imidazolidinylide compound has a formula (I), wherein, R1 to R4, each independently the other, is a linear C1- to C16-alkyl group, a branched C1- to C16-alkyl group, a C2- to C16-alkenyl group, a C3- to C8-cycloalkyl group, or a C3- to C16-arene group, wherein at least one of R2 and R3 may also be H, R1 to R4, each independently of the other, is completely, partially or not fluorinated, and R1 to R3 may each also contain O as a heteroatom.
