Thin solid membranes are formed by a new strategy, whereby an in situ derived self‐healing polymer matrix that penetrates the void space of an inorganic solid is created. The concept is applied as a separator in an all‐solid‐state battery with an FeS 2 ‐based cathode and achieves tremendous performance for over 200 cycles. Processing in dry conditions represents a paradigm shift for incorporating high active‐material mass loadings into mixed‐matrix membranes.
