A reaction‐protective separator that slows the growth of lithium dendrites penetrating into the separator is produced by sandwiching silica nanoparticles between two polymer separators. The reaction between lithium dendrites and silica nanoparticles consumes the dendrites and can extend the life of the battery by approximately five times.
