S/Li 2 S phase separation at nanoscale is observed for the first time in the solid‐state Li–S battery by using in situ transmission electron microscopy. This nanophase separation not only reduces the diffusion distance but also provides the S/Li 2 S interfaces network, which is favorable for electron and Li + ion transportation during the lithiation process.
