文摘

S/Li₂S 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/Li₂S interfaces network, which is favorable for electron and Li⁺ ion transportation during the lithiation process.
