Sulfuretted Li- and Mn-Rich Cathode Material with Epitaxial Spinel Stabilizer for Ultra-Long Cycle Li-Ion Battery

•Sulfuretted Li- and Mn-Rich cathode material with epitaxial spinel stabilizer is successfully constructed.•The introduced spinel phase stabilizer was lattice-compatible with Li- and Mn-Rich.•S incorporation can effectively accelerate the lithium ions diffusion and suppress the undesired oxygen redox.•The electrochemical performance was greatly improved by epitaxial spinel and S doping.
