説明
<jats:title>Significance</jats:title> <jats:p> We propose a concept of “sulfur-equivalent cathode materials,” and reason that instead of using problematic elemental sulfur, one can use sulfur-containing compounds as the alternatives with a comparable electrochemical property but free of any polysulfide generation. We demonstrate here the great potential of amorphous MoS <jats:sub>3</jats:sub> as such a sulfur-equivalent cathode material for room-temperature Li–S and Na–S batteries. More remarkably, we find that MoS <jats:sub>3</jats:sub> is fully cyclable in the carbonate electrolyte (which is known to kill conventional sulfur cathodes) under a relatively high temperature of 55 °C. MoS <jats:sub>3</jats:sub> can also be used as the cathode material of even more challenging Na–S batteries to enable an impressive performance. </jats:p>
