Synthesis of Mn(OH)(OCH3) as a Novel Precursor for 2D MnS‐Based Lithium‐ and Sodium‐Ion Battery Anode Materials**
Abstract Manganese sulfides (MnS) are particularly appealing electrode candidates for lithium/sodium‐ion batteries, because of their low cost, wide availability, and environmental benignity. Herein, well‐defined Mn(OH)(OCH3) nanoflakes are synthesized for the first time, whereby two‐dimensional (2D)...

| description | Abstract Manganese sulfides (MnS) are particularly appealing electrode candidates for lithium/sodium‐ion batteries, because of their low cost, wide availability, and environmental benignity. Herein, well‐defined Mn(OH)(OCH3) nanoflakes are synthesized for the first time, whereby two‐dimensional (2D) porous α‐MnS and its composite with N, S co‐doped carbon (α‐MnS@NSC) are produced via the topologic sulfurization of Mn(OH)(OCH3) or a Mn(OH)(OCH3)@polydopamine intermediate. The electrochemical lithium/sodium‐storage properties of α‐MnS are most likely governed by the conductivity, and thus can be significantly enhanced through integrating with conductive carbon coating. As a result, α‐MnS@NSC outperforms the bare α‐MnS and most of the reported MnS‐based anodes, demonstrating the high reversible capacities (1275 mA h g−1 at 0.2 A g−1 for LIBs and 581 mA h g−1 at 0.1 A g−1 for SIBs), great rate capability, and long cyclabilities. This work showcases both a novel strategy to fabricate 2D manganese‐based compounds and a preferred architecture for high performance lithium/sodium‐ion batteries. |
