Hydrangea‐Like Architectures Assembled by MnS Nanoparticles Embedding in N, S Codoped Carbon Framework for Superior Lithium‐Ion Storage

The manipulation of structure stability in high‐capacity manganese sulfide (MnS), which undergoes serious volumetric change during discharge and charge processes, is crucial precondition for enhancing their cycling performance. Herein, a unique hydrangea‐like heterostructure with MnS nanoparticles (NPs) embedding and heteroatom (N, S) codoping (MnS@NSC) is successfully synthesized and explored as the anode material for lithium‐ion batteries (LIBs). The resultant MnS@NSC heterostructure, consisting of encapsulated MnS NPs and porous carbon framework, is endowed with outstanding conductivity, high activity, and alleviated volume expansion. When used as anode for LIBs, the MnS@NSC‐6 electrode delivers a high reversible specific capacity of 1042 mAh g −1 at 0.1 A g −1 after 100 cycles, excellent rate capability, and outstanding long‐term cycling stability (657 mAh g −1 at 2 A g −1 after 1000 cycles), displaying a hopeful practical application of the MnS‐based electrode. This work offers an effective strategy for the rational design of MnS materials with high capacity and superior structure stability.
