The universality applications of MoS2@MnS heterojunction hollow microspheres for univalence organic or multivalence aqueous electrolyte energy storage device

Considering the diversified demand of energy field, universal electrode materials for battery system should be developed urgently. Accordingly, we prepared a graded metal-phase MoS2@MnS heterojunction hollow microspheres and studied its application in sodium and zinc storage device. The unique hierarchical hollow structure can protect the active materials from agglomeration, provide buffer volume changes during charging and discharging, and greatly enhance the store ions ability. Moreover, the large layer spacing of MoS2@MnS crystal facilitates the fast intercalation of metal ions. Its specific capacity can reach 606.5 mAh g−1 even after 100 cycles at 100 mA g−1, and the specific discharge capacity remains at 410.4 mAh g−1 after 300 cycles at 1000 mA g−1 with sodium ion battery as anode material. An initial reversible ratio capacity of 340.1 mAh g−1 was achieved at 100 mA g−1 for water system zinc ion battery cathode. The results were far higher than the currently reported capacity of the MoS2 base material. The universality and high-capacity storage materials reported in this work can be widely used in the energy field. •MoS2@MnS hollow microspheres is prepared for sodium and zinc storage device.•Large layer spacing of MoS2@MnS facilitates the fast intercalation of metal ions.•The universality and high-capacity materials can be widely used in energy field.
