Synergistically boosting the zinc-ion storage capability of MoSe2 via multiple molecular engineering strategies

摘要：

MoSe₂凭借其良好的稳定性与结构可调性成为锌离子电池正极材料的有利候选之一，然而其较窄的层间距及相对较差的导电性限制了在锌离子电池中的进一步应用.通过简单的溶剂热法制备出了含有1T相的空心球状MoSe₂正极材料.得益于相工程策略与结构工程策略等双重分子工程策略的协同运用，制备的1T空心MoSe正极在0.10A·g^-1的电流密度下表现出127.5mAh·g^-1的比容量.循环100圈后仍能维持90.5 mAh·g^-1的比容量.相比于未改性的MoSe2正极，1T空心MoSe₂正极表现出了显著提升的储锌性能与循环性能，为MoSe₂基正极在锌离子电池中的进一步应用提供了可行策略.

MoSea₂ posesses great potential in serving as cathode material for zinc-ion batteries owing to its favorable stability and structural tunability, while its comparatively narrow interlayer distance and poor conductivity limit its further appli-cations. Herein, the hollow spherical MoSe₂ with high ratio of 1T phase was fabricated via a facile solvothermal method. By virtue of the synergistic effect of phase engineering and structural engineering strategies, the proposed 1T hollow MoSe₂ nano-sphere delivers a high capacity of 127.5 mAh·g^-1 at 0.10 A·g^-1, and maintains a favorable capacity of 90.5 mAh·g^-1 after 100 cycles, Compared to the pristine MoSe2. the proposed 1T hollow MoSe₂ nanosphere presents the significantly improved zinc-ion storage capability and cycling performance, thus providing an effective way to promote the potentials of MoSea₂-based cathodes in zinc-ion batteries.
