Hybrid ultrathin NiMoO₄ nanosheets/SnO₂ nanospheres/rGO sheets nanocomposite developed via a versatile fast microwave-assisted hydrothermal method was investigated as feasible anode material for lithium-ion batteries. Synthesized NiMoO₄/SnO₂/rGO phase pure nanocomposite was confirmed by XRD, Raman, FESEM-EDX, XPS and TEM analysis. Lithium ion batteries fabricated using the newly developed hybrid ultrathin NiMoO₄/SnO₂/rGO nanocomposite as an anode material exhibit a high initial discharge capacity of 2128 mAh g⁻¹ and at the 100th cycle is 620 mAh g⁻¹ at a current density of 500 mA g⁻¹. Further, NiMoO₄/SnO₂/rGO nanocomposite exhibits excellent rate capability and much better capacity of 498 mAh g⁻¹ after the 500th cycle at a higher current density of 1000 mA g⁻¹ with a coulombic efficiency of ∼100%. The NiMoO₄/SnO₂/rGO nanocomposite shows better electrochemical performance than pure NiMoO₄ nanosheets and NiMoO₄/SnO₂ nanocomposite and it is attributed to the synergetic effect of NiMoO₄ nanosheets and SnO₂ nanospheres dispersed on rGO sheets, which improves the surface area, electronic conductivity, low particle size and maintains structural integrity.

通过通用的快速微波辅助水热法开发的混合超薄 NiMoO ₄纳米片/SnO ₂纳米球/rGO 片纳米复合材料被研究为可行的锂离子电池负极材料。通过XRD、Raman、FESEM-EDX、XPS和TEM分析证实合成的NiMoO ₄ /SnO ₂ / rGO相纯纳米复合材料。使用新开发的混合超薄 NiMoO ₄ /SnO ₂ / rGO纳米复合材料作为负极材料制造的锂离子电池表现出 2128 mAh g ^-1的高初始放电容量，并且在第 100 次循环时为 620 mAh g ^-1，电流密度为500 mA g ^-1。此外，NiMoO₄ /SnO ₂ /rGO 纳米复合材料在1000 mA g ^-1的较高电流密度下，在第500 次循环后表现出优异的倍率性能和更好的498 mAh g ^-1容量，库仑效率约为100%。NiMoO ₄ /SnO ₂ / rGO纳米复合材料比纯 NiMoO ₄纳米片和 NiMoO ₄ /SnO ₂纳米复合材料表现出更好的电化学性能，这归因于 NiMoO ₄纳米片和分散在rGO片上的 SnO ₂纳米球的协同作用，改善了表面面积、电子导电性、低粒径并保持结构完整性。
