A universal anode material of 1D core-shell MoO₂@MoS₂/nitrogen-doped carbon (MoO₂@MoS₂/NC) nanorods has been elaborately synthesized via a facile fabrication route for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), in which MoO₂ core not only acts as a conductive backbone for efficient electron transport, but creates structural disorders in MoS₂ nanosheets to prevent aggregation and expose more active sites for alkali-ions. Meanwhile, the MoO₂ core is tightly encapsulated by the parallelly aligned MoS₂ nanosheets to constrain the size of crystals, which greatly shortens the ionic diffusion path and accelerates diffusion rate, thus ensuring fast reaction kinetics. Additionally, the resilient and conductive N-doped carbon matrix in the hybrid could maintain the structural integrity and enhance the electrical conductivity of the electrodes, improving the rate capability and life span. The flexible 1D nanorods could contract freely during the charge/discharge process, further assuring the structural stability of the electrodes. Benefiting from the above-mentioned advantages, the MoO₂@MoS₂/NC electrodes still remains a specific capacity of 583.5 mA h g^-1 after 1500 cycles at a high current density up to 10 A g^-1 in LIBs, and a capacity of 419.8 mA h g^-1 is steadily kept over 800 cycles at 2 A g^-1 in SIBs.

通过锂离子电池（LIBs）和钠离子的简便制备途径，精心合成了一维核壳型MoO ₂ @MoS ₂ /氮掺杂碳（MoO ₂ @MoS ₂ / NC）纳米棒的通用阳极材料。电池（SIB），其中MoO ₂核不仅充当有效电子传输的导电主链，而且在MoS ₂纳米片中造成结构紊乱，以防止聚集并暴露更多的碱金属离子活性位。同时，MoO ₂芯被平行排列的MoS ₂紧密封装纳米片限制了晶体的尺寸，极大地缩短了离子扩散路径并加快了扩散速率，从而确保了快速的反应动力学。此外，混合材料中的弹性导电N掺杂碳基体可以保持结构完整性并增强电极的电导率，从而提高倍率能力和使用寿命。柔性一维纳米棒可在充电/放电过程中自由收缩，从而进一步确保电极的结构稳定性。受益于上述优点，MoO ₂ @MoS ₂ / NC电极经过1500次循环后在高达10 A g ^-1的高电流密度下仍保持583.5 mA hg ^-1的比容量在LIBS，和419.8毫安Hg的容量^-1以2甲克稳步保持超过800次循环^-1中的SIB。
