In rechargeable Mg batteries, kinetically reasonable and electrolyte‐compatible cathode materials are required to achieve high electrochemical performance. Here, we report a high‐performance rechargeable Mg battery cathode material that is constructed from layered structural MoS₂ nanosheets decorated on conductive nitrogen‐doped carbon nanofibers (N‐CNFs@MoS₂). We demonstrate that N‐CNFs@MoS₂ exhibits good electrochemical compatibility in two types of dual‐salt electrolytes including an all‐phenyl complex with lithium chloride (LiCl‐APC) and bis(trifluoromethane)sulfonimide lithium salt with magnesium chloride (MgCl₂‐LiTFSI). The fabricated N‐CNFs@MoS₂‐Mg batteries based on both dual‐salt electrolyte systems exhibit good cyclic stability and high rate performance.

MoS2-纳米片装饰的碳纳米纤维复合材料可实现用于镁电池的高性能阴极材料

在可充电镁电池中，需要具有动力学上合理且与电解质兼容的阴极材料才能实现高电化学性能。在这里，我们报告了一种高性能的可充电镁电池正极材料，该材料由在导电氮掺杂碳纳米纤维（N-CNFs @ MoS ₂）上装饰的分层结构MoS ₂纳米片构成。我们证明，N-二的CNF @的MoS ₂表现出良好的在两种类型的双盐的电解质，包括用氯化锂（LiCl-APC）和双（三氟甲烷）磺酰亚胺锂盐与氯化镁的所有苯基复杂氯化镁（MgCl电化学相容性₂ - LiTFSI）。伪造的N-CNFs @ MoS ₂基于两种双盐电解质系统的镁电池均具有良好的循环稳定性和高倍率性能。
