## Description

- description: Molybdenum disulfide (MoS2)-based cathodes have exhibited good electrochemical
    reactions in all phenyl complex (APC) electrolytes. However, APC electrolytes
    are highly corrosive and susceptible to oxidation. Alternatively, magnesium fluorinated
    alkoxyaluminate electrolyte (Mg[Al(HFIP)4]2) is a pioneering chloride-free electrolyte
    with remarkable electrochemical activity in rechargeable Mg batteries (RMBs).
    This study aims to investigate the compatibility of various MoS2 nanomaterials
    with Mg[Al(HFIP)4]2 in RMBs. Seven MoS2 nanomaterials were synthesized under different
    hydro/solvothermal conditions and evaluated as cathode materials in RMBs. The
    results revealed that the electrochemical activity of the as-synthesized MoS2
    in RMBs significantly varied and MoS2 with high content of 1T-phase (M5) exhibited
    the best specific capacity of ca. 35 mAh g−1. Heteroatom doping, graphene oxide
    (GO) incorporation, and dual-salt electrolytes were employed to enhance the electrochemical
    performance of M5. The electrochemical tests showed that all doped-MoS2 and GO-MoS2
    delivered poor specific capacities (< 20 mAh g−1), properly due to the disorder
    of the cathode material and the entrapment of Mg2+ ions. In contrast, dual-salt
    electrolytes (0.3 M Mg[Al(HFIP)4]2/0.3 M LiCl) improved the initial specific capacity
    by 242%. This is attributed to the preferential intercalation of Li+ ions that
    reduces the diffusion energy barrier and facilitates the intercalation of Mg+2
    ions.
