Towards thermally stable high performance lithium-ion batteries: the combination of a phosphonium cation ionic liquid and a 3D porous molybdenum disulfide/graphene electrode

Journal Article


Abstract


  • We report a thermally stable high-performance lithium battery using an

    electrochemically synthesized three-dimensional porous molybdenum

    disulfide/graphene composite electrode and a phosphonium-based ionic

    liquid (IL) electrolyte. Benefiting from the structural merits of the chosen

    electrode and the thermal stability of the electrolyte, the cell coupled

    with a Li foil exhibits excellent rate performance and cycling

    capability at room temperature; and that is retained with an even

    better rate capability at an elevated temperature of 50 8C. This work

    may provide a new avenue for the development of safe and high

    performance lithium-ion batteries at high temperature.
