  • Electrolytes for lithium rechargeable cells
    Patent number: 6326104
    Abstract: An electrolyte, such as for a lithium rechargeable cell, is described which contains a pyrazolium cation and may also contain a lithium salt. The lithium salt may be at least one of LiBF4, LiAsF6, LiPF6, and LiTF. The electrolyte, when used in an electrochemical cell, has a charge/discharge capacity and charging efficiency that is superior to the same properties of ionic liquid electrolytes without a pyrazolium cation. Electrochemical cells are also described and contain an anode, a cathode, and the pyrazolium cation electrolyte.
