  • Patent number: 11502335
    Abstract: Provided are an electrolyte for a non-aqueous electrolyte battery using a positive electrode including nickel, where the battery generates a small amount of gas during a durability test even if the cell potential reaches 4.1 V or more, as well as a non-aqueous electrolyte battery using the electrolyte. In the electrolyte for a non-aqueous electrolyte battery including a positive electrode including at least one selected from the group consisting of oxides containing nickel and phosphates containing nickel as a positive electrode active material, the electrolyte comprises (I) a non-aqueous organic solvent, (II) a fluorine-containing solute being an ionic salt, (III) at least one additive selected from the group consisting of compounds represented by formulae (1) and (2), and (IV) hydrogen fluoride in an amount of 5 mass ppm or more and less than 200 mass ppm based on the total amount of the components (I), (II), and (III).

  • Publication number: 20200335823
    Abstract: An electrolyte solution for a nonaqueous electrolyte battery according to the present invention includes the following components: (I) a nonaqueous organic solvent; (II) an ionic salt as a solute; (III) at least one kind of additive selected from the group consisting of compounds represented by the general formula (1); and (IV) an additive having a specific structure. Si(R1)a(R2)4-a??(1) The combined use of the components (III) and (IV) provides the effects of reducing the elution of Ni from the Ni-rich positive electrode into the electrolyte solution, without impairing the capacity retention rate of the battery after cycles, and improving the high-temperature storage stability of the electrolyte solution.
