Document Type and Number:
Japanese Patent JP5214088
Kind Code:
B2
Abstract:
To provide a nonaqueous electrolyte battery capable of increasing volume energy density by sufficiently filling a nonaqueous electrolyte in voids in a mix even in a positive electrode or a negative electrode having high filling density.
The nonaqueous electrolyte contains inorganic anions and organic anions, the inorganic anion contains either one or both of PF6-and BF4-, and the organic anion contains one or more kinds represented by (CnF2n+1SO2)(CmF2m+1SO2)N-(n and m are an integer of 1-4; n and m may be the same or different.). The impregnation of the nonaqueous electrolyte to a high density electrode to which the impregnation of the electrolyte was difficult is made easy. This is applied even to the nonaqueous electrolyte containing 60 vol.% or more high dielectric constant solvent having a dielectric constant of 40 or more.
