  • Electrolyte medium for lithium secondary battery and lithium secondary battery
    Patent number: 11876184
    Abstract: To provide a lithium secondary battery capable of suppressing short circuits and having high energy density and high output. An electrolyte medium for a lithium secondary battery includes a low dielectric constant solvent, a lithium salt, and a polyvalent cation salt. The polyvalent cation salt is dispersed as particles in the electrolyte medium and can flow without being immobilized. The electrolyte medium includes 20 mass % or less of a high dielectric constant solvent. A lithium secondary battery including the electrolyte medium for a lithium secondary battery can suppress short circuits and provide high energy density and high output.

  • ELECTROLYTE AND MAGNESIUM SECONDARY BATTERY
    Publication number: 20170018804
    Abstract: To provide an electrolyte and a magnesium secondary battery that can embody a magnesium secondary battery having room-temperature operability and satisfactory cyclability. An electrolyte 13 including an organic solvent, magnesium salt and cyclic acid anhydride is provided. Cyclic acid anhydride is preferably contained at a concentration at least equimolar to magnesium salt, and is further preferably contained at a molar concentration 1.0 to 3.0 times that of magnesium salt. Further, a magnesium secondary battery 1 including these electrolyte 13 and a negative electrode 12 containing magnesium or magnesium alloy is provided.
