Title:
NONAQUEOUS ELECTROLYTE AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2019197633
Kind Code:
A
Abstract:
To provide nonaqueous electrolyte and a nonaqueous secondary battery which restrains elution of positive electrode transition metal, and is capable of exhibiting excellent load characteristics even after high-temperature storage, when used in a battery, in nonaqueous electrolyte containing acetonitrile excellent in balance of viscosity and relative dielectric constant, and fluorine-containing inorganic lithium salt.SOLUTION: Nonaqueous electrolyte contains a nonaqueous solvent containing acetonitrile, a fluorine-containing inorganic lithium salt, and a nitrogen-containing six-six-membered condensation bicyclic compound. Preferably, the nitrogen-containing six-six-membered condensation bicyclic compound is a compound having quinoline skeleton, isoquinoline skeleton, or naphthyridine skeleton.SELECTED DRAWING: None
