Document Type and Number:
Japanese Patent JP5942849
Kind Code:
B2
Abstract:
To provide a non-aqueous electrolyte solution for secondary batteries, which has a long term flame retardancy and which is excellent in cycle properties particularly under high voltage conditions and in high rate charge/discharge properties, and a secondary battery using such a non-aqueous electrolyte solution for secondary batteries. A non-aqueous electrolyte solution for secondary batteries, comprising a lithium salt and a solvent for dissolving the electrolyte salt, which comprises a specific hydrofluoroether, a specific ether compound and a specific carbonate compound, wherein the ratio (N o /N Li ) of the total number of moles (No) of etheric oxygen atoms derived from the above ether compound to the total number of moles (N Li ) of lithium atoms derived from the lithium salt, contained in the solvent for dissolving the electrolyte salt, is more than 1 and at most 6; and a secondary battery using such a non-aqueous electrolyte solution for secondary batteries.
