Abstract
A non-aqueous electrolyte secondary battery including a positive electrode, a negative electrode and a non-aqueous electrolyte, wherein the non-aqueous electrolyte includes an onium compound, a lithium salt and a chain carbonate having a C═C unsaturated bond. The onium compound is preferably at least one selected from the group consisting of a chain quaternary ammonium compound, a pyrrolidinium compound and a piperidinium compound. The chain carbonate having a C═C unsaturated bond is preferably at least one selected from the group consisting of diallyl carbonate and allyl phenyl carbonate.
Claims7
A non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode and a non-aqueous electrolyte,
- wherein said non-aqueous electrolyte includes an onium compound, a lithium salt and a non-cyclic carbonate having a C═C unsaturated bond,
- wherein said non-cyclic carbonate having a C═C unsaturated bond is at least one selected from the group consisting of diallyl carbonate and allyl phenyl carbonate,
- and wherein the amount of said non-cyclic carbonate having a C═C unsaturated bond is 0.01 to 0.5 mol per 1 mol of said onium compound.
A non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode and a non-aqueous electrolyte,
- wherein said non-aqueous electrolyte includes an onium compound, a lithium salt, a non-cyclic carbonate having a C═C unsaturated bond, and a cyclic carbonate having a C═C unsaturated bond,
- wherein said non-cyclic carbonate having a C═C unsaturated bond is at least one selected from the group consisting of diallyl carbonate and allyl phenyl carbonate, and
- wherein the amount of said non-cyclic carbonate having a C═C unsaturated bond is 0.01 to 0.5 mol per 1 mol of said onium compound.
