Abstract
Official abstract text for this publication.
The present invention includes an electrolyte in which an organic acid lithium salt (A) and a boron compound (B) are mixed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithium ion secondary battery comprising an electrolytic solution which is a mixture of an organic acid lithium salt (A), a boron compound (B) and an organic solvent (C), said organic acid lithium salt (A) being lithium oxalate, said boron compound (B) being at least one member selected from the group consisting of boron trifluoride and boron trifluoride complex, wherein the number of moles of lithium atoms in the organic acid lithium salt (A):the number of moles of the boron compound (B) is 100:80 to 100:106 (molar ratio), and wherein a concentration of lithium atoms (Li) in the electrolytic solution is 0.2 to 3.0 mol/kg, in terms of [number of moles (mol) of lithium atoms in the organic acid lithium salt (A)/total mixed amount (kg) of (the organic acid lithium salt (A)+the boron compound (B)+the solvent (C))]. 2. The lithium ion battery according to claim 1 , wherein the organic solvent (C) is one or more kinds selected from the group consisting of a carbonic acid ester compound, a lactone compound, an ether compound, a carboxylic acid ester compound, a nitrile compound, an amide compound, and sulfone compound. 3. The lithium ion battery according to claim 1 , wherein the organic solvent (C) is one or more kinds selected from the group consisting of a carbonic acid ester compound and a lactone compound. 4. The lithium ion battery according to claim 3 , wherein the carbonic acid ester compound is propylene carbonate and the lactone compound is γ-butyrolactone. 5. The lithium ion battery according to claim 1 , which further comprises a matrix polymer (D).
