Abstract
Official abstract text for this publication.
A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode and an electrolyte solution, wherein the negative electrode includes a negative active material layer, the electrolyte solution contains fluoroethylene carbonate, and when a content (mg) of the fluoroethylene carbonate is denoted as X and a reaction area (m 2 ) of the negative active material layer is denoted as Y, X and Y satisfy a relation of 10≦(X/Y)≦100.
First claim
Opening claim text (preview).
What is claimed is: 1 . A nonaqueous electrolyte secondary battery comprising: a positive electrode; a negative electrode; and an electrolyte solution, wherein the negative electrode includes a negative active material layer, the electrolyte solution contains fluoroethylene carbonate, and when a content (mg) of the fluoroethylene carbonate is denoted as X and a reaction area (m 2 ) of the negative active material layer is denoted as Y, X and Y satisfy a relation of: 10≦( X/Y )≦100. 2 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein when the content (mg) of the fluoroethylene carbonate is denoted as X and the reaction area (m 2 ) of the negative active material layer is denoted as Y, X and Y satisfy a relation of: 10≦( X/Y )≦50. 3 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein when the content (mg) of the fluoroethylene carbonate is denoted as X and the reaction area (m 2 ) of the negative active material layer is denoted as Y, X and Y satisfy a relation of: 10≦( X/Y )≦40. 4 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein the content of the fluoroethylene carbonate in the electrolyte solution is 12.2% by weight or less. 5 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein the electrolyte solution contains a solvent having a reduction potential lower than a reduction potential of the fluoroethylene carbonate. 6 . The nonaqueous electrolyte secondary battery according to claim 5 , wherein the solvent having a reduction potential lower than the reduction potential of the fluoroethylene carbonate is ethyl methyl carbonate. 7 . The nonaqueous electrolyte secondary battery according to claim 6 , wherein a weight ratio of the fluoroethylene carbonate to the ethyl methyl carbonate is 0.5 or less. 8 . The nonaqueous electrolyte secondary battery according to claim 6 , wherein a weight ratio of the fluoroethylene carbonate to the ethyl methyl carbonate is 0.2 or less. 9 . A nonaqueous electrolyte secondary battery comprising: a positive electrode; a negative electrode; and an electrolyte solution, wherein the negative electrode includes a negative active material layer, the electrolyte solution contains fluoroethylene carbonate, and when a content (mg) of the fluoroethylene carbonate is denoted as X and a reaction area (m 2 ) of the negative active material layer is denoted as Y, the electrolyte solution is prepared so as to satisfy a relation of: 10≦( X/Y )≦100 in preparing the nonaqueous electrolyte secondary battery.
