Abstract
Official abstract text for this publication.
A nonaqueous electrolyte secondary battery includes a positive electrode that includes a positive electrode current collector, an intermediate layer on the positive electrode current collector, and a positive electrode mix layer on the intermediate layer. The intermediate layer contains a flame retardant and a conductive material having a heat conductivity of 10 W/m·K or more.
First claim
Opening claim text (preview).
What is claimed is: 1 . A nonaqueous electrolyte secondary battery comprising: a positive electrode; a negative electrode; and a nonaqueous electrolyte, wherein the positive electrode includes a positive electrode current collector, an intermediate layer on the positive electrode current collector, the intermediate layer containing a flame retardant and a conductive material having a heat conductivity of 10 W/m·K or more, and a positive electrode mix layer on the intermediate layer. 2 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein the highly heat conductive material is at least one selected from diamond, graphite, aluminum nitride, silicon carbide, aluminum oxide, and tungsten oxide. 3 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein the flame retardant is at least one selected from an aromatic phosphate ester and a melamine-acid salt. 4 . The nonaqueous electrolyte secondary battery according to claim 1 , wherein the flame retardant is contained in a ratio of 0.5% to 3% by weight relative to a weight of a positive electrode active material per unit area.
