▎ 摘　　要

NOVELTY - Lithium secondary battery comprises negative electrode current collector (10); negative electrode layer (20) disposed on negative electrode current collector; intermediate layer (30) disposed on negative electrode layer and comprising a solid electrolyte or a separator; a positive electrode layer (40) disposed on the intermediate layer; positive electrode current collector disposed on the positive electrode layer; and reinforcing layer disposed on an outside of the negative electrode current collector and the positive electrode current collector and comprising a matrix comprising a polymer and a thermally conductive filler dispersed in the matrix (61). USE - Lithium secondary battery used in motor vehicles such as passenger automobiles includes sports utility vehicles (SUV), buses, trucks, various commercial vehicles, watercraft including a variety of boats and ships, aircraft, and the like, and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (e.g. fuels derived from resources other than petroleum). As referred to herein, a hybrid vehicle is a vehicle has power, for example both gasoline-powered and electric-powered vehicles. ADVANTAGE - The lithium secondary battery may be effectively prevented from being broken by volume expansion of the electrode, and it is possible to obtain a lithium secondary battery having excellent cell performance and cycle life characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a lithium secondary battery. DESCRIPTION OF DRAWING(S) - The diagram shows an exemplary lithium secondary battery. 10Negative electrode current collector 20Negative electrode layer 30Intermediate layer 40Positive electrode layer 61Matrix
