<P>PROBLEM TO BE SOLVED: To provide a lithium secondary battery excellent in the high-rate characteristic and the cycle characteristic, and to provide a method of manufacturing the same. <P>SOLUTION: This lithium secondary battery 100 includes: a positive electrode having a positive electrode collector 32 and a positive electrode active material layer 34 formed on the surface of the collector and including positive electrode active materials; and a negative electrode having a negative electrode collector 42 and a negative electrode active material layer 44 formed on the surface of the collector and including negative electrode active materials. At least one active material layer of the positive electrode active material layer and the negative electrode active material layer includes at least one kind of binding material, and is characterized by forming so that degree of crystallization of the binding material becomes higher as it comes closer to the surface of the collector. <P>COPYRIGHT: (C)2011,JPO&INPIT |
