Abstract:
The present invention has an object of providing a lithium secondary battery and an electrode for a lithium secondary battery having a superb cycle characteristic.The present invention relates to an electrode for a lithium secondary battery, and a lithium secondary battery including the electrode, the electrode including a current collector and an active substance structure provided on the current collector, wherein the active substance structure includes at least one first layer containing a first material for occluding and releasing lithium ions and at least one second layer containing a conductive second material which does not chemically react with lithium; the first layer and the second layer are alternately laminated; and the second layer has a Young's modulus larger than the Young's modulus of the first layer.
