摘要： PROBLEM TO BE SOLVED: To provide a lithium secondary battery which has an electrode structural body for a lithium secondary battery, and has a long life and a large capacity.
SOLUTION: As to a current collector, conductive layers 1 are formed on the surface of and inside the current collector, and a porous polymer body 2 is used. The current collector has the preferably percentage of voids of 0.50-0.80, is penetrated 3-dimensionally inside, and deformed without being cut accompanied by the volume change of an anode material accompanied by charge and discharge, and forms the electrode structural body for the lithium secondary battery and the lithium secondary battery to follow expansion and contraction. By this, such problems are solved that the anode material expands and shrinks accompanied by the storage and release of lithium when charging and discharging resulting in a large volume change, and there occurs peeling-off between the anode material and the current collector, and current-collecting performance is lost by this volume change, and further that there is generated a crack in the current collector, and the anode is cut and then the current-collecting performance of the anode is reduced and a cycle life span is reduced.
