ABSTRACT:
An anode for lithium-ion secondary battery is provided as one capable of ensuring sufficient safety (suppression of dendrites) while achieving a higher capacity (higher density of the electrode), and permitting formation of a lithium-ion secondary battery with excellent high-rate discharge performance. An anode for lithium-ion secondary battery has a current collector, and an active material-containing layer formed on the current collector, the active material-containing layer is comprised of an outermost layer disposed on the farthest side from the current collector, and a lower layer composed of at least one layer disposed between the outermost layer and the current collector, and a degree of flexion of the outermost layer is smaller than that of the lower layer.
