Abstract:
An electrode active material layer for a lithium-ion secondary battery is formed from an electrode active material of layered crystal. The electrode active material having layered crystal is oriented in a layer direction of the electrode active material layer, and a plurality of through holes are formed from the surface of the electrode active material layer. The diameter of the through holes is preferably 10 μm to 5000 μm inclusive.
