ELECTRODE FOR LITHIUM-ION SECONDARY BATTERY

An object of the present invention is to provide a lithium-ion secondary battery having a large charge and discharge capacity and excellent cycle characteristics irrespective of kind and shape of a current collector. The lithium-ion secondary battery comprises an electrode comprising a primer layer for protecting a current collector and a crosslinking agent layer comprising a compound being capable of crosslinking an aqueous binder contained in the primer layer, the both layers being disposed between a current collector and an active material layer comprising a sulfur-based active material.
