▎ 摘　　要

NOVELTY - An electrode (200) has conductive layer (103) and active material layer (108) provided on conductive layer. The active material layer includes graphene, active material and hole. The active material has uneven surface. The graphene is provided on to the uneven surface of the active material. The hole included in the active material layer is surrounded with the graphene. USE - Electrode is used for power storage device e.g. lithium-ion secondary battery, lithium-ion capacitor and air cell for electronic appliances (all claimed). ADVANTAGE - The electrode provides power storage device with excellent cycle characteristics and high charge/discharge capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) power storage device; and (2) electronic appliance. DESCRIPTION OF DRAWING(S) - The drawing shows schematic cross-sectional view of electrode. Conductive layer (103) Active material layer (108) Core (109) Outer shell (111) Electrode (200)
