▎ 摘  要

NOVELTY - Electrode comprises: an object comprising silicon and an oxide; and a film-like carbon-based material on the object, where the film-like carbon-based material includes many sheets of graphene. USE - The electrode is useful for secondary battery including graphene-coated object. ADVANTAGE - The electrode: has advantage of unlikely to break in addition to a certain degree of strength; of secondary battery is advantageous in occlusion and release of lithium ions as compared to the case of using a spherical carbon-based material and occluded more efficiently as compared to the case of using a spherical active material; and improves secondary battery can be thinner and more lightweight; and improves lithium occlusion efficiency of a secondary battery. DESCRIPTION OF DRAWING(S) - The figure shows cross-sectional view of the electrode. Solution (100) Object (101) Graphene oxide (102) Another graphene oxide (103)
