▎ 摘  要

A binder-free anode was fabricated from a Co3O4-graphene composite by direct electrospray deposition on current collectors. The highly-interconnected mesoporous structure enables fast ion transport and accommodates the volume expansion of Co3O4 upon Li+ insertion/extraction. The incorporation of highly conductive graphene also improves the charge transport and thus the electrochemical performance.
