▎ 摘　　要

NOVELTY - High-stability composite lithium cathode comprises a copper foil substrate with an appropriate thickness, where graphene interconnected array structure with a micropore structure that is physically connected to the copper foil substrate and vertically grown, and metal lithium filled in the micropores. USE - The high-stability composite lithium cathode is useful in electronic and electric equipment. ADVANTAGE - The high-stability composite lithium cathode reduces deposition over-potential of lithium atoms, reduces local current density in the charging and discharging process, induces uniform deposition of lithium ions, inhibits growth of lithium dendrite, provides stable deposition space for the metal lithium on the cathode, eliminates volume change of the battery in the charging and discharging process, greatly improves cycle stability of the lithium-ion battery, has large specific surface area, and reduces interface impedance of the composite lithium anode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of high-stability composite lithium cathode.
