▎ 摘　　要

NOVELTY - An anode comprises multiple porous graphene balls and multiple particles or coating of a lithium-attracting metal or sodium-attracting metal at a graphene ball-to-metal volume ratio of (2/98)-(98/2), where the porous graphene ball comprises graphene sheets formed into said ball having a diameter of 100 nm-20 microm and a pore or multiple pores having a pore volume fraction of 10-99.9% based on the total graphene ball volume, and wherein said lithium-attracting metal or sodium-attracting metal, having a diameter or thickness of 1 nm-20 microm, is chosen from gold, silver, magnesium, zinc, titanium, potassium, aluminum, iron, manganese, cobalt, nickel, tin, vanadium, and chromium or its alloy and is arranged outside the graphene balls or on exterior surfaces of the graphene balls. USE - Anode used for alkali metal battery such as lithium metal battery, lithium-sulfur battery, lithium-selenium battery, lithium-air battery, sodium metal battery, sodium-sulfur battery, sodium-selenium battery, and sodium-air battery (all claimed). Uses include but are not limited to electric vehicle, hybrid electric vehicle, laptop computers and mobile phones. ADVANTAGE - The anode has reduced electrode exchange current density, and provides battery with excellent charge/discharge characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) An alkali metal battery, which comprises a cathode, the anode, a lithium source or a sodium source in ionic contact with the anode, and an electrolyte in ionic contact with both the electrodes, (2) A lithium-ion battery, which comprises the anode, a cathode, an electrolyte in ionic contact with the electrodes, where the cathode comprises a lithium-containing cathode active material that releases lithium ions into the electrolyte when the battery is charged and the released lithium ions move to the anode and react with the metal or form an alloy with the metal in the anode, where the anode is lithium-free, (3) A sodium-ion battery, which comprises the anode, a cathode, an electrolyte in ionic contact with the electrodes, where the cathode comprises a sodium-containing cathode active material that releases sodium ions into the electrolyte when the battery is charged and the released sodium ions move to the anode and react with the metal or form an alloy with the metal in the anode, and (4) Production of the anode, which involves providing a slurry comprising a mixture of multiple graphene balls and a lithium-attracting metal or sodium-attracting metal, and a binder or adhesive dispersed/dissolved in a liquid medium, where the lithium-attracting or sodium-attracting metal is chosen from gold, silver, magnesium, zinc, titanium, potassium, aluminum, iron, manganese, cobalt, nickel, tin, vanadium, and chromium or its alloy, and dispensing and depositing the slurry onto a surface of a current collector and removing the liquid medium to form the anode.
