▎ 摘　　要

NOVELTY - Anode comprises multiple porous graphene composite balls. The porous graphene composite ball comprises multiple of graphene sheets and ion-conducting material at graphene-to-ion-conducting material weight ratio from 2/98-98/2 that are combined to form into composite ball has diameter from 50 nanometer-20 micrometer and pore or multiple pores has pore volume fraction from 10-99.9% based on the total porous graphene composite ball volume. USE - Anode for lithium battery or sodium battery. ADVANTAGE - The anode has good working conductivities. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a alkali metal battery, which comprises cathode, anode, optional lithium source or optional sodium source in ionic contact with anode, electrolyte in ionic contact with both cathode and anode;#a lithium-ion battery, which comprises anode, cathode, electrolyte in ionic contact with anode and cathode, cathode comprises lithium-containing cathode active material that releases lithium ions into electrolyte when the battery is charging and released lithium ions moving to the anode; and#a sodium-ion battery, which comprises anode, cathode, electrolyte in ionic contacting with anode and cathode, cathode comprises sodium-containing cathode active material that releasing sodium ions into electrolyte when battery is charging and released sodium ions moving to the anode; and#a method for producing anode, which involves providing and dispersing multiple porous graphene composite balls and optional binder or adhesive in liquid medium to form slurry and dispensing and depositing slurry onto surface of current collector and removing liquid medium to form the anode.
