▎ 摘　　要

NOVELTY - Preparation of graphene hydrogen-rich ceramic ball involves grinding an electrode material, graphene and alcohol in a pressure tank to form a slurry, spraying and granulating the slurry to form micro-battery material, adding an electrolyte to the micro-battery material, stirring in a mixer, adding deionized water, molding, drying the molded product at low temperature, sintering, cooling to room temperature, applying a nano-silicon powder, and sintering. USE - Preparation of graphene hydrogen-rich ceramic ball for preparing hydrogen-rich water (all claimed) for hot water and tea. ADVANTAGE - The method produces ceramic ball which is capable of producing hydrogen-rich water which is weakly alkaline water having hydrogen content of up to 1300 ppb and reduced oxidation-reduction potential value to produce negative potential water. Hydrogen-rich water is healthy and safe to drink. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the graphene hydrogen-rich ceramic ball for preparing hydrogen-rich water.
