▎ 摘　　要

NOVELTY - Producing graphene-enabled hybrid particulates involves preparing a mixture suspension of graphene sheets and a selenium material dispersed in a liquid medium and dispensing and forming mixture suspension into hybrid particulates, where at least one of the hybrid particulates comprises a single or multiple graphene sheets and multiple fine selenium particles or coatings, having a diameter or thickness of 0.5-10 mu m, and the graphene sheets and the selenium particles or coatings are mutually bonded or agglomerated into hybrid particulate containing an exterior graphene sheet or multiple exterior graphene sheets embracing the selenium particles or coatings, and where graphene is in an amount of 0.01-30 wt.% based on the total weight of graphene and selenium combined. USE - Method for producing graphene-enabled hybrid particulates for use as a cathode active material of an alkali metal battery. ADVANTAGE - The method enables to produce graphene-enabled hybrid particulates which increases the energy density of lithium ion batteries, high capacities over a large number of cycles, specific energy greater than 300 Watt-hour/kg, preferably greater than 350 Watt-hour/kg, and more preferably greater than 400 Watt-hour/kg. The method is simple, cost-effective, and easy-to-implement approach to preventing potential lithium metal dendrite-induced internal short circuit and thermal runaway problems in lithium metal-selenide batteries.
