▎ 摘　　要

NOVELTY - Molybdenum disulfide doped epitaxial graphene positive electrode material is prepared by loading 5-20 wt.% epitaxial graphene on 80-95 wt.% molybdenum disulfide nano-flower composite material. USE - Molybdenum disulfide doped epitaxial graphene positive electrode material for magnesium-lithium double salt ion battery. ADVANTAGE - The high conductivity of epitaxial graphene and the high activity and layered structure of molybdenum disulfide in the positive electrode material can effectively promote the efficient saturation insertion/extraction of lithium ion in battery, improve the capacity and rate of the dual salt battery. The molybdenum disulfide doped epitaxial graphene can effectively alleviate the problem of material pulverization caused by lithium ion insertion/extraction causing volume expansion/contraction of the positive electrode material which improve the cycle stability of the magnesium-lithium double salt ion battery, and increase the battery life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for construction of molybdenum disulfide doped epitaxial graphene-magnesium-lithium double salt ion positive electrode material.
