▎ 摘　　要

NOVELTY - 1,5-Dihydroxyanthraquinone copper coordination polymer (I) is new. USE - 1,5-Dihydroxyanthraquinone copper coordination polymer for 1,5-dihydroxyanthraquinone copper coordination polymer/graphene composite used as cathode material for lithium ion batteries (claimed). ADVANTAGE - The 1,5-dihydroxyanthraquinone copper coordination polymer is more convenient for the migration of lithium ions and electrons, and effectively improves the conductivity and electrochemical performance of the electrode material. DETAILED DESCRIPTION - 1,5-Dihydroxyanthraquinone copper coordination polymer of formula (I) is new. n=undefined. An INDEPENDENT CLAIM is included for a method for preparing 1,5-dihydroxyanthraquinone copper coordination polymer of formula (I).
