▎ 摘　　要

NOVELTY - Preparing basic iron oxide/graphene cathode material comprises (i) providing graphene ethanol solution, (ii) adding ferric chloride hexahydrate into graphene ethanol solution and stirring to dissolve, (iii) adding ammonium bicarbonate and stirring to dissolve, (iv) stirring and reacting at room temperature, then de-ionized washing the material obtained by the reaction, centrifuging and drying to obtain final product. USE - The basic iron oxide\graphene cathode material is useful in preparing lithium ion battery cathode material (claimed). ADVANTAGE - The method has low cost, mild reaction conditions and short reaction time; utilizes cheap and easily available raw materials; and is environmentally friendly; produces cathode material which has a capacity of 600mAh.g-1 at a charge and discharge current of 100mA.g-1, high reversible capacity, excellent cycle stability and excellent electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for basic iron oxide\graphene cathode material obtained by above method.
