▎ 摘　　要

NOVELTY - Preparing vertically oriented graphite comprises (i) cutting the foam nickel into 1 × 2 cm sheet using hydrochloric acid, deionized water, ethanol for ultrasonic cleaning, and drying; and (ii) preparing mixed solution of graphene oxide dispersion liquid and sodium chloropalladate solution, taking the mixed solution as electrolyte solution, taking the foam nickel sheet after drying as working electrode under the magnetic stirring using cyclic voltammetry to deposit, taking out the foam nickel sheet, cleaning, and drying. USE - The method is useful for preparing vertically oriented graphite, which is useful in electronic devices. The method can be used for preparing graphene/manganese dioxide composite material. ADVANTAGE - The method is simple, easy to control, safe and economical. The vertical orientation graphene has large specific surface area. The composite material obtained by compounding the graphene and manganese dioxide has good electrochemical performance. The method avoids the use of the agglomerant and conductive agent, the needed device is simple and the operation is simple. The cost is low, which is good for mass production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a vertically oriented graphene prepared by the above method; and use method for vertical oriented graphene in preparing vertical oriented graphene/manganese dioxide composite material. DESCRIPTION OF DRAWING(S) - The drawing shows an SEM image of the vertical orientation of the graphite of Example 1.
