▎ 摘　　要

NOVELTY - Patterned vertical graphene, is claimed. The purity of the vertical graphene is 99%, the geometric size is 1-20 microns, and the number of layers are 1-10 layers. USE - Patterned vertical graphene used in energy storage, sensor, and field emission material, super capacitor, lithium-ion battery, solar battery, vacuum electronic device, and electromagnetic shielding field. ADVANTAGE - The method has simple process, convenient operation, low production cost and characteristics. The patterned vertical graphene has good conductivity, large specific surface area, strong electrochemical stability and can be widely applied to super capacitor, lithium-ion battery, solar battery and other energy device. The method sets the mask on the substrate to control the growth area of the vertical graphite can effectively adjust the distance between the vertical graphene film, reduce the field shielding effect, improve the electron emission performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of patterned vertical graphite.
