▎ 摘　　要

NOVELTY - Preparing network-shaped graphene nano material involves calcining the carbon source organic material at 500-1000 degrees C to obtain calcined material, adding water for washing, filtering to obtain filter residue, and annealing processing under the protective atmosphere at 200-1600 degrees C. USE - Method for preparing network-shaped graphene nano material used as sodium/potassium ion battery electrode material (claimed). ADVANTAGE - The method enables to prepare network-shaped graphene nano material which has no additional template process, simple technical flow, low requirement of device, wide interlayer spacing and excellent conductivity, and excellent storage property. It is easy to realize industrial production.
