▎ 摘　　要

NOVELTY - A composite electrode material is produced by plasma discharge method by doping non-metal elements on transition metal selenides and ordered porous graphene aerogels, where non-metal element is one or more of nitrogen, boron, phosphorus and sulfur and transition metal selenide is nickel selenide, cobalt selenide or nickel-cobalt double metal selenide. USE - Composite electrode material for supercapacitors and batteries. ADVANTAGE - The composite electrode material has porous network structure, mass capacity of up to 1902 F/g, and excellent rate performance and cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite electrode material.
