Zusammenfassung: | The invention belongs to the technique of energy storage batteries, and particularly relates to a graphene derived material with a partial area being graphited and for an aluminum ion battery. The material is formed by three-dimensional lapping of 3-10 layers of graphene layers, the graphited degree of the graphene layers is 10-99%, the transverse size of the graphene layers is 10-100 microns, andthe material is obtained by adopting a high temperature treatment method or a chemical treatment method. Compared with the prior art, the material has the beneficial effects that (1) the invention provides a graphene derived material with the partial area being graphited, precise control of the graphited degree of the graphene material can be achieved by changing the thermal treatment temperature(or categories of reducing agents and amount of the reducing agents) and the treatment time; and (2) the storage effect of the graphene derived material with the partial area being graphited on electrochemical active substanc |
