Abstract

The invention relates to a preparation method of graphene-coated porous material, belonging to the technical field of batteries. The method comprises the following steps: (1) uniformly mixing grapheneoxide and AB alloy material for standby; In the AB alloy material, element A is a metal element with high melting point and high boiling point, element B is a metal element with lower boiling point and lower melting point relative to element A; (2) heating and holding the graphene oxide and the AB alloy material in the step (1) under the vacuum condition, removing the B element gradually, and reducing the graphene oxide in situ to obtain the graphene-coated porous alloy composite electrode material. The invention uniformly coats graphene oxide on the surface of porous metal through vacuum in-situ reduction, realizes the synchronization of graphene coating and porous metal preparation, and can prepare porous alloy composite electrode material coated by graphene in one step. The process issimple and practical, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method for preparing a graphene-coated porous material. Background technique [0002] Porous material, that is, a large number of directional or random pores are dispersed in the material, and the diameter of these pores is generally 2μm-3mm. Due to the different design requirements for the holes and the influence on the performance of the material, the holes can be foam type, lotus type or honeycomb type, etc. Porous materials can also be divided into two categories according to their pore shape: independent pore type and continuous pore type. Among them, the independent type porous material has the characteristics of small specific gravity, high rigidity, high specific strength, good vibration absorption and sound absorption performance; the continuous type porous gold material not only has the above characteristics, but also has the characteristics of good permeability an...
