Embodiment 1

[0039] A graphene battery negative electrode material, the preparation process of the graphene battery negative electrode material is:

[0040] Step 1: Select copper foil as the base metal, pretreat the base metal of the copper foil, and put the treated base metal foil into the tube furnace;

[0041] Step 2: Turn the No. 2 regulating valve to feed hydrogen, argon or nitrogen protective gas into the tube furnace, heat up to 1000°C through the heating furnace, and stabilize the temperature until the vacuum gauge shows that the interior is vacuum;

[0042] Step 3: Stop feeding the protective gas and switch to methane gas. At high temperature, the C-H bond breaks and various carbon fragments CHx are produced to complete the dehydrogenation process. After the dehydrogenation of the methane molecules, the carbon species on the surface of the base metal gather together, Generate new C-C bonds and clusters, and start to nucleate or form graphene islands. As the number of graphene nucl...

Abstract

The invention discloses a graphene battery negative electrode material and a processing tool thereof. The preparation process of the graphene battery negative electrode material includes the followingsteps that copper foil is selected as base metal, the metal as the base of the copper foil is pretreated, and the pretreated foil with the base metal is placed in a tubular furnace; a secondary adjustment valve is rotated to introduce hydrogen, argon or nitrogen as protective gas into the tubular furnace, the temperature is increased to 1000 DEG C through heating by a heating furnace, the temperature is then stabilized until a vacuum gauge shows that there is a vacuum inside; the introduction of protective gas stops, methane gas is introduced, and at high temperature, a continuous graphene film is formed on the surface of the base metal of the copper foil in the tubular furnace; the graphene battery negative electrode material processing tool can deal with residual methane gas well. The safety is relatively high, the material has a good environmental protection effect, heating and cooling can be integrated, the practicability is high, the cooling efficiency is good, it can be ensuredthat the gas is discharged completely and accidents are avoided effectively.
