Embodiment
[0028] The object of the present invention is to overcome the defects existing in the prior art, and provide a graphene modified energy storage material and a preparation method thereof, which have a simple process and low cost, and can satisfy industrialized production.
[0029] For this reason, technical scheme of the present invention is the preparation method of graphene modified energy storage material, comprises the following steps:
[0030] Step 1: Put the nitride into the tube furnace, evacuate the tube furnace, and then heat the tube furnace under a nitrogen atmosphere. The heating temperature is 720°C, the holding time is 20 hours, and the heating rate is 20°C / min, holding temperature is 720°C, made of Mn 2 N;
[0031] Step 2: According to the chemical formula Mn 3 Each stoichiometric number in CuN is weighed, Mn2N and Cu powder are weighed, and then the two are fully mixed by mechanical ball milling, and the mechanical ball milling time is 20 hours;
[0032] Step...
