Problems solved by technology
[0002] At present, electric vehicles such as electric motorcycles and electric vehicles mainly use lead-acid batteries and lithium batteries. These types of batteries have slow charging speed, poor deep discharge performance, and short cycle life, especially lithium batteries. Poor safety, The cost of batteries is too high, but the recovery rate is not high. Therefore, it can be seen from actual use that these fatal shortcomings of the above-mentioned batteries have become the biggest bottleneck in the development of pure electric vehicles.

Embodiment Construction
[0018] like figure 1 , the preparation process of the electrode plate material of the graphene nickel-zinc battery of the present invention comprises the following steps:
[0019] 1) mixing the electrode plate active material with graphene, then adding the obtained mixed material into distilled water to dilute and stir evenly;
[0020] 2) Put the diluted mixed material into the preparation bin of the ball mill;
[0021] 3) Under the conditions of evacuating the preparation chamber and maintaining a constant temperature, the variable-speed ball milling treatment is carried out several times in a cycle, wherein: increasing the rotating speed step by step and then reducing the rotating speed step by step is one cycle (that is, increasing the rotating speed step by step and then reducing the rotating speed step by step is one cycle) variable speed ball milling process), the number of speed changes in the step-by-step speed-up process is the same or different from the speed change...

The invention discloses a preparation process of an electrode plate material of a graphene nickel-zinc battery and the graphene nickel-zinc battery. The preparation process includes: mixing an active electrode plate material with graphene, adding into distilled water for dilution, and evenly stirring; placing the diluted mixed material into the preparing bin of a ball milling machine; vacuumizing the preparing bin, and performing serval times of variable-speed ball milling in a circulating manner under constant temperature; dewatering and drying products obtained by the variable-speed ball milling to obtain the composite electrode plate material with the active material being evenly and sufficiently wrapped by graphene. The graphene nickel-zinc battery with the electrode plate material prepared by the preparation process is fast in charging, high in discharge rate, good in deep discharge, long in circulating service life, low in cost, capable of satisfying the application requirements of pure electric vehicles, and the like.
Description
technical field [0001] The invention relates to a method for preparing a positive / negative electrode plate material of a graphene nickel-zinc battery and a graphene nickel-zinc battery realized by the positive and negative electrode plate materials prepared based on the method, belonging to the technical field of battery preparation. Background technique [0002] At present, electric vehicles such as electric motorcycles and electric vehicles mainly use lead-acid batteries and lithium batteries. These types of batteries have slow charging speed, poor deep discharge performance, and short cycle life, especially lithium batteries. Poor safety, The cost of batteries is too high, but the recovery rate is not high. Therefore, it can be seen from actual use that these fatal shortcomings of the above-mentioned batteries have become the biggest bottleneck in the development of pure electric vehicles. [0003] Judging from the current use requirements, pure electric vehicles have hig...
