The invention provides a method for fabricating a battery electrode plate and a battery by employing a recycled material. The method is used for solving the technical problems that an electrode material in the prior art is high in cost or a manufacturing process is complicated, lithium ion dispersion effect is relatively poor, polystyrene plastic is difficult to degrade and an environment is easily polluted. The method for fabricating the battery electrode plate by employing the recycled material comprises the steps of material preparation, size mixing, plate brushing and plate production. Themethod for fabricating the battery by employing the recycled material comprises the steps of cutting, electrolyte preparation, negative electrode assembly, positive electrode assembly and sealing. Through implementing the method provided by the technical scheme, the polystyrene plastic is cracked at a high temperature to produce a graphitized carbon material, the harm of waster polystyrene plastic to the environment is reduced, a stable lithium ion battery negative electrode material with excellent battery performance is provided, the process flow is simple, and mass industrial production isfavorably achieved.
Description
technical field [0001] The invention relates to the field of electrode materials, in particular to a method for preparing battery electrode sheets and batteries using recycled materials. Background technique [0002] The most important part of the electrode lithium-ion battery, and the production of lithium-ion battery electrodes is the most important step in the production of lithium-ion batteries. In the prior art, graphite-based carbon materials, Si-based, Sn and other alloys are mainly used as negative electrode materials for batteries. These materials are either expensive, or have complex manufacturing processes and poor lithium ion dispersion effect. [0003] Polystyrene plastic is widely used in product packaging in various industries. It can only be landfilled and will not degrade for decades. After polystyrene plastic degrades, it will still pollute water and soil. [0004] We therefore propose a method for the production of high-quality anode materials for lithiu...
