 Between our obsession with mobile electronics and the grand popularity of electrical vehicles, lithium-iron batteries is growing at an astonishing rate. Most of that demand is being driven by automotive cells, which consume 60% of lithium-iron batteries. It's not hard to imagine how far that's going to go in time, which raises the biggest question. What happens to those batteries when they die? As we can see, it brings a severe damage due to its unmanaged recycled treatment, which causes environmental pollution and unhealthy effects to people. So, look at these two pictures of children in different destinies. Some enjoy the use of graphite in batteries, some suffer from the pollution of it. Unlike castle metal reducing circumstances, which has achieved high efficiency of regeneration into battery-grade noble metal, graphite, the highest proportion of single components in battery, has been ignored. In a traditional processing method, the waste graphite has been inherited directly into ash and emits a large amount of carbon dioxide, which is 1,331,600 tons of carbon dioxide in 2030 as forecasting. It goes to the Mount of South Africa's gas emission, or Japan's coal emission. The amount is so large that it would take 2,000 so many long rainforests to absorb it, causing the effects of greenhouse gases. For comparison with traditional measurement, the industry is now in high demand of a green-low-carbon method. We have found a sustainable greenway, the mechanical chemical method to realize the transformation from spent graphite into graphenec nanomaterials, which had excellent properties in several domains, like semiconductor activity, electrical conductivity, compression resistance, and so on. Thus, the application scenarios can be widened into multiple domains, other regeneration into energy storage systems, used in solar cells, cooling materials, pressure sensors, and so on. The main technique of our project, ball mining, can effectively make graphite into senior materials through its sharing and impacting force. With specific steel ball and different kinds of addition agents, we can produce various type of graphene-like nanomaterials under diverse machine parameters. Characterization of atomic force macroscope, our product has a height of 2.8 nanometers, and graphite with fewer than five layers has appeared. This way we can produce materials with strong application properties in environmental friendly way. In terms of material application, the heat dissipation capacity, electrochemical application, absorbent utilization, compared with the same carbon-based materials, our product shows an excellent practice. Our recycled product carry higher practice in key industrial application than even new materials. Here the carbon footprint performance, our method highly reduces the use of materials and energy consumption, also enhances the performance of recycled materials and improves the utilization rates of resources. Such a reduction in carbon emission can have a huge economic effect in carbon market. This will make waste of graphite recycling no longer a burden on the environment and business, but a win-win for them both. To sum up, we've changed the industry chain which directly leads to the emission of carbon dioxide into a circle one using our easy environmental friendly mechanical method to get a low cost, high profit, high quality product and reuse it in various application. Our method gives these spent graphite a signal life and effectively reduces the carbon dioxide emission, protecting both human and nature's health. Guided by policies such as European Battery Recycling Regulation and carbon neutrality, we aim to achieve materials recycling and generate substantial returns. Additionally, we hope to contribute to tackling the upcoming wave of retirement in the bathrooms by investing in and establishing startups that liberate our advanced technology. We can effectively solve the current pollution challenge of battery recycling.
