Latest Patents

One of Zheng Li's latest patents focuses on "Methods and systems for scalable direct recycling of battery waste." This invention outlines a comprehensive approach to recycling battery waste, which includes applying a first heat treatment at temperatures ranging from about 100° C. to about 700° C. This initial treatment effectively decomposes at least 80 wt % of the binder, allowing for the separation of electrode material from the current collector. Following this, a second heat treatment is applied at temperatures between about 400° C. and about 1,200° C. to regenerate the electrode material, ensuring that at least 90 wt % of the remaining binder is decomposed. Additionally, the method may involve surface treatments to eliminate coatings and impurities from the electrode material, enhancing the overall recycling process.
