Our total solution service provides technical guidance on the planning process for establishing a new battery recycling factory. Our electronic-grade recycled materials from wasted lithium ion batteries including lithium carbonate, lithium hydroxide, and nickel sulfate have a purity of more than 99.95%. These cathode materials can be used to be remanufactured in new lithium-ion batteries with higher performance. 1. Our recycled lithium carbonate lattice structure is not significantly different from high-purity lithium carbonate commercially available in Japan. Both of the lattice structures are octahedral. 2. The electrical performance of our recycled lithium carbonate is similar to high-purity lithium carbonate commercially available in Japan. Both average capacitances are more than 125 mAh/g. 3. The average coulombic efficiency and capacity retention are close to 99% and the average capacitance is 0.2% higher than lithium carbonate commercially available in Japan. 1. Currently, most methods for recycling waste lithium batteries involve discharging them in highly concentrated brine, followed by crushing. However, there is often a risk of explosion during lithium battery crushing due to the residual charge. Using concentrated brine for discharge would corrode the battery and resulting in the generation of heavy metal sludge. Our chemicals, "UW- Discharging Agent" can discharge different types of lithium batteries, such as LFP, LCO, NCM, and NCA batteries. After discharging, the residual voltage can be deducted below 1 V within 2 hours, making it safe for crushing. 2. Traditional hydrometallurgy extracts the unwanted elements, reducing the saturation concentration of cobalt (Co) and longer reaction time. In contrast, utilizing our patented "UW530" allows us to extract selective elements from the solution, thereby increasing extraction concentration and reducing reaction time. Our most effective environmentally friendly "UWin discharging agent" enables the proper discharge and safety storage of lithium-ion batteries in communities, businesses, and recycling plants, thereby mitigating the potential risk of fire. Our hydrometallurgy process fits this framework by recovering valuable materials such as lithium, cobalt, nickel, and other metals from end-of-life lithium-ion batteries, thus reducing the need for mining and minimizing environmental impact. Recycling end-of-life lithium-ion batteries can reduce reliance on worldwide lithium mining. Additionally, it would guarantee a local supply chain of reclaimed materials. The University of Technology Sydney (UTS) estimates that by 2030, there will be 30,000 tons of wasted lithium ion batteries in Australia. Academic and private environmental organization has been concerned about the disposal of LIB in the landfill. This will lead to the risk of combustion, and environmental and water pollution from hazardous chemicals, posing health issues. Furthermore, eight of the largest lithium-producing countries source lithium from lithium salt mines, where the extraction process requires large amounts of water, leading to pollution and land alkalization. According to EU New Battery Regulation published in July 2023, various measures are outlined to enhance the management of batteries. Among the most crucial highlights is the establishment of minimum levels of recycled content for specific elements in batteries. By 2031: 16% cobalt, 6% lithium, and 6% nickel used in batteries are required to derive from recycled sources. In addition, every battery in the EU must specify the amount of recycled content it contains. Shortly, there will be a significant demand for recycled materials for lithium-ion batteries. However, in current situations in Taiwan and the globe, there is still a lack of reliable lithium-ion battery recycling mechanisms.
