Lecture Profile

The development of efficient and low-cost energy storage techniques is crucial to promoting the diversified and efficient use of renewable energy sources. Lithium-ion batteries take a dominating position in the power battery and electrochemical large-scale energy storage markets, with rapidly expanding applications. However, lithium-ion batteries rely on scarce resources such as lithium, cobalt and nickel that are unevenly distributed and in oligopolistic markets. Although China is rich in lithium resources, it is not well endowed, and is lacking in cobalt and nickel resources, and is even highly dependent on the import of multiple resources, including lithium, cobalt, nickel. Therefore, it is imperative to develop efficient recycling techniques for key resources of lithium-ion battery materials. Our team has been devoted to the research and development of new techniques for the clean recycling of lithium-ion battery materials and the reusing of recycled products in recent years, proposed a series of new methods such as direct repair of failed cathode materials with recyclable deep eutectic solvents, backed by the repair mechanism revealed, and established the synergetic recycling technique for battery cathodes & anodes targeting closed-loop recycling and high-value utilization of cathode & anode materials.
