A research team led by Professor Dennis Y. C. Leung of the University of Hong Kong (HKU)'s Department of Mechanical Engineering has achieved a major breakthrough in battery technology with the development of a high-performance quasi-solid-state magnesium-ion (Mg-ion) battery. This innovative design offers a sustainable, safe, and high-energy-density alternative to conventional lithium-ion batteries, addressing the limitations of material scarcity and safety concerns. Recently published in Science Advances under the title "Next-generation magnesium-ion batteries: The quasi-solid-state approach to multivalent metal ion storage," the new Mg-ion battery has the potential to revolutionize the industry. "It is a game-changing development," said Professor Leung....
