中国科大低成本化解全固态锂电池界面问题

Core Viewpoint - A new low-cost solution for solid-state lithium batteries has been proposed by Professor Ma Cheng from the University of Science and Technology of China, addressing the challenge of maintaining good interface contact under low external pressure, which is crucial for practical applications [1]. Group 1: Industry Insights - Solid-state lithium batteries have the potential to overcome the limitations of current liquid lithium-ion batteries, which struggle to balance high safety and high energy density [1]. - The challenge with solid-state batteries lies in the need for solid electrolytes and electrodes to maintain contact under high external pressures, often requiring tens to hundreds of megapascals, which is impractical in real-world scenarios [1]. Group 2: Research Developments - The key to solving the interface contact issue is to develop a solid electrolyte that can effectively change shape and maintain tight contact with the electrode materials, even under low pressure [1]. - The newly developed solid electrolyte, lithium zirconium aluminum chloride oxide, demonstrates the desired performance for commercial viability [1].
