Foreign Media: Chinese Team Develops Flexible Organic Lithium Battery, Promising to Revolutionize Wearable Devices
Chinese scientists have developed a flexible and safe organic lithium-ion battery, which is expected to be applied in wearable electronic devices and extreme environments. The core breakthrough of this achievement lies in a new type of organic cathode material that maintains efficient and stable performance over a wide temperature range from minus extremely low temperatures to 80 degrees Celsius. The related research was led by research teams from Tianjin University and South China University of Technology, and the paper was published in the journal "Nature" on February 18.
Traditional lithium-ion batteries use inorganic minerals such as lithium cobalt oxide and lithium iron phosphate as cathode materials, with production costs constrained by mineral resources. They also pose safety risks when collided or overheated. Flexible organic materials are naturally stable, with a low risk of combustion or explosion, and their synthesis and recycling are more convenient. Additionally, their flexibility makes them an ideal choice for wearable devices.
Previously, organic materials faced technical bottlenecks such as poor conductivity, requiring large amounts of conductive additives, and small-molecule organic compounds easily dissolving in electrolytes, leading to shortened battery life. This study is considered a key step in promoting organic batteries from the laboratory to practical applications.
