Chinese Researchers Develop Lithium Battery Achieving 700 Wh/kg with Innovative Fluorinated Electrolytes
A new lithium battery electrolyte developed by researchers from Nankai University can achieve 700 Wh/kg at room temperature, more than double current commercial technologies. This innovation involves using fluorinated hydrocarbon solvents instead of traditional carbonate-based ones, which allows for improved lithium-fluorine coordination.
Tests show that at -50°C, these batteries maintain approximately 400 Wh/kg, outperforming existing lithium-ion batteries. The research team is also partnering with Hongqi to develop a mass-producible solid-liquid battery system with over 500 Wh/kg energy density. The implications extend to various applications in extreme conditions, though manufacturing and environmental impacts of the new electrolytes need further exploration.
