The development of new energy vehicles, power grid energy storage, polar scientific research, deep space exploration and other fields has put forward higher requirements on the energy density and low-temperature performance of energy storage batteries.
In recent years, lithium metal batteries with metallic lithium with high theoretical specific capacity as negative electrodes have become one of the most promising high-energy-density battery systems.
However, due to the strong interaction between lithium ions and solvent in traditional ester-based electrolytes, the migration rate of lithium ions is slow and the stability of the electrode/electrolyte interface is poor, which limits the application of lithium metal batteries in low temperature environments.
According to foreign media reports, a research team led by Professor Li Feng of the Institute of Metal Research of the Chinese Academy of Sciences proposed an oxygen bond design strategy in the electrolyte, which achieved excellent performance of lithium metal batteries in low temperature environments.
The research result,”Designing Temperature-Insensitive Solved Electrolytes for Low-Temperature Lithium Metal Batteries”, was published as a cover paper in the journal Journal of the American Chemical Society.
