Outline of Research at the Start

The successful operation of this project would promote a high-energy lithium-sulfur batteries working at extreme temperatures, which might be applied in a wide spectrum of applications. The critical electrolyte can make greact inpact on the battery stability at extreme temperatures.

Outline of Annual Research Achievements

1.The formulated electrolyte can satisfy the demands of working at high-temperature (80 degree) for lithium-sulfur batteries, without sacrificing the cyclic stability.
2. The formulated electrolyte can work at a wide range of temperatures (-40 to 80 degree) for lithium-sulfur batteries.
3. The designed electrolyte exhibits great potential in some functional devices working at extreme conditions.
