LiFEES, conductive salt for lithium-ion batteries / accumulators

Summary

Fluorinated ethanesulfonate derivative/ conductive salt for lithium-ion batteries.

Technology Benefits

High thermal stability
Wide temperature range
Better performance
Lower toxicity

Technology Application

Lithium ion batteries are widely used as mobile energy storage.

Detailed Technology Description

The invention describes a fluorinated ethanesulfonate derivative and its use as a conductive salt for lithium-ion batteries. In contrast to LiPF6, similar to LiB8, the leading electrolyte shows a higher thermal stability and lower toxicity of the combustion products. This provides a wider temperature range, e.g. For lithium-ion batteries with comparable performance possible.
