Qingtao Energy has developed a perfluorinated polyether-based positive electrode film additive suitable for halide-based solid-state batteries.

On April 21, according to Qingtao Energy, the research and development team of Qingtao Energy first proposed the concept of halide-based synergistic composite cathode, and developed a perfluoropolyether cathode film additive suitable for halide-based solid-state batteries. In the composite cathode, by constructing a stable and ion-conducting cathode electrolyte interface layer, the interface contact and ion transport between particles have been significantly improved, thereby significantly improving the capacity performance, rate performance, and cycle stability of the battery. The related research results were published online in the journal "Advanced Energy Materials" on April 20.
