A surfactant-modified composite separator for high safe lithium ion battery
The introduction of PAA/SDS enhances the adsorption energy between PTFE substrate and electrolyte through density functional theory calculations, which improves wettability and electrolyte uptake of the separator significantly. The battery with SDS/PAA/PTFE separator demonstrates a higher voltage sweep up to 5.4 V, as compared to 4.8 V for
