Summary: The ternary nanocomposites based on multi-walled carbon nanotubes, polyaniline, and sulfonated graphene nanopowders exhibited improved structural characteristics and enhanced electrochemical performance in supercapacitor electrodes. The functionalization of sulfonated graphene's surface contributed to less agglomeration, a high interlayer distance between nanoparticles, and better conductivity and capacitance properties. The ternary s-GN/CNTs@PANI nanocomposites demonstrated superior performance in terms of conductivity, resistivity, and pseudo-capacitive behavior compared to PANI and CNTs@PANI.

Summary: This study utilized molecular dynamics simulation to investigate the structural and transport properties of ethaline and glyceline blended with Li+ based salt for electrolyte applications in lithium-ion batteries. It was found that Li+ ions are in diffusive regime at high temperature and low molar concentration. The self-diffusion coefficient of Li+ ion was observed to be tenfold higher in ethaline compared to glyceline at the same salt concentration.
