摘要: Abstract Nanostructured magnesium nickel oxide Mg0.6Ni0.4O and alumina Al2O3 were studied as additives to sulphur/polyaniline (S/PANI) composites via wet ball-milling of sulphur polyaniline followed by heat treatment. Metal nanoparticles, which have small particle size, porous structure high specific surface area volume ratio, are expected be catalytic for chemical reactions, including electron transfer able adsorb lithium polysulphides. The characterized SEM electrochemical methods. Cyclic voltammetry studies suggest that the additive acts differently Mg0.6Ni0.4O. results although improves S/PANI composite performance a lithium–sulphur battery cathode, use is more effective.
