In this context, we report a novel one-pot synthesis of S@Polypyrrole core–shell spheres as the cathode material in lithium–sulfur battery, designed by polypyrrole (PPy) wrapping on the formed nano-sulfur via the facile wet chemical strategy. The in-situ polymerized PPy layer in this special structure is helpful to inhibit aggregation of sulfur particles with small size, the polysulfide dissolution...
The effect of different structural designs on the performance of electrical double layer capacitors (EDLCs) has been studied through a mathematical model that considers the mass transfer and conservation of charge equations. The structural design parameters considered in this study are the electrode thickness, electrode porosity, and initial electrolyte concentration. The performance parameters studied...
