S@NiS Hollow Spheres as Cathode Materials for LithiumSulfur Batteries
International Journal of Electrochemical Science, 2019 Severe capacity fading substantially hinders the employment of lithium-sulfur batteries in the electric vehicles. This is primarily due to the shuttle effect of the polysulfide in the electrolyte. Therefore, the most efficient method to improve the cycle
