Enhanced Electrochemical Kinetics on Ni ₂ P Polar Mediators Integrated with Graphene for Lithium–Sulfur Batteries

Lithium-sulfur batteries have evoked intensive attention caused by the urgent requirement of energy storage devices with higher density, long cycle life, and low cost. However, insulating nature soluble reaction intermediate products still hinder its large-scale industry acceptance market. Tremendous efforts focus on composite polar material non-polar to solve weaknesses products. linkage form between these two generic materials has been ignored. In this paper, using typical Ni2P as graphene material, kinetics changes intrinsic theories behavior enhancement proved, which construct different binding type materials. The Ni2P/PrGO delivers an improved high specific capacity 1254.6 mAh g-1 than Ni2P/rGO at 0.2 C. relevant X-ray photoelectron spectroscopy result in situ electrochemical impedance tests prove that state strong influence sulfur cathode kinetics. enhanced adsorption bring soft pack battery testing unit over 150 stable cycles decay ratio 0.19% for each cycle.
