High interconversion energy barriers, depressive reaction kinetics of sulfur species, and sluggish Li+ transport inhibit the wide development high-energy-density lithium (Li-S) batteries. Herein, differing from random mixture selected catalysts, composite catalyst with outer delocalized isoelectronic heterostructure (DIHC) is proposed optimized, enhancing catalytic efficiency for decreasing related barriers. As a proof-of-content, FeCoOx Sy composites different degrees sulfurization are...
Growth of dendrites, limited coulombic efficiency (CE), and the lack high-voltage electrolytes restrict commercialization zinc batteries capacitors. These issues are resolved by a new electrolyte, based on zinc(II)-betaine complex [Zn(bet)2 ][NTf2 ]2 . Solutions in acetonitrile (AN) avoid dendrite formation.
