Abstract:Lithium−sulfur (Li−S) batteries are perceived as a promising energy storage system for the next generation because of the advantages of high theoretical specific capacity and environmental friendliness. Whereas, challenges such as the poor conductivity of sulfur, the "shuttle effect" of polysulfides, and the sluggish redox kinetics of polysulfides in conversion reactions remain. Herein, the cubic shape of ZIF−67 was prepared, and Co-decorated carbon nanotubes covered on the nitrogen−carbon matrix (CoNC−CNT) an… Show more
