High-Energy-Density, Long-Life Lithium–Sulfur Batteries with Practically Necessary Parameters Enabled by Low-Cost Fe–Ni Nanoalloy Catalysts

Lithium–sulfur (Li–S) batteries possess excessive theoretical particular vitality however endure from lithium polysulfide (LiPS) shuttling and sluggish response kinetics. Catalysts in Li–S batteries are deemed as a cornerstone for bettering the sluggish kinetics and concurrently mitigating the LiPS shuttling. Herein, a cheap hexagonal close-packed (hcp)-phase Fe–Ni alloy is proven to function an environment friendly electrocatalyst … Read more
