Lithium-sulfur batteries have high promise for application in next-generation energy storage. However, further advances have been hindered by various intractable challenges, particularly three notorious problems: the “shuttle effect”, sluggish kinetics...
A Ni–Al layered double hydroxide (LDH)–graphene superlattice composite via alternating assembly of the exfoliated thin flakes with opposite charges is constructed for high-rate alkaline secondary battery cathode material.
