TL;DR: In this article, a review summarizes the current uses of graphene-based materials in high performance electrode material preparation and device configuration, and more importantly, the challenges of graphene for practical use in these devices.

TL;DR: In this article, a hierarchical porous graphene macrostructure coupled with uniformly distributed α-Fe2O3 nano-particles (denoted Fe-PGM) was designed as a sulfur host in a lithium-sulfur battery, and was prepared by a hydrothermal method.

TL;DR: The first gelation of MXenes in an aqueous dispersion that is initiated by divalent metal ions is reported, where the strong interaction between these ions and OH groups on the MXene surface plays a key role.

TL;DR: It is pioneeringly demonstrated that decorating the Zn surface with a dual-functional metallic indium (In) layer, acting as both a corrosion inhibitor and a nucleating agent, is a facile but effective strategy to suppress both drastic corrosion and dendrite growth.

TL;DR: How a bidirectional catalyst works for boosting Li-S batteries approaching practical uses is unlocked, indicating a fundamental way for improving both the cycling stability and sulfur utilization.
