Rechargeable aqueous zinc‐ion batteries are practically plagued by the short lifespan and low Coulombic efficiency (CE) of Zn anodes resulting from random dendrite deposition and parasitic reactions. Herein, the host−guest chemistry of cucurbituril additive with Zn2+ to achieve longstanding Zn anodes is manipulated. The macrocyclic molecule of cucurbit[5]uril (CB[5]) is delicately designed to reconstruct...
The shuttle effect and sluggish redox kinetics of lithium polysulfides (LiPSs) severely hinder the scalable application of lithium‐sulfurr (Li–S) batteries. Herein, the highly dispersed α‐phase molybdenum carbide nano‐crystallites embedded in a porous nitrogen‐doped carbon framework (α‐MoC1−x@NCF) are developed via a simple metal–organic frameworks (MOFs) assisted strategy and proposed as the multifunctional...
Iron‐based sulfate cathodes of alluaudite Na2+2δFe2−δ(SO4)3 (NFS) in sodium‐ion batteries with low cost, steady cycling performance, and high voltage are promising for grid‐scale energy storage systems. However, the poor electronic conductivity and the limited understanding of the phase‐evolution of precursors hinder obtaining high‐rate capacity and the pure phase. Distinctive NFS@C@n%CNTs (n = 1,...
Photoresponsive nitric oxide (NO)‐releasing materials (NORMs) enable the spatiotemporal delivery of NO to facilitate their potential applications in physiological conditions. Here two novel metal–organic frameworks (MOFs)‐based photoactive NORMs achieved by the incorporation of prefunctionalized NO donors into the photosensitive Fe‐MOFs via a postmodification strategy is reported. The modified Fe‐MOFs...
Vanadium‐based oxides have attracted much attention because of their rich valences and adjustable structures. The high theoretical specific capacity contributed by the two‐electron‐transfer process (V5+/V3+) makes it an ideal cathode material for aqueous zinc‐ion batteries. However, slow diffusion kinetics and poor structural stability limit the application of vanadium‐based oxides. Herein, a strategy...
The stability of aqueous Zn‐ion batteries (AZIBs) is highly dependent on the reversibility of stripping/plating Zn anode. In this work, an organic ligand etching method is proposed to develop a series of in situ multifunctional protective layers on Zn anode. Particularly, the 0.02 m [Fe(CN) 6]3− etching solutions can spontaneously etch the Zn anode, creating an in situ protective layer with unique...
Rechargeable sodium ion batteries (SIBs) have promising applications in large‐scale energy storage systems. Iron‐based Prussian blue analogs (PBAs) are considered as potential cathodes owing to their rigid open framework, low‐cost, and simple synthesis. However, it is still a challenge to increase the sodium content in the structure of PBAs and thus suppress the generation of defects in the structure...
The comparatively poor endurance of Ni‐rich cathode materials restricts their application in high‐energy lithium‐ion batteries. A thorough understanding of the degradation characteristics of such materials under complex electrochemical aging protocols is required to further improve their reliability. In this work, the irreversible capacity losses of LiNi0.8Mn0.1Co0.1O2 under different electrochemical...

Prussian blue analogs (PBAs) have attracted wide interest as a class of ideal cathodes for rechargeable sodium‐ion batteries due to their low cost, high theoretical capacity, and facile synthesis. Herein, a series of highly crystalline Fe‐based PBAs (FeHCF) cubes, where HCF stands for the hexacyanoferrate, is synthesized via a one‐step pyrophosphate‐assisted co‐precipitation method. By applying this...
