Abstract Zinc‐based electrochemistry is attracting significant attention for practical energy storage owing to its uniqueness in terms of low cost and high safety. However, the grid‐scale application plagued by limited output voltage inadequate density when compared with more conventional Li‐ion batteries.

Dendrite growth and by-products in Zn metal aqueous batteries have impeded their development as promising energy storage devices. We utilize a low-cost additive, glucose, to modulate the typical ZnSO4 electrolyte system for improving reversible plating/stripping on anode high-performance ion (ZIBs). Combing experimental characterizations theoretical calculations, we show that glucose environment can simultaneously solvation structure of Zn2+ anode-electrolyte interface. The engineering...

While research interest in aqueous batteries has surged due to their intrinsic low cost and high safety, the practical application is plagued by restrictive capacity (less than 600 mAh g–1) of electrode materials. Sulfur-based (SABs) feature theoretical (1672 g–1), compatible potential, affordable cost, arousing ever-increasing attention intense efforts. Nonetheless, underlying electrochemistry SABs remains unclear, including complicated thermodynamic evolution insufficient kinetics metrics....
We propose an objective Mn-based competitive capacity evolution protocol and a recusing strategy for dead Zn-ion batteries. The findings would provide new insights to understand the electrochemical behaviors more comprehensively.
The bias of Ni–Zn batteries between practical applications with gravimetrical limits and scientific research volumetrical shortages has been corrected.
Zn-based aqueous batteries (ZABs) have been regarded as promising candidates for safe and large-scale energy storage in the "post-Li" era. However, kinetics stability problems of Zn capture cannot be concomitantly regulated, especially at high rates loadings. Herein, a hierarchical confinement strategy is proposed to design zincophilic spatial traps through host porous Co-embedded carbon cages (denoted CoCC). The Co sites act preferred nucleation with low barriers (within 0.5 mA h cm-2),...
