Poor cycling stability and mechanistic controversies have hindered the wider application of rechargeable aqueous Zn-MnO2 batteries. Herein, direct evidence was provided importance Mn2+ in this type battery by using a bespoke cell. Without pre-addition , cell exhibited an abnormal discharge-charge profile, meaning it functioned as primary battery. By adjusting content electrolyte, recovered its charging ability through electrodeposition MnO2 . Additionally, dynamic pH variation observed...

Potassium (K)-based batteries hold great promise for cryogenic applications owing to the small Stokes radius and weak Lewis acidity of K+. Nevertheless, energy-dense (>200 W h kg–1cathode+anode) K under subzero conditions have seldom been reported. Here, an over 400 kg–1cathode+anode battery is realized at −40 °C via anode-free dual-ion strategy, surpassing these state-of-the-art even most Li/Na low temperatures (LTs). By introduction a strongly associating salt as additive this battery,...

Conventional electrode preparation techniques of supercapacitors such as tape casting or vacuum filtration often lead to the restacking agglomeration two‐dimensional (2D) materials.
