Long-duration aqueous manganese metal anode by hydrogel solvation regulation

The key challenge of implementing aqueous manganese (Mn) metal batteries is severe water-related parasitic reactions, including the hydrogen evolution reaction and Mn corrosion. These issues originate largely from the high reactivity of solvated water around manganese ions (Mn 2+...

Colloidal Electrolyte Enables Bulk-to-Interface Stabilization for Aqueous Manganese Metal Batteries

Abstract Aqueous Mn metal batteries combine the potential for high safety and energy density, yet are limited by high water activity, sluggish Mn2+ desolvation, and severe interfacial parasitic reactions, which cannot be resolved by isolated strategies. Here we develop an ether-o...
