Phys.org  April 14, 2022 Low temperature aqueous batteries (LT-ABs) have attracted extensive attention in recent years. However, they suffer from electrolyte freezing, slow ionic diffusion and sluggish interfacial redox kinetics at low temperature. In a review article researchers in China discussed the physicochemical properties of aqueous electrolytes in terms of phase diagram, ion diffusion and interfacial redox kinetics to guide the design of low temperature aqueous electrolytes (LT-AEs). They introduced the characteristics of equilibrium and non-equilibrium phase diagrams to analyze the antifreezing mechanisms and propose design strategies for LT-AEs. To understand and regulate the ion diffusion kinetics they reviewed the […]
