Designing anti-freezing electrolytes through choosing suitable H2O–solute systems is crucial for low-temperature aqueous batteries (LTABs). However, the lack of an efective guideline for choosing H2O–solute systems based on decisive temperature-limiting factors hinders the development of LTABs.
The design of the low-temperature electrolyte. (a) The break of hydrogen bonds in ice by the solvation of Zn2+ and Ca 2+ allows water molecules to remain liquid at low temperatures. The snapshot of the MD simulation of BE and LTAE-BH-3 M Ca2+ at 30 °C (b, c) and −50 °C (d, e). The red line represents the H-bonds.
The main challenges of low temperature aqueous batteries (LT-ABs) are electrolyte freezing, slow ionic diffusion and sluggish interfacial redox kinetics at low temperature [7, 8], which are closely related to physicochemical properties of low temperature aqueous electrolytes (LT-AEs).
This work demonstrates that the LTAE-BH-3 M Ca 2+ has application prospect in low-temperature Zn metal battery, and the phase diagrams guided design may lighten a rational synthetic strategy of low-temperature electrolyte for other low-temperature aqueous batteries.
To construct low-temperature aqueous Zn batteries, people have proposed some strategies to lower phase transition temperature (T m). According to the thermodynamic theory, the Gibbs free energy difference is zero at Tm. Therefore, the T m depends on the ratio of ΔH and ΔS as denoted in Eq. (1).
Low temperature aqueous batteries (LT-ABs) have attracted extensive attention recent years. The LT-ABs suffer from electrolyte freezing, slow ionic diffusion and sluggish interfacial redox kinetics at low temperature.
