What is polarized gel electrolyte of polyacrylamide-sodium citric (Pam-SC)?

Gel electrolyte is one of the most important components in FZABs, which is urgent to be optimized to match with Zn anode and adapt to severe climates. In this work, a polarized gel electrolyte of polyacrylamide-sodium citric (PAM-SC) is designed for FZABs, in which the SC molecules contain large amount of polarized −COO − functional groups.

What is the ionic conductivity of gel polymer electrolytes?

Moreover, the gel polymer electrolyte exhibits poor ionic conductivity at low temperatures (<1 mS cm −1 at zero). Apart from PC-based gel polymer electrolytes, water is another commonly used solvent for gel electrolytes (hydrogel electrolytes) due to the high dielectric constant (ε = 78.5).

What is gel polymer electrolyte?

This type of gel electrolyte is also called gel polymer electrolyte. A large amount of organic solvent and plasticizers make it flammable and toxic. Moreover, the gel polymer electrolyte exhibits poor ionic conductivity at low temperatures (<1 mS cm −1 at zero).

Can hydrogel electrolytes solve zinc anodes?

Gel electrolytes have attracted extensive attention in flexible batteries. However, the traditional hydrogel electrolyte is not enough to solve the fundamental problems of zinc anodes, such as dendrite growth, side reactions, and freezing failure at temperatures below zero, which seriously restricts the development of zinc-ion batteries.

Are poly–caprolactone nanofibrous a flexible electrochromic energy-saving window?

Flexible electrochromic energy-saving windows with fast switching and bistability based on a transparent solid-state electrolyte Mater. Chem. Front., 3 ( 2019), pp. 2514 – 2520 Poly-ε-caprolactone nanofibrous mats as electrolyte host for tailorable flexible electrochromic devices Mater. Sci. Eng. B, 241 ( 2019), pp. 36 – 41

Do polarized COO functional groups in gel electrolyte suppress Zn dendrite growth?

The polarized −COO − functional groups in gel electrolyte not only form an electrical field to suppress Zn dendrite growth, but also prevent water from freezing and evaporating. The FZABs with the PAM-SC gel electrolyte exhibit long cycling life of 700 cycles at −40 °C, showing the application prospect under extreme conditions.
