Aqueous Zinc‐Based Batteries: Active Materials, Device Design, and Future Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
This review conducts a comprehensive analysis of aqueous zinc‐based batteries (AZBs) based on their intrinsic mechanisms, including redox reactions, ion intercalation reactions, alloying reactions, electrochemical double‐layer reactions, and mixed mechanisms, systematically discussing recent advancements in each type of AZBs.

Development of anion-exchange membrane for anion-exchange membrane fuel cells

Materials Research Innovations, 2015
Anion-exchange membrane fuel cells possess several important advantages, and have attracted a lot of attention. In this paper, the characteristic of different type anion-exchange membrane were introduced. In view of the ion conductivity and stability of anion-exchange membrane, these anion-exchange membranes based on polybenzimidazole ...

Metal-Cation-Based Anion Exchange Membranes

Journal of the American Chemical Society, 2012
Here we present the first metal-cation-based anion exchange membranes (AEMs), which were synthesized by copolymerization and cross-linking of a norbornene monomer functionalized with a water-soluble bis(terpyridine)ruthenium(II) complex and dicyclopentadiene. Each ruthenium complex has two associated counteranions, unlike most ammonium- and phosphonium-

Microheterogeneity of anion exchange membranes

Journal of Applied Polymer Science, 1975
Anion exchange membranes (ferricyanide ion type) prepared by the “paste method” were treated with an aqueous solution of hydrogen peroxide, and the resultant microporous membranes had no ion exchange capacity but water permeability. By measuring the water permeability of the membranes and observing the electron microphotographs of the membrane surfaces,

Nitrate-selective anion-exchange membranes

Journal of Membrane Science, 1988
Abstract A nitrate-specific anion-exchange membrane was obtained by suitable amination of bromomethylated polysulfone blended with polysulfone. The presence of a tertiary amine is required. In transport from aqueous solutions containing a 7-fold excess of chloride ions over nitrate ions, nitrate flux is larger than chloride flux by a factor of two as

One-Pot Synthesis of Proton Exchange Membranes from Anion Exchange Membrane Precursors

ACS Macro Letters, 2020
Proton exchange membranes (PEMs) play a critical role in many electrochemical devices that could solve the shortcomings of current energy storage and conversion systems. Hydrocarbon-based PEMs are an attractive alternative for replacing the state-of-the-art perfluorosulfonic acid PEMs; however, synthetic routes are generally limited to sulfonation of ...

(Invited) Anion Exchange Membranes

ECS Meeting Abstracts, 2019
I didn't think I was going to work on anion exchange membranes until Shimshon gave me a call in early 2008 wanting to talk about quaternary ammonium-containing polymers. It has been an interesting journey since then. CellEra's support allowed me to hire my first postdoc - Jingling Yan - and also introduced me to a great cast of characters including ...

3D Printing of Micropatterned Anion Exchange Membranes

ACS Applied Materials & Interfaces, 2016
Micropatterned anion exchange membranes (AEMs) have been 3D printed via a photoinitiated free radical polymerization and quaternization process. The photocurable formulation, consisting of diurethane dimethacrylate (DUDA), poly(ethylene glycol) diacrylate (PEGDA), dipentaerythritol penta-/hexa- acrylate, and 4-vinylbenzyl chloride (VBC), was directly ...
