摘要

本研究调查了Carbopol®和锌微颗粒之间的相互作用,以及它们在锌浆-空气氧化还原液流电池(Zn-air RFBs)框架内稳定锌的作用。该研究探讨了屈服应力流体,特别是 PAA(Carbopol®)微凝胶在电池运行期间作为锌微粒稳定剂的潜力,尤其是在沉积方面。本研究考察了两种可能限制 PAA 屈服应力稳定悬浮液效果的影响。首先是离子强度和 pH 值,它们会在浆料配制过程中发生变化。第二种影响与悬浮液制备过程中可能产生的锌聚合物相互作用有关。通过使用基于流变仪和紫外可见光谱的方法,研究发现稳定化的主要挑战在于Carbopol®微凝胶对锌表面的吸附,这极大地影响了凝胶的屈服应力。这些见解有助于加深对悬浮液物理化学的理解,从而促进更高效、更稳定的锌-空气 RFB 的开发。

Investigating the interactions between Carbopol® and zinc particles within the context of a zinc-air redox flow batteries application

This research investigates the interactions between Carbopol® and zinc microparticles and their role in the stabilization of zinc within the framework of zinc slurry–air redox flow batteries (Zn-air RFBs). The study explores the potential of yield stress fluids, particularly PAA (Carbopol®) microgels, as stabilizers for zinc particles during battery operation, and regarding sedimentation in particular. Two effects that can limit the effectiveness of PAA yield stress in stabilizing the suspension are examined in this study. First is the ionic strength and pH that can evolve during the slurry formulation. The second effect is associated to zinc polymer interactions that can develop during the suspension preparation. Using methodologies based on rheometry and UV–Vis spectroscopy, the research identifies that the primary stabilization challenge is the adsorption of Carbopol® microgels onto zinc surfaces, which significantly influences the gel’s yield stress. These insights contribute to an enhanced understanding of the physical chemistry of the suspending fluid, facilitating the development of more efficient and stable Zn-Air RFBs.

期刊介绍: "Rheologica Acta is the official journal of The European Society of Rheology. The aim of the journal is to advance the science of rheology, by publishing high quality peer reviewed articles, invited reviews and peer reviewed short communications. The Scope of Rheologica Acta includes: - Advances in rheometrical and rheo-physical techniques, rheo-optics, microrheology - Rheology of soft matter systems, including polymer melts and solutions, colloidal dispersions, cement, ceramics, glasses, gels, emulsions, surfactant systems, liquid crystals, biomaterials and food. - Rheology of Solids, chemo-rheology - Electro and magnetorheology - Theory of rheology - Non-Newtonian fluid mechanics, complex fluids in microfluidic devices and flow instabilities - Interfacial rheology Rheologica Acta aims to publish papers which represent a substantial advance in the field, mere data reports or incremental work will not be considered. Priority will be given to papers that are methodological in nature and are beneficial to a wide range of material classes. It should also be noted that the list of topics given above is meant to be representative, not exhaustive. The editors welcome feedback on the journal and suggestions for reviews and comments."
