“…In this model, the viscosity coefficient, activation energy, and Gibbs free energy of activation were integrated for better accuracy and adaptability. Guo et al [ 94 ] then developed semi-empirical equations for the viscosity of VOSO 4 ·PAA·H 2 O ternary solutions at different temperatures, from 283.15 K to 318.15 K, and ionic strengths, and the equations were in good agreement with the experiment results. Moreover, the viscosity of this system descends with the rising temperature and significantly ascends with the rising concentration of PAA.…”

Vanadium redox flow batteries (VRFBs) are promising candidates for large-scale energy storage, and the electrolyte plays a critical role in chemical–electrical energy conversion. However, the operating temperature of VRFBs is limited to 10–40 °C because of the stability of the electrolyte. To overcome this, various chemical species are added, but the progress and mechanism have not been summarized and discussed yet. This review summarizes research progress on electrolyte additives that are used for different purposes or systems in the operation of VRFBs, including stabilizing agents (SAs) and electrochemical mass transfer enhancers (EMTEs). Additives in vanadium electrolytes that exhibit microscopic stabilizing mechanisms and electrochemical enhancing mechanisms, including complexation, electrostatic repulsion, growth inhibition, and modifying electrodes, are also discussed, including inorganic, organic, and complex. In the end, the prospects and challenges associated with the side effects of additives in VRFBs are presented, aiming to provide a theoretical and comprehensive reference for researchers to design a higher-performance electrolyte for VRFBs.

“…PI and PVDF 18 have weak binding forces with inorganic materials, PE has weak oxidation resistance and poor mechanical properties and PAA is easily hydrolyzed. 19 It has been proved that the surfaces of atmospheric PM contain a variety of strong polar functional groups, so the dipole moment of the polymer repeating unit plays an important role in the removal of atmospheric PM. Comparisons of units of various polymers show that PAN exhibits the largest dipole moments.…”

As many countries in the world are paying increasing attention to air quality, reducing the concentration of pollutants in the air, protecting human health and improving the ecological environment have become problems that need to be solved urgently. This paper describes how ceria and cobalt tetroxide@polyacrylonitrile (CeO2/Co3O4@PAN) nanofiber membranes are produced using electrospinning technology, which have broad applications for the removal of air pollutants. Results show that CeO2/Co3O4@PAN has high electrostatic attraction to particulate matter (PM). CeO2/Co3O4@PAN membranes show better mechanical properties, thermal stability and air-purification performance than pure PAN membranes. Nanofiber membranes with 5 wt% of CeO2/Co3O4 have excellent removal efficiency: 93.4% and 94.5% for PM2.5 and PM10, respectively, and 96.2% and 98% for formaldehyde and total volatile organic compounds, respectively. They also show low pressure drops, high stability and good recyclability. This work shows that they are promising candidates as highly stable, recyclable and efficient agents for the removal of air pollutants.
