“…In operation, type III systems rely on the collisions of active material particles with the current collector and have very low electrochemical activity in the absence of flow. 147,148 This type of carbon-free active material suspension as an energy containing fluid has been explored for both Li-ion materials and polymer suspension based cells, [147][148][149][150][151][152][153] and the chemistry of the active materials will be discussed in more detail in Sec. III.…”

Energy storage is increasingly important for a diversity of applications. Batteries can be used to store solar or wind energy providing power when the Sun is not shining or wind speed is insufficient to meet power demands. For large scale energy storage, solutions that are both economically and environmentally friendly are limited. Flow batteries are a type of battery technology which is not as well-known as the types of batteries used for consumer electronics, but they provide potential opportunities for large scale energy storage. These batteries have electrochemical recharging capabilities without emissions as is the case for other rechargeable battery technologies; however, with flow batteries, the power and energy are decoupled which is more similar to the operation of fuel cells. This decoupling provides the flexibility of independently designing the power output unit and energy storage unit, which can provide cost and time advantages and simplify future upgrades to the battery systems. One major challenge of the existing commercial flow battery technologies is their limited energy density due to the solubility limits of the electroactive species. Improvements to the energy density of flow batteries would reduce their installed footprint, transportation costs, and installation costs and may open up new applications. This review will discuss the background, current progress, and future directions of one unique class of flow batteries that attempt to improve on the energy density of flow batteries by switching to solid electroactive materials, rather than dissolved redox compounds, to provide the electrochemical energy storage.

“…Polyaniline has been an important member in the ICP family, owing to its easy preparation, excellent environmental stability, various forms, interchangeable oxidation states, electrical and optical properties, and low cost [1][2][3]. It has various potential applications in many high-performance devices such as rechargeable batteries [4], chemical sensors [5], electrochemical and corrosion devices [6,7] organic light emitting diodes (OLEDs) [8], field-effect transistors (OFETs) [9], and solar cells [10][11][12]. The common synthesizing method of conducting polymers is, namely, the chemical oxidative [13] or electrochemical [14] polymerization.…”

Conducting polymer poly(O-toluidine) (POT) doped with dodecyl benzene sulfonic acid was prepared by the chemical polymerization with the help of ammonium persulphate (NH4)2S2O8 as an oxidizing agent. This polymer was blended with different weight ratios (0%, 10%, 15%, 25%, 35%, 45%, 50%) of poly(ethylene oxide) (PEO) to produce nano conducting polyblend POT-DPSA/PEO, prepared by the spin coating method, and deposited on a glass substrate. The surface morphology was studied by scanning electron microscope. The optical properties of a prepared film was studied from the absorbance spectra at wavelengths 300-1100 nm. The analysis of optical measurement data shows the direct transition with the energy gap decreasing from 2.80 eV to 2.25 eV, as the content of PEO increases from 0% to 50%.

“…Zinc is widely used as a negative electrode material of batteries (such as Zn-Mn and Zn-Ag batteries) owing to the advantages of low equilibrium potential, high specific energy density, being an abundant resource, having low cost, and being environmentally friendly [3]. Conducting polymer polyaniline (PANI) [4,5] has attracted researchers' interest as a cathode active material of rechargeable batteries in aqueous [6][7][8] and non-aqueous electrolytes [9][10][11][12] (such as Zn-PANI secondary battery [13][14][15][16][17] and Li-PANI secondary battery [18][19][20]). A significant portion of these studies has been devoted to PANI that exhibit excellent electrochemical activity and environmental stability.…”

Zinc is widely used as a negative electrode material for batteries due to its excellent electrochemical properties. Zinc is prone to corrosion and the formation of zinc dendrites cause short circuits of the battery, which leads to reduced battery capacity and shortens the battery's life, hindering its use in weak acidic electrolytes (for example, aqueous Zn-polyaniline batteries). The effects of carboxylates (sodium formate, sodium acetate, sodium propionate, sodium butyrate, sodium valerate, disodium malonate, and disodium succinate) and their concentrations on zinc electrode performance were studied with electrochemical methods to improve the zinc electrode activity for long-life Zn-polyaniline batteries. It was found that the ability of inhibiting corrosion of the zinc electrode is better in the aqueous electrolyte containing 0.2 M disodium malonate. The charge/discharge performance of a Zn-polyaniline battery electrodeposited with polyaniline on a carbon substrate is carried out in the aqueous electrolyte. the results show that the initial discharge specific capacity of the polyaniline in the Zn-polyaniline battery is as high as 131.1 mAh¨g´1, and maintains a discharge specific capacity of 114.8 mAh¨g´1 and a coulombic efficiency over 92% after 100 cycles at a charge/discharge current density of 1 A¨g´1 in the voltage range of 1.5-0.7 V.
