“…Notable examples are alkaline zinc and zinc-air batteries and hydroxide-exchange membrane fuel cells (HEMFC). [58,59] When compared to CEMs, AEMs usually possess higher electrical resistance and a lower conductivity, due to the lower anion mobility. [60] Furthermore, CEMs are mostly commercially available and exhibit a high variability in structure and good chemical stabilities.…”

both large-and small-scale energy storage, ranging from large pumped hydroelectric storage to very small battery cells for handheld devices.Secondary batteries are among the more promising energy storage technologies, with a wide range of applications. [4] Since the development of the lead acid battery in the second half of the 19th century (Gaston Planté, 1860), a broad range of batteries has been invented. [5] Notable examples are the nickel/cadmium cell (1899) [6] and the lithium-ion battery, which was developed in the 1970s. [7] Today, batteries are omnipresent in the everyday lives of a large part of the world's population. They find application in numerous fields, ranging from handheld or portable devices to electric vehicles (including vehicles with combustion engines) to large-scale energy storage for renewable sources. [8] Each field has unique requirements for the applied batteries, therefore different battery types have been developed to meet the demands.The most dominant type of secondary batteries for modern devices is the lithium-ion battery. Lithium-ion batteries possess high energy densities, good rate capabilities, and a long cycle life. Since their commercialization in 1991, they have been applied in many portable devices, electric vehicles and even in large-scale energy storage systems. [7] Since 2000, the share of the worldwide produced lithium for application in batteries (35% of the total production in 2015) has increased by 20% per year. [9] Another, less known battery type is the redox-flow battery (RFB). With their independent scalability of capacity and power, they are in particular interesting for large-scale storage of renewable energy with regard to grid stability. [10] A recent, so far not commercially available type of batteries is the organic battery. Here, an organic compound (small molecule or polymer) is responsible for charge storage. Organic batteries offer high rate capabilities, cheap starting materials, and are less environmentally challenging compared to metalbased batteries. Possible fields of application are small, lightweight, and easily recyclable products. [11] None of the above-mentioned batteries would work without polymers. Polymers can be found in the electrodes, where they act as binders, ensuring a good adhesion and contact among the different materials. Furthermore, many membranes are based on polymers. Here, the macromolecules have to be ionconducting as well as mechanically and chemically robust. In addition, organic batteries rely on polymeric active materials. This review discusses the diverse possibilities polymers haveIn the light of an ever-increasing energy demand, the rising number of portable applications, the growing market of electric vehicles, and the necessity to store energy from renewable sources on large scale, there is an urgent need for suitable energy storage systems. In most batteries, the energy is stored by exploiting metals or metal-ion-based reactions. However, nearly every modern battery would not function without the help of polymer...

The amount of fresh water used in hydraulic fracturing can be significantly reduced by employing produced water-compatible supercritical CO 2 (scCO 2 ) foams. Foams generated using surfactants only have suffered from long-term stability issues resulting in low viscosity and proppant-carrying problems. In this work, foam lamella stabilization with polyelectrolyte complex nanoparticles (PECNPs) and wormlike micelles (WLMs) is investigated. Electrostatic interactions are studied as the defining factors improving the hydraulic fracturing performance using the PECNP system prepared in produced water. Two oppositely charged polyelectrolytes are investigated to generate a more stable lamellae between the aqueous phase and the scCO 2 while degrading in the presence of crude oil. The generated dry foam system is used as a hydraulic fracturing fluid in a tight shale formation. The strong compatibility of the synthesized PECNPs with zwitterionic surfactants prepared in highly concentrated brine in the form of wormlike micelles above critical micelle concentration (CMC) helps develop a highly viscous, dry foam capable of using produced water as its external phase. This foam system improves fracture propagation and proppant transport fracture cleanup compared to the base case foam system with no PECNPs. The formation of PEC−surfactant nanoparticles was verified via zeta potential, particle size analysis, and transmission electron microscopy; the underlying mechanism was identified as electrostatic rearrangement of WLMs along the PECNP's perimeter or formation of electrostatically bonded micelles with the nanoparticle to create a new enhanced nanoparticle. A Raman spectroscopic model was developed to understand the PECNP−surfactant spectra and subsequent spectroscopic and hence structural changes associated with complexation. Enhanced bulk viscosity and improved foam quality as a result of complexation at the interface was identified with rheometry in addition to sand pack experiments with PECNP−surfactant ratios of 1:9 and 4:6 in 33.3 kppm and 66.7 kppm salinity brine systems, respectively. Enhancement in the shear thinning and cleanup efficiency of the fracturing fluid was observed. Formation damage was controlled by the newly introduced mixtures as fluid loss volume decreased across the tight Kentucky sandstone cores by up to 78% and 35% for scCO 2 foams made with PECNP−WLMs in 33.3 and 66.7 kppm salinity brine, respectively. The produced water compatibility and reduction of water disposal presented the prospect of environmentally friendly scCO 2 foams for hydraulic fracturing of unconventional reservoirs.

In this work, two-component fibrous separators with high electrolyte absorption were fabricated by the delamination of oriented polymer tape which was produced using a unique coextrusion and multiplication process. Two different separators were created from polypropylene/high-density polyethylene (PP/HDPE) and polypropylene/polyamide 6 (PP/PA6) by this process. The separators have a pore size of 10 μm, high porosity, and high surface area. The electrolyte absorption (KOH uptake) of PP/HDPE separators and PP/PA6 separators are almost 3 times higher than that of commercial separators. The battery performance of the PP/HDPE separators and the PP/PA6 separators were evaluated in a coin cell battery configuration. The charge−discharge efficiency of coin cells made from the PP/PA6 separator is found to be 6% higher than the commercial separators.
