Novel, noble-metal-free, solid-state all-titanium carbide (Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>) MXene microsupercapacitors are fabricated, which exhibit high areal capacitance, excellent rate-capability, and transferable to any surface.
Understanding the rheological properties of two-dimensional (2D) materials in suspension is critical for development various solution processing and manufacturing techniques. 2D carbides nitrides (MXenes) constitute one largest families with >20 synthesized compositions applications already ranging from energy storage to medicine optoelectronics. However, spite a report on clay-like behavior, not much known about their response. In this study, behavior single- multilayer Ti3C2T x aqueous...
This paper presents a 2-D transient, isothermal model of vanadium redox flow battery that can predict the species crossover and related capacity loss during operation. The incorporates transport across membrane due to convection, diffusion, migration, accounts for transfer water between half-cells capture change in electrolyte volume. also side reactions associated changes concentration each half-cell crossover. A set boundary conditions based on conservations flux current are incorporated...
The discovery of liquid crystalline (LC) phases in dispersions two-dimensional (2D) materials has enabled the development macroscopically aligned three-dimensional (3D) macrostructures. Here, we report first experimental observation self-assembled LC aqueous Ti3C2T x MXene inks without using additives, binders, or stabilizing agents. We show that transition concentration from isotropic to nematic phase is influenced by aspect ratio flakes. formation makes it possible produce fibers MXenes a...
Abstract Availability of grid‐scale electric energy storage systems with response rates on the order seconds plays a key role in wide implementation renewable sources. Here, new concept called electrochemical flow capacitor (EFC) is presented. This shares major advantages both supercapacitors and batteries, providing rapid charging/discharging while enabling decoupling power ratings. Like supercapacitors, stored double layer charged carbon particles. A flowable carbon‐electrolyte mixture...
A major issue with the existing vanadium redox flow battery (VRFB) models is inaccurate prediction of open circuit voltage (OCV), which results in a discrepancy 131 to 140 mV predicted cell voltages when compared experimental data. This deviation shown be caused by incomplete description electrochemical double layers within calculating OCV using Nernst equation adopted from fuel literature. Here, we propose more complete equation, accounts for two additional mechanisms that exist VRFB,...
Flow electrode deionization (FCDI) is an emerging area for continuous and scalable deionization, but the electrochemical flow properties of need to be improved minimize energy consumption. Chemical oxidation granular activated carbon (AC) was examined here study role surface heteroatoms on rheology performance a (carbon slurry) processes. Moreover, it demonstrated that higher mass densities could used without increasing pumping when using oxidized active material. High mass-loaded electrodes...
In this study, we investigate the mass transport effects of various flow field designs paired with raw and laser perforated carbon paper electrodes in redox batteries (RFBs). Previously, observed significant increases peak power density limiting current when were used conjunction serpentine field. work, expand on our earlier findings by investigating (e.g., serpentine, parallel, interdigitated, spiral), continuously measuring pressure drop each configuration. all cases, these are found to be...
In order to understand the properties of low vanadium permeability anion exchange membranes for redox flow batteries (VRFBs), quaternary ammonium functionalized Radel (QA-Radel) with three ion capacities (IECs) from 1.7 2.4 mequiv g–1 were synthesized and 55–60 μm thick membrane samples evaluated their transport in-cell battery performance. The ionic conductivity investigated correlated performance through measurements Coulombic efficiency, voltage efficiency energy in single cell tests,...
