Microstructural tunability of co-continuous bijel-derived electrodes to provide high energy and power densities

Abstract

Bijel processing provides a unique route to energy materials with co-continuous microstructure and tunable electrochemical properties for simultaneous delivery of large power and energy densities.

Ultrahigh Energy Absorption Multifunctional Spinodal Nanoarchitectures

“…Nanospinodals have recently been demonstrated to be orders of magnitude more scalable than additively manufactured nanolattices. Graphene and nickel nanospinodals with millimeter‐size overall dimensions, yet nanometer‐size features were fabricated via dealloying and polymeric Bijel templates, respectively . The results of this study demonstrate that such spinodal architectures are an ideal platform for the next generation of superior cellular materials for structural applications and impact protection systems.…”

“…Today, industrial application of architected materials (even with macroscopic topological features) is hindered by manufacturing limitations. By contrast, spinodal decomposition of a template material followed by material conversion may be a manufacturing route competitive with state‐of‐the‐art foam production . Nanospinodals have recently been demonstrated to be orders of magnitude more scalable than additively manufactured nanolattices.…”

Bijels formed by direct mixing

“…The list of potential bijel applications includes use as a template for catalysts, electrodes for batteries and fuel cells, hierarchically porous materials, scaffolds for tissue engineering and cross-flow microreactors. [4][5][6][7][8] Initially, bijels were experimentally realised using partially miscible liquids which, when quenched, can phase separate via spinodal decomposition forming a bicontinuous arrangement of fluid domains. 9 As phase separation begins the particles are swept onto the interface, with time the fluid domains coarsen and the amount of interfacial area decreases.…”

Electrostatic‐Driven Dynamic Jamming of 2D Nanoparticles at Interfaces for Controlled Molecular Diffusion

“…[1,2] Inspired by nature,t he active assembly of nanoparticles (NPs) at interfaces has drawn significant interest in developing NP-stabilized heterophasic systems at multiple length scales,f rom the microscopic control of polymer morphologies [3] to themacroscopic fabrication of interconnected bijels. [4] These NP-stabilized structures enable superior properties for many applications such as design of high-efficient catalysts, [5] fabrication of electrodes, [6] and manufacture of scaffolds. [7] Furthermore,the ability of NPs to regulate the shapes of multiphasic systems and the possibility of nanomaterials to precisely manipulate surface properties of emulsions may also promote novel synthetic techniques,f or example,s hape-memory organohydrogel materials.…”
