“…McBroom and McQuarrie (1987) reported the effect of the unequal size of the electrolyte on the electrostatic force between two planar surfaces Copyright 9 1992, The Clay Minerals Society in a 1:1 electrolyte using the nonlinear Poisson-Boltzmann equation. The prediction of a non-zero force between two uncharged walls was an interesting result.…”

“…We will use the unequal-radius-modified-GouyChapman (URMGC) approach to the interaction of two charged surfaces, introduced by McBroom and McQuarrie (1987), to describe the electrostatic interaction of two clay surfaces that are immersed in an electrolytic solution. First we consider a 1:1 electrolyte with an unequal-sized cation and anion.…”

Abstract--In this paper, we use the unequal radius modified Gouy-Chapman theory to evaluate the effect of the ionic size of the electrolyte on the swelling pressures (H) in different clay systems immersed in electrolytic solutions. First the model is applied to a l:l electrolyte to show that the coion size is only important at surface charge densities much lower than those found in typical clay systems. The swelling pressure is calculated and the results are compared with experimental data. Literature ionic radii values are used to show the dependence of the swelling pressure on the specific counterions present. Next the model is applied to a 1:1 and 2:1 electrolyte mixture with unequal-sized counterions to show the swelling pressure is highly dependent on both counterion sizes. The unequal and same-sized cases are compared.

The shortage of natural resources due to the progression of the human population and environmental pollution has become crucial concern topics to resolve. One of the best ways to resolve this is to develop renewable energy-based storage systems. Supercapacitors are emerging as promising storage systems via providing rapid charging/discharging and high power delivery, but there is a need to explore low-cost, environment-friendly, non-toxic, abundant, and biodegradable electrode materials for supercapacitors. In this regard, biopolymers are observed to be popular for storage applications as they are of high porosity, cost-effective, easily available, low-weight, and environment friendly and have biodegradability properties. The biopolymer-based electrode has a desirable morphology and high surface area and exhibits admirable electrochemical properties. The focus of this report is to highlight (i) the inclusive details of supercapacitors and their types along with strategies to improve their electrochemical performance, (ii) biopolymers and their types used for supercapacitor applications, (iii) various synthesis routes that could be adopted for designing electrode materials based on biopolymers for supercapacitors, and (iv) challenges and future scope of biopolymers as the electrode material in supercapacitor applications. The detailed study here in this report is found to be a topic of interest for the scientific community to fabricate and prepare low-cost, eco-friendly, high electrochemical performance exhibiting electrode materials for supercapacitor applications.
