Modeling and Optimization of a Jackfruit Seed‐Based Supercapacitor Electrode Using Machine Learning

Abstract

Supercapacitors can be used for portable energy storage applications. In this study, machine learning techniques are applied to optimize the process of preparation of supercapacitor electrodes from chemically activated carbon made from jackfruit seeds. Experimental trials were carried out using statistical design of experiments. Artificial neural network was employed to generate the process model and a multiobjective optimization was attempted by means of swarm intelligence and the Derringer's desirability function. The optimized electrode demonstrated high capacitance and low resistance making it suitable for supercapacitors. The algorithm developed in the study can be adopted by process engineers for efficient optimization.

Machine learning-assisted materials development and device management in batteries and supercapacitors: performance comparison and challenges

“…In an optimization problem, Mathew et al performed particle swarm optimization from an ANN regression model to identify the optimal process parameters based on the resulting specific capacitance and equivalent series resistance of an activated carbon supercapacitor. 158 The model achieved an R 2 of 0.998 and 0.979 for predicting specific capacitance and equivalent series resistance, respectively. However, the optimized synthesis parameters demonstrated no improvement over the highest-performing supercapacitor generated during the experimental trials.…”
