This comprehensive review addresses the need for sustainable and efficient energy storage technologies against escalating global demand environmental concerns. It explores innovative utilization of waste materials from oil refineries coal processing industries as precursors carbon-based electrodes in next-generation systems, including batteries supercapacitors. These waste-derived carbon materials, such semi-coke, gasification fine ash, tar pitch, petroleum coke, vacuum residue, offer a promising alternative to conventional electrode materials. They present an optimal balance high content enhanced electrochemical properties while promoting sustainability through effectively repurposing hydrocarbon industries. systematically examines recent advancements fabricating applying electrodes. delves into methodologies converting industrial by-products high-quality electrodes, with particular emphasis on carbonization activation processes tailored enhance performance derived Key findings indicate that higher temperatures may impede development porous structure, using KOH activating agent has proven effective developing mesoporous structures conducive ion transport storage. Moreover, incorporating heteroatom doping (with elements sulfur, potassium, nitrogen) shown promise enhancing surface interactions facilitating diffusion process increased availability active sites, thereby demonstrating potential improved capabilities. The these is evaluated across various configurations electrolytes. Challenges future directions are identified, highlighting deeper understanding microstructural characteristics influence advocating interdisciplinary research achieve precise control over material properties. contributes advancing technology promotes by valuable resources underscores sustainably meeting demands.
