Abstract

Fast-charging battery technology plays a vital role in the development of EVs and portable electronics, where quick charging is so crucial in reducing downtime to reduce delays and enhance user friendliness. Though lithium-ion batteries have always been at the top among their peers, their fast-charging capabilities have a limitation connected with thermal management, electrolyte stability, and material degradation. This review discusses recent advances in battery materials for rapid charging, focusing on novel anodes and cathodes like silicon and nickel-rich composition, along with solid-state and gel polymer electrolytes. Emerging trends related to the innovation of solid-state batteries, AI-enabled material development, and hybrid batteries are also discussed, which may provide promising ways to circumvent existing challenges. For the realization of effective, safe, and durable fast-charging solutions, it is always important to balance high charge rates against stability, cost, and sustainability. The scalability of materials and technologies in future research work should be ensured with minimal environmental impact.
