A comprehensive review on energy storage materials & technologies: applications of nanofabrication techniques for enhanced performance and efficiency

Abstract Energy storage technologies have become increasingly essential in addressing the global transition toward renewable energy systems. The rapid global shift toward renewable energy has made efficient and reliable energy storage technologies (ESTs) essential for addressing the intermittency of solar, wind, and other clean energy sources. Recent research highlights significant advancements in battery chemistries, supercapacitors, hydrogen storage, and thermal energy systems; however, persistent challenges such as high manufacturing costs, limited cycle life, low energy density, and environmental impacts continue to hinder large-scale implementation. Despite the growing number of studies, there is a lack of integrated knowledge that systematically maps recent trends, material innovations, and application specific challenges. This review aims to bridge that gap by comprehensively analyzing advancements in energy storage technologies over the past decade, evaluating key performance indicators such as energy and power density, efficiency, and lifecycle sustainability. By synthesizing findings from peer-reviewed literatures this study identifies critical barriers and emerging strategies such as nanostructured materials, hybrid systems, and circular economy approaches that could redefine future energy storage landscapes. The conclusions underscore the urgent need for interdisciplinary research, material optimization, and cost-effective designs to accelerate the development and deployment of next-generation storage technologies.
