The integration of energy storage capabilities has revolutionized the advanced textile industry. This chapter explores the application of nanoparticles (NPs) in textiles to create energy-storage fabrics with vast potential in wearable technology, smart clothing, and other textile-based applications. This has been clarified by integrating various NPs for energy storage capabilities like metal oxides, carbon-based NPs, and conducting polymers. Owing to the unique electro-mechanic properties of NPs, these are potential candidates for textiles with no compromise on the inherent properties of fabric. This study delves into various synthesis strategies for NPs integration into textiles, highlighting the advantages and challenges in the integration process. The functionalization and fabrication techniques to induce improved energy storage capabilities are highlighted. Wearable electronics, such as smartwatches and health monitoring devices, can benefit from textiles with integrated energy storage, allowing for longer battery life and reduced bulkiness. Safety and environmental concerns associated with the utilization of NPs in textiles are also discussed. Besides, the impact of NPs leaching on human health and the environment is part of the discussion. This chapter comprehensively addresses the NPs infused energy storage textiles along with the challenges and opportunities available to researchers and industry professionals while envisaging future developments that could further revolutionize this dynamic field.
