Advancements in additive manufacturing for electrochemical energy storage devices

Abstract

This study explores the application of additive manufacturing (AM) techniques in enhancing electrochemical energy storage devices (EESDs), focusing on improvements in efficiency, scalability, and structural stability. As demand for portable and sustainable energy solutions grows, particularly in consumer electronics and electric vehicles, AM’s capacity to create complex, customizable designs become invaluable. Key AM techniques covered unique advantages such as low-cost production, multi-material capabilities, and efficient prototyping. Central to this research is the customization of electrode materials for optimal ion and electron transport, with a focus on 3D electrode designs that enhance charge transfer and stability. Carbonaceous and non-carbonaceous materials are examined for their role in providing the necessary conductivity and structural integrity for EESDs, with particular attention to innovative carbon-based materials like graphene foams, which have shown significant promise in lithium-ion battery applications. Additionally, the study highlights the potential for AM to create structural EESDs—energy storage solutions that serve as integral parts of a device’s architecture—thereby advancing compact and flexible storage systems suited to modern energy demands. While AM’s impact on EESD development is substantial, challenges such as optimizing material synthesis, adjusting electrode geometries, and reducing costs remain critical areas for further research. Ultimately, this work demonstrates AM’s transformative role in advancing energy storage technology, underlining the need for continued innovation to fully harness AM’s potential in creating efficient, sustainable, and high-performance EESDs. This study provides a foundation for future exploration into AM-enabled EESDs, supporting the broader goal of sustainable energy advancement across multiple industries.
