This book is a comprehensive exploration of the synergy between green chemistry principles and electrochemical energy storage (EES) technologies and the importance of this relationship. It provides an in-depth analysis of mega-trends in the renewable energy industry and the imperative for advanced EES solutions with a particular focus on sustainable solutions for lithium-ion batteries (LIBs).Early chapters detail the material chemistry of LIBs and recent innovations in their components including anodes, cathodes, electrolytes and separators. Extending beyond LIBs, the book explores various alternative EES technologies including non-lithium mono- and multivalent-ion batteries, metal-air batteries, fuel cells, Li-S batteries, supercapacitors and sodium-ion batteries. Novel EES technologies are analyzed, with an eye to their associated challenges such as device utilization and recycling. The book concludes with a summary of future prospects and how we might overcome obstacles to implementing sustainable EES solutions, offering readers a nuanced perspective on the pivotal role of green chemistry in shaping the trajectory of next-generation electrochemical energy storage within the evolving renewable energy landscape.
