Abstract
Lithium-ion batteries (LIBs) have become a cornerstone technology in the transition toward a sustainable energy future, driven by their critical roles in electric vehicles, portable electronics, renewable energy integration, and grid-scale storage. This review provides a comprehensive examination of the current state of LIB technology, focusing on recent advancements in electrode materials, electrolytes—including solid-state variants—and separator design. The fundamental electrochemical principles underlying LIBs are discussed alongside engineering innovations that enhance performance, safety, and energy efficiency.
Despite their widespread adoption, LIBs face several pressing challenges, such as safety concerns, raw material scarcity, environmental impacts, and end-of-life disposal issues. This review not only explores these limitations, but also presents emerging strategies to address them through next-generation materials, advanced recycling technologies, and sustainable design approaches. Unlike previous studies that narrowly focus on performance improvements, this review emphasizes how existing challenges can be transformed into opportunities for industrial innovation, institutional research, and economic development.
This review offers valuable insights into the future of energy storage by evaluating both the technical and practical aspects of LIB deployment. It presents a forward-looking perspective on the role of LIBs in shaping a cleaner, more resilient, and sustainable energy landscape, serving as a roadmap for continued innovation and responsible technology integration.
