Advancements in the development of nanomaterials for lithium-ion batteries: A scientometric review

Lithium-ion batteries (LIBs) have potential to revolutionize energy storage if technical issues like capacity loss, material stability, safety and cost can be properly resolved. The recent use of nanostructured materials to address limitations of conventional LIB components shows promise in this regard. This review traces research advancements on nanomaterials for LIBs over the past three decades. A comprehensive scientometric analysis of over 100,000 publications reveals exponential growth in nano-LIB research since the 1990s. China and USA lead publications, while the USA dominates nano-LIB patents. In addition to scientific articles, patents are also analyzed in the field of nano-LIB where USA entities lead the filed, granted, and published patents. The technical review examines progress and opportunities for nanostructured anodes, cathodes, electrolytes, separators, and thermal management. Key anode nanomaterials like carbon and silicon aim to boost kinetics and stability. Cathode nanostructures of layered oxides target enhanced rate capability. Nanoparticles in electrolytes and separators improve conductivity and strength. Nanofluids and nanocomposite phase change materials assist thermal regulation. Overall, nanostructures can potentially optimize LIB components, but holistic analysis is needed across all elements. Critical future work should address cost-performance-stability tradeoffs for sustainable nano-LIB commercialization. This review summarizes progress and challenges in nano-LIBs to aid researchers in identifying promising directions.
