Abstract

Stable lithium (Li) metal anodes are highly pursued for advanced energy-storage devices with superior energy density. However, drawbacks such as the growth of Li dendrites and significant volume fluctuations during cycling, both of which cause safety hazards and limit battery life spans, have impeded the practical application of Li metal anodes. Advanced carbon nanostructure frameworks are emerging as an attractive strategy to suppress Li dendrites and relieve volume fluctuations by regulating the behaviors of Li plating/stripping, leading to lightweight and binder-free electrodes. From this perspective, this chapter focuses on the recent progress of innovative nanocarbon-based frameworks for Li anodes employing carbon interlayers and nanostructured host materials. The influences and advantages of these approaches are discussed in detail. Finally, we discuss the challenges and promising directions for the future development of carbon-based Li anodes in relevant applications.
