Nanospace-Assisted Anti-Oxidative Li Storage on Carbon Nanotubes

摘要

Lithium (Li) metal has attracted significant interest as a next-generation battery anodes due to its high theoretical specific capacity and low redox potential. However, inhomogeneous plating/stripping behavior of Li metal accelerates Li-consuming parasitic reaction and sometimes provokes an internal short circuit problem. In particular, its environmental vulnerability (e.g., notorious reactivity upon exposure to air and water) due to the electrochemical instability poses a formidable challenge to commercial applications, thus it should be resolved as an indispensable prerequisite in addition to resolving the concerns on cell performance and safety.
