摘要
Foils that serve as Li metal anodes suffer from poor cycling and safety concerns due to dramatic volume changes and dendrites formation. In this work, we report a convenient solvent-processed approach to prepare and extract high-purity lithium metal microparticles (Li MPs). As a proof-of-concept, a freestanding porous Li MPs/carbon nanotubes composite anode (LMCA) based on mechanically bound interconnected Li MPs was prepared and showed an improved cycling performance compared to a Li foil anode, as the created 3D porous structures can alleviate electrode volume changes and increase electroactive surface areas.
