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.

Abstract
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.File in questo prodotto:
