A dendrite-suppressed Li composite anode decorated by lithiophilic Li-Pb alloys for stable Li metal batteries

Abstract

A lithium-rich lithium-lead alloy-based composite electrode, featuring Li22Pb5 microparticles dispersed in lithium metal, is fabricated by mechanical rolling to suppress lithium dendrite growth. The lithiophilic Li-Pb alloys can guide a uniform lithium plating process, resulting in impressive cycling stability of both symmetric and full cells.
