Protection of lithium-dendrite growth by functionalized carbon nanodot additives

摘要

The present invention relates to a technology for inhibiting growth of lithium dendrite using functionalized carbon nanodots, and functionalized carbon nanodots as an additive for improving the lithium plating type and cycling stability of a lithium metal battery. CDs) to present a new design. Various functional groups of functionalized carbon nanopoints provide strong lithium ion affinity and enable uniform lithium ion transfer to the current collector, thereby reducing dendrite-free metals during the plating/stripping process. ) Can be enabled.
