Seeing is believing: Shedding light on the graphite electrodes of lithium-ion batteries

The electrochemical behavior and morphology evolution of the electrode interface are critical issues for the performance and safety of lithium-ion batteries (LIBs). In this preview, we highlight a shining method in this issue of Matter to visualize the lithium intercalation of the graphite anodes and the state of charge in LIBs using an aggregation-induced emission probe.

First fluorescent probe for graphite anodes of lithium-ion batteryWang et al.MatterJanuary 19, 2023In BriefThis is the first time that AIE fluorescence technology is being used in the characterization of lithium-ion batteries. An AIEgen with catechol moiety is developed as the solid-state fluorescent probe for graphite anodes. This probe displays different responses to the uncharged graphite or the graphite intercalation compound, leading to the visual observation and quantitative measurement of graphite anodes at the same time.
