Year: 2024
Type: article
Abstract: To investigate the effect of mono-halogenation on the performance of anthraquinone cathode in lithium-ion batteries, the structures and electrochemical properties of AQ derivatives functionalized with single chlorine and bromine were studied. The microstructure and morphology were characterized by XRD and SEM, and the electrochemical properties were conducted using galvanostatic charge/discharge, cyclic voltammetry and electrochemical impedance spectroscopy. 1-BrAQ, 2-BrAQ, and 2-ClAQ showed improved cyclic stability and higher platform voltage than the AQ cathode, and the capacity retention rates of 2-ClAQ and 2-BrAQ after 50 discharge cycles are 64.6% and 77.8%, respectively, which are twice the capacity retention rate of the AQ positive electrode under the same conditions.
