Abstract

Abstract : A thianthrene-based small molecule was reported as high-potential cathodes, showing good electrochemical performance with a discharge plateau at 3.9 V ( vs . Li/Li + ), and a discharge capacity of 63 mA h g −1 after 100 cycles at 500 mA g −1 (∼10C). Abstract : Redox-active organic materials have shown great potential as electrodes in lithium-ion batteries (LIBs). However, most of them showed a low discharge potential. We report a thianthrene-based small molecule (BDBDT), which could be facilely synthesized, as a high-potential cathode. The BDBDT cathode exhibited good electrochemical performance with a discharge plateau at 3.9 V ( vs. Li/Li + ) and a discharge capacity of 63 mA h g −1 after 100 cycles at 500 mA g −1 (∼10C). Our results demonstrate that thianthrene-based molecules are promising for the development of high-potential organic electrodes towards rechargeable batteries with high energy and power density.
