description: Byline: Yujia Liang, Chao Luo, Fei Wang, Singyuk Hou, Sz-Chian Liou, Tingting Qing, Qin Li, Jing Zheng, Chunyu Cui,Chunsheng Wang Keywords: azo compounds; conjugated structure; EELS; high temperature; potassium-ion batteries Abstract The wide applications of rechargeable batteries require state-of-the-art batteries that are sustainable (abundant resource), tolerant to high-temperature operations, and excellent in delivering high capacity and long-term cycling life. Due to the scarcity and uneven distribution of lithium, it is urgent to develop alternative rechargeable batteries. Herein, an organic compound, azobenzene-4,4'-dicarboxylic acid potassium salts (ADAPTS) is developed, with an azo group as the redox center for high performance potassium-ion batteries (KIBs). The extended I-conjugated structure in ADAPTS and surface reactions between ADAPTS and K-ions enable the stable charge/discharge of K-ion batteries even at high temperatures up to 60 [degrees]C. When operated at 50 [degrees]C, ADAPTS anode delivers a reversible capacity of 109 mAh g.sup.-1 at 1C for 400 cycles. A reversible capacity of 77 mAh g.sup.-1 is retained at 2C for 1000 cycles. At 60 [degrees]C, the ADAPTS-based KIBs deliver a high capacity of 113 mAh g.sup.-1 with 81% capacity retention at 2C after 80 cycles. The exceptional electrochemical performance demonstrates that ADAPTS is a promising electrode material for high-temperature KIBs. CAPTION(S): Supplementary Supplementary Supplementary
