Reversible Oxygen-Rich Functional Groups Grafted 3D Honeycomb-Like Carbon Anode for Super-Long Potassium Ion Batteries
文献摘要：
Studies have found that oxygen-rich-containing func-tional groups in carbon-based materials can be used as active sites for the storage performance of K+,but the basic storage mechanism is still unclear.Herein,we construct and optimize 3D honeycomb-like carbon grafted with plentiful COOH/C=O functional groups(OFGC)as anodes for potassium ion batteries.The OFGC electrode with steady structure and rich functional groups can effectively contribute to the capacity enhancement and the formation of stable solid elec-trolyte interphase(SEI)film,achieving a high reversible capacity of 230 mAh g-1 at 3000 mA g-1 after 10,000 cycles(almost no capacity decay)and an ultra-long cycle time over 18 months at 100 mA g-1.The study results revealed the reversible storage mechanism between K+and COOH/C=O functional groups by forming C-O-K compounds.Meanwhile,the in situ electrochemical impedance spectroscopy proved the highly reversible and rapid de/intercalation kinetics of K+in the OFGC electrode,and the growth process of SEI films.In particular,the full cells assembled by Prussian blue cathode exhibit a high energy density of 113 Wh kg-1 after 800 cycles(calculated by the total mass of anode and cathode),and get the light-emitting diodes lamp and ear thermometer running.
