1Cyclic-anion salt for high-voltage stable potassium-metal batteries显示文摘Electrolyte anions are critical for achieving high-voltage stable potassium-metal batteries(PMBs).However,the common anions cannot simultaneously prevent the formation of‘dead K’and the corrosion of Al current collector,resulting in poor cycling stability.Here,we demonstrate cyclic anion of hexafluoropropane-1,3-disulfonimide-based electrolytes that can mitigate the‘dead K’and remarkably enhance the high-voltage stability of PMBs.Particularly,even using low salt concentration(0.8 M)and additive-free carbonate-based electrolytes,the PMBs with a high-voltage polyanion cathode(4.4 V)also exhibit excellent cycling stability of 200 cycles with a good capacity retention of 83%.This noticeable electrochemical performance is due to the highly efficient passivation ability of the cyclic anions on both anode and cathode surfaces.This cyclic-anion-based electrolyte design strategy is also suitable for lithium and sodium-metal battery technologies.Yanyao Hu Ling Fan Apparao M.Rao Weijian Yu Caixiang Zhuoma Yanhong Feng Zhihui Qin Jiang Zhou Bingan Lu 2022National Science Review2022,9,10:1

3Formation of coke in thermal cracking of jet fuel under supercritical conditions显示文摘Continuous-flow reactor experiments were carried out to study coke formation from thermal crack-ing of home-made jet fuel RP-3 under supercritical con-ditions.The mechanism and precursor of coke forming were analyzed.The starting cracking temperature of RP-3 fuel was determined to be 471.8uC by differential scan-ning calorimetry(DSC).Temperature-programmed oxidation and scanning electron microscopy(SEM)characterizations of the stressed tubes showed that there are three different coke species including chemisorbed carbon,amorphous carbon and filamentous coke in the solid deposits.More than 90%of coke deposits are carried away by the supercritical fluid,which has strong capabilities of extraction for coke deposits and their pre-cursors.There were 17.1 wt-%of iron and 11.1 wt-%of chromium found on the coke surface detected by energy dispersive spectroscopy(EDS)which suggests carbure-tion on alloy.RP-3 fuel and its cracking liquids were analyzed by GC-MS,which showed that the content of alkyl benzene and alkyl naphthalene increased evidently in cracking liquids.Yuhong ZHU Caixiang YU Zimu LI Zhentao MI Xiangwen ZHANG 2008Frontiers of Chemical Science and Engineering2008,2,1:0
