Electrolyte formulation with high stability towards both Li metal anode and high-voltage cathode is considered as one of key points for the high-energy density lithium metal batteries(LMBs).In our previous study,by adding only 2%of 2-fluoropyridine(2-FP)as the additive in the carbonate and ether-based electrolyte formulations effectively suppressed Li dendrite *** this study,we further found that the main fluoropyridine(FP)family members can serve as not only the effective additive but also the excellent electrolyte solvent in the electrolyte formulations to enhance the performance of *** the 2-FP,when it was also used the electrolyte solvent and paired with single-salt lithium bis(trifluoromethylsulfonyl)imide(Li TFSI),the obtained electrolyte formulation of 1 M Li TFSI in pure2-FP solvent not only allowed faster ion transport though solvation effect,but also possessed impressive oxidation stability window over 4.3 *** a result,the high-voltage LiNi_(1/3)Mn1_(/3)Co_(1/3)O_(2)(1.5 mA h cm^(-2))|Li metal battery with it exhibited a capacity retention of more than 80%over a long-term cycle even at 0.45 m A cm^(-2)with a lean electrolyte(30μL).Meanwhile,for another FP family member(i.e.,3-FP)as the electrolyte additive,the 4.3 V LMBs with the carbonate-based electrolyte containing only 1%of 3-FP maintained 83.9%of initial capacity after 200 cycles at 0.75 m A cm^(-2).Density functional theory(DFT)calculations and experiments confirmed that three typical FPs,i.e.,2-FP,3-FP and 4-FP can not only regulate the initial Li nucleation process,but more importantly also induce a protective layer,leading to a uniform and dendrites-free Li *** bifunction of the FP family member as either electrolyte solvent or additive in the electrolyte formulations should be promising for the achieving of dendrites-free high-energy density LMBs.

作者： zhengkun xie Gaiping Li Baoxian Ye College of Chemistry and Molecular Engineering Zhengzhou University

The chrysin and baicalein are the major flavonoids found in Oroxylum indicum, an essential herb in traditional Chinese medicine for thousands of years. Owing to the similar characteristics and physiochemical property of chrysin and baicalein, the highly sensitive simultaneous electrochemical determination of chrysin and baicalein is a great challenge. In this work, a novel, simple and highly sensitive electrochemical method was proposed using a TaO nanoparticles and antiseptic chitosan modified carbon paste electrode(TaO-CTS-CPE). Scanning electron microscope(SEM), X-ray diffraction spectroscopy(XRD), Fourier transform infrared spectroscopy(FTIR), cyclic voltammetry(CV) and electrochemical impedance spectrum(EIS) were used to characterize the sensor and investigate the electrochemical response of the sensor. Under the optimum conditions, the electrochemical sensor exhibited excellent electrocatalytic activity toward the oxidation of chrysin and baicalein. The results demonstrated that the highly sensitive and simultaneous determination of chrysin and baicalein was successfully achieved and the modified electrode had a linear response range of 0.08.0 μM for both chrysin and baicalein, and the detection limits of chrysin and baicalein obtained were 0.03 and 0.05 μM(S/N=3), respectively. Furthermore, the proposed sensor displayed high sensitivity, excellent stability and satisfactory results in Oroxylum indicum samples analysis.

对大同煤田5^(#)煤层煤样进行采集,并进行高压容量法等温实验,发现吸附量与压力和温度在高压状态下符合朗格缪尔方程,利用最小二乘法求出吸附常数a值、b值。综合分析实验数据得出:吸附罐内的绝对瓦斯压力值越高,煤样的吸附量越高,当绝对瓦斯压力值达到一定压力以后,煤样吸附瓦斯量逐步趋于饱和并在4.5~5.0MPa之间实现动态平衡;测出了5^(#)煤层煤样的吸附常数值,发现煤样放置时间变长,煤的挥发分和灰分也随之增加;煤样吸附瓦斯规律先是吸附速率急剧变快,然后趋于平缓,最后实现动态平衡。
