Porous organic cages(POCs)with permanent porosity and excellent host–guest property hold great potentials in regulating ion transport behavior,yet their feasibility as solid-state electrolytes has never been testified in a practical ***,we design and fabricate a quasi-solid-state electrolyte(QSSE)based on a POC to enable the stable operation of Li-metal batteries(LMBs).Benefiting from the ordered channels and cavity-induced anion-trapping effect of POC,the resulting POC-based QSSE exhibits a high Li+transference number of 0.67 and a high ionic conductivity of 1.25×10^(−4) S cm^(−1) with a low activation energy of 0.17 *** allow for homogeneous Li deposition and highly reversible Li plating/stripping for over 2000 *** a proof of concept,the LMB assembled with POC-based QSSE demonstrates extremely stable cycling performance with 85%capacity retention after 1000 ***,our work demonstrates the practical applicability of POC as SSEs for LMBs and could be extended to other energy-storage systems,such as Na and K batteries.

采用水热法制备了磷酸化黍糠基生物炭负载δ-MnO_(2)(PBC@δ-MnO_(2))纳米复合催化剂,利用SEM对催化剂进行表征,研究了其活化过二硫酸盐(PDS)降解孔雀石绿(MG)的效果及其去除机理。考察了初始pH、PDS浓度、PBC@δ-MnO_(2)投加量等反应条件对MG去除的影响。分析PBC@δ-MnO_(2)/PDS体系中的主要活性物质,推测该反应体系中可能的反应机制。结果表明,在PBC@δ-MnO_(2)/PDS体系中,随着初始pH、PDS浓度、PBC@δ-MnO_(2)投加量的升高,MG去除率也逐渐增大,当PBC@δ-MnO_(2)投加量为0.2 g/L,PDS浓度为0.5 mmol/L,初始pH为5时,MG的去除率可达到92.61%。自由基猝灭试验和EPR分析表明,单线态氧(^(1)O_(2))是PBC@δ-MnO_(2)/PDS体系中的主要活性物种,对MG的去除起主导作用。

Interval prediction of wind power,which features the upper and lower limits of wind power at a given confidence level,plays a significant role in accurate prediction and stability of the power grid integrated with wind ***,the conventional methods of interval prediction are commonly based on a hypothetic probability distribution function,which neglects the correlations among various variables,leading to the decrease of prediction ***,we improve the multi-objective interval prediction based on the conditional copula function,through which we can fully utilize the correlations among variables to improve prediction accuracy without an assumed probability distribution *** use the multi-objective optimization method of nondominated sorting genetic algorithm-II(NSGA-II)to obtain the optimal solution *** particular best solution is weighted by the prediction interval average width(PIAW)and prediction interval coverage probability(PICP)to pick the optimized solution in practical ***,we apply the proposed method to three wind power plants in different cities in China as examples forvalidation and obtain higher prediction accuracy compared with other methods,i.e.,relevance vector machine(RVM),artificial neural network(ANN),and particle swarm optimization kernel extreme learning machine(PSO-KELM).These results demonstrate the superiority and practicability of this method in interval prediction of wind power.

The phase diagram of the CsBr-CaBr2 system was re-determined by using differential thermal analysis and high ternperature and room ternperature X-ray diffraction analysis. It is concluded that there are three intermediate compounds in this system： *** melting compound, CsCaBr3, with a melting point of 823℃ and two incongruently melting compounds, Cs2CaBr4 and Cs3Ca2Br7, whose peritectic points being 597℃ and 635℃, respectively. X-ray diffraction analysis indicated that compound CsCaBr3 is of slightly distorted perovskite structure.
