Lithium metal anode is a promising electrode with high theoretical specific capacity and low electrode ***,its unstable interface and low Coulombic efficiency,resulting from the dendritic growth of lithium,limits its commercial ***-1(PIM:polymer of intrinsic microporosity),which is a polymer with abundant micropores,exhibits high rigidity and flexibility with contorted spirocenters in the backbone,and is an ideal candidate for artificial solid electrolyte interphases(SEI).In this work,a PIM-1 membrane was synthesized and fabricated as a protective membrane on the surface of an electrode to facilitate the uniform flux of Li ions and act as a stable interface for the lithium plating/stripping ***-like lithium with rounded edges was observed under the PIM-1 *** Li@PIM-1 electrode delivered a high average Coulombic efficiency(99.7%),excellent cyclability(80%capacity retention rate after 600 cycles at 1 C),and superior rate capability(125.3 m Ah g-1 at 10 C).Electrochemical impedance spectrum(EIS)showed that the PIM-1 membrane could lower the diffusion rate of Li+significantly and change the rate-determining step from charge transfer to Li+***,the PIM-1 membrane is proven to act as an artificial SEI to facilitate uniform and stable deposition of lithium,in favor of obtaining a compact and dense Li-plating *** work extends the application of PIMs in the field of lithium batteries and provides ideas for the construction of artificial SEI.

本文利用北京地区的北京台(BJI)和北京十三陵台(BMT)的地磁场X、Y和Z分量时均值数据,研究了1960年至2013年期间该地区地磁场Sq强度的季节变化和长期变化.结果表明:(1)BJI台和BMT台的地磁场Sq不仅变幅相近,而且具有一致的地方时变化、季节变化、太阳活动周变化和长期变化.(2)BJI台和BMT台Sq强度的逐月变化,其中ASq(X)主要表现为春秋增强而冬夏减弱的季节变化.ASq(Y)呈现出夏季增强的半年变化.ASq(Z)变化较为复杂.虽然在5月和9月出现减小,但是总体来看,其变化曲线也具有夏季增强的半年变化特征.同时,Sq强度与太阳活动F107指数之间存在明显的正相关关系,具有一致的11年太阳活动周变化和长期变化,反映出了Sq与太阳活动之间的密切关系.(3)BJI台和BMT台Sq强度差值dASq表明,在大多数年份,两个台站的Sq强度之差一般不超过±2nT,同时没有明显的季节或年周期变化特征.在2000年和2001年太阳活动高年,dASq出现显著增强,最大可达12.3nT.反映出了北京地区Sq场强度梯度的剧烈扰动与太阳活动之间的密切关系,意味着在太阳活动高年,Sq电离层发电机电流的局部结构可能发生了明显的改变.
