离子迁移

Electrochemical impedance spectroscopy studies revealed much lower ion mobility in the polyacrylate membrane than in plasticized poly membranes.

电化学阻抗谱研究显示低得多离子迁移的聚丙烯膜比增塑聚膜。

It can be used to explain how these factors affect the transport process of ions.

用此式能很好地解释这些主要因素对离子迁移的影响关系。

It can also result from that the conductance rate of acetylene black and the transfer rate of lithium ion are higher thanthat of graphite.

再就是乙炔黑的电导率和锂离子迁移速度比石墨的也要高。

The pseudo activation energies and the pre-exponent constant (^4) changed with the variation of ion transference number.

表观活化能与指前因子随着离子迁移数t_~+的变化而作相应的变化。

The phosphate-type polymer electrolyte is stable up to 10V and lithium ion transference number increases a little appreciably with the side chain length increases.

体系电化学窗口达到10V，锂离子迁移数随着侧链链长的增加略有增加。

Amount of HACC 25%, the tensile strength of membrane and wet membrane about 0.2% mixed membranes are 53.10, 8.40MPa, water content is 66.4%, IEC 1.97mmol/g, area resistance 2.67Ωcm^2, ion transference number and selective permeability 0.91, 81.6% respectively.

HACC含量为25%，交联度为0.2%的共混膜干强与湿强分别为53.10MPa和8.40MPa，含水量66.4%，IEC为1.97mmol/g，面电阻2.67Ω平方公分，离子迁移数为0.91，选择透过度为81.6%。

High cation transference number is necessary for high performance polymer electrolytes. In this work, hyperbranched lithium polyglycidol sulfate was synthesized as a novel spherical macromolecular lithium salt.

提高锂离子迁移数是聚合物电解质的重要课题，为此本论文以超支化聚合物为母体，合成了一种新型的球状大分子锂盐——超支化聚缩水甘油硫酸锂，并用于微孔型聚合物电解质。

The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.

聚合物结构分析表明：碱性固体聚合物电解质中凝聚态结构以非晶态为主，仅有少量的晶态，结晶度最大为0.1646；添加的各组分与PVA之间都有一定的相互作用，这种作用不仅破坏了聚合物链段的规整性，能够降低聚合物的结晶度，增大无定形区域，提高链段运动的能力，同时这种作用限制K~+离子的运动，提高OH~-的迁移率，从而提高离子电导率；碱性聚合物电解质的离子传导主要发生在无定形区；在本实验测试离子电导率温度范围内，聚合物内部的结构不会发生变化，即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。

The calculated parameter of the drift tube is given subsequently.

利用计算机模拟软件SIMION对离子迁移谱仪进行了模拟实验。

The main factors determined IMS resolutions are the initial ion gate pulse width and diffusion in the drift tube. We conclude the homogeneity of the electric field in the drift tube through analyzing the relation between resolution and ion gate pulse width and drift tube temperature. It is still concluded that inhomogeneity of the electric field has much influence on IMS resolution, which is generally ignored previously.

IMS分辨率最主要的决定因素是离子门脉冲的开门时间和离子在迁移管内的扩散效应，根据在不同离子门开门时间和不同温度下所作的分辨率关系曲线，我们推断出了迁移管内电场的均匀情况，并且得出在一般的IMS工作条件下，迁移管内电场的不均匀对分辨率也有很大的影响，这在以前人们讨论IMS的分辨率时通常被忽略，并没有引起足够的重视。
