Methods Cyclohexane, ethyl acetate and glacial acetic acid (8∶8∶0.8) were used as the developing solvent. Samples were analyzed on a layer plate of silica gel G thin by using 20% phosphomolybdic acid as chromogenic agent.

以环己烷乙酸乙酯冰醋酸（体积比8∶8∶0.8）为展开剂，以羧甲基纤维素钠为黏合剂自制硅胶G薄层板，20％磷钼酸溶液为显色剂，进行薄层色谱分析。

In order to improve the electrochemical performance of LiCoO2, the majorities of researchers are working on the adjustment and substitution of the lay element, in order to increase the extract and deintercalated quantity and overcharge-resistant ability, the method pillaring in the interbed is brought forward for strengthening the structure stability.

目前为了改善LiCoO2的电化学性能，多数研究者进行的是层板元素的调控和替换，但实际效果仍不甚理想，我们采取层间柱撑金属离子的办法来提高材料的结构稳定性，以增加LiCoO2材料的锂离子可脱嵌量以及耐过充电压。

There are TAIHONG 2LPSE0503MW-250 single unadhesive ED flexible copper coated lamination and Nippon Steel CIPW-25080 single ED FCCL.Regards to photoresists, Dupont FX915 dry film would be the best choice for the production of COF FPC after the comparison in photosensitive property, resolution, adhesiveness and operating procedure between the different resist thicknesses of Dupont FX900 series.

光致抗蚀剂方面：通过对比杜邦FX900系列两种不同抗蚀层厚度干膜(FX930与FX915)的感光性能、分辨率、附着力、操作工艺等，确定出杜邦FX915(抗蚀层厚度15μm)为更适用于COF挠性印制板制作的干膜；并对干膜的曝光参数进行了优化，最佳曝光级数5级(相对于21级曝光尺)，曝光能量片式150mJ/cm~2、卷式110mJ/cm~2，使其更加适合于精细线路的制作。
