| Summary: | 碩士 === 國立屏東科技大學 === 材料工程研究所 === 106 === In recent years, there has been a growing demand for batteries for power supply due to the booming development of portable electronic products and electric transport equipment. , Lithium secondary battery which has the advantages of high energy, high power, light weight, long life and good environmental protection, is currently the best mobile power supply. The key issue of lithium battery technology lies in the safety of lithium batteries, but also the highest proportion of the cost component is the separator. The main function of the separator is when the battery abnormal temperature rises, the battery can stop the charge-discharge reaction to avoid the battery explosion caused by overheating.
In this dissertation, the coating method was used to coat different BX-100, BX-500 and BX-900 solutions on different substrates. After heat treatment at different temperatures, surface structure analysis and characterization were carried out as the evaluation of a separator. And then, the above-mentioned separators, using button-type lithium battery assembly, assembled into a button-type lithium battery to measure its electrical properties.
The results show that BX-100, BX-500 and BX-900 solution after heat treatment at different temperatures have different ability of pores filling, which will affect the performance of button-type lithium battery.
