Popis: | 105 Lithium battery has been widely used in industry and 3C commercial devices owning to its remarkable properties such as high energy, high power efficiency, long cycle life, no memory effect, low electrical self-discharge, and good to the environment. In addition, lithium ionic battery research has been recently attracted to great attention in renewable energy techniques to energy crisis and environmental issues. Among the relative studies, separator acted as a key material of the lithium battery is also drawn great concern. In this study, Causes & Effects Chart was applied to find out the key factors that affecting the quality characteristics of the gurley and the thickness of the membrane which are the in the middle process of separator manufacture. Moreover, Central Composite Design (CCD), one method of Response Surface Methodology (RSM), was employed to optimize the process parameters in order to improve the production yield and lower the cost. The results showed that the average of membrane gurley (in second) is improved from 10.8s to 9.27s where its target is 9s, and its standard deviation is reduced from 0.66s to 0.56s. The average of membrane thickness (in μm) is improved from 20.43μm to 20.02μm with the target of 20μm, and its standard deviation is also shrank from 0.18μm to 0.12μm. |
