Characterisation of Lithium Ion Battery cells using EIS techniques

该项目将需要EIS与以下内容的相关性：-1)正常群体中电池的时域电气性能过程数据，以及在制造的最后阶段中出现表面缺陷的电池的时域电气性能过程数据；2)分布的上下四分位数中电池的耐久性生命周期性能。NU和NMUK参与了APC项目HEDB(2016-1018)，在该项目中，他们合作安装了一个原型测试站，该测试站可以对产品样品进行自动化电化学阻抗谱（EIS）测量，也可以在手动配置中使用手动进料进行相同的测量。这些测量目前不构成生产线上自动化QA过程的任何部分。预计这种测量技术可以集成到未来的生产设施中，以增加收集到的数据。

The project will require EIS correlation with the following:-1) Time domain electrical performance process data of cells in the normal population and those rejected at the final stage of manufacturing that exhibit surface imperfections2) Durability life cycle performance of cells in the upper and lower quartiles of the distribution.NU & NMUK were involved in APC project HEDB (2016-1018) within which they collaborated to install a prototype test station which makes automated Electrochemical Impedance Spectroscopy (EIS) measurements on samples of product or can be used in manual configuration to make the same measurements with manual feed. These measurements do not currently form any part of the automated QA process on the production line. It is expected this measurement technique could be integrated into future production facilities to augment the data gathered.
