A study and discussion on inspection method of electrode defects of the Li-ion power battery

The shortage of energy prompted the Li-ion power battery to become the new alternative energy. As the main body of the Li-ion power battery, the electrode has a great influence on safety, performance, cycle life and capacity of the battery. Thus, it is necessary to inspect surface defects of the electrode precisely. Then, a new inspection method is proposed in this paper. In the method, the machine vision based on smart camera and combined with LabVIEW which is the graphical and virtual programming software is applied to inspect defects of the electrode. This combination of hardware and software is helpful to improve the efficiency of the electrode inspection. © (2013) Trans Tech Publications, Switzerland.
