X-ray computed tomography is a 3D imaging technique that is able to provide information about both inner and outer parts of battery cells without their destruction. We will present this technique allowing us access to the batteries data in the whole range of scales – from the analysis of entire cells down to microstructure of electrodes. We will focus on the changes in the structure during the battery's aging process and the manufacturing defects.
Accurate and efficient screening of retired lithium-ion batteries from electric vehicles is crucial to guarantee reliable secondary applications such as in energy storage, electric bicycles, and smart grids.
It is difficult to use conventional capacity detection methods to determine nondestructively and rapidly the capacity of lithium-ion (Li-ion) batteries used in electric vehicles.
