Assessment of battery cell assembly through non-invasive cell characterization using X-ray computer tomography: Presented at EVS 31 EVTeC 2018, Kobe, Japan, October 1 - 3, 2018

摘要

The quality of lithium-ion battery electrodes can be characterized by manifold different analytical methods. The manufacturing of the lithium-ion battery cell, especially the assembly of the electrode-separator-composite, lacks this high variety of analytical methods. All the more, it is of great importance to characterize the ESC of the cell, due to possible manufacturing failures which lead later to consequences in the usage phase of the battery cell. In this paper, a method is presented and evaluated for an assessment of lithium-ion battery cells ESC assembly through non-invasive x-ray computer tomography imaging and automated image analysis.
