How To Decrease Risks Of Catastrophic Failures In EV Battery Cells: It Is Not What You Think

Lithium-ion battery technology has played a big role in the advancement and user experience of electric vehicles and other consumer electronic products. As market competition intensifies, manufacturers are striving to achieve higher power densities and production throughput. While lithium-ion technology has matured, electrical shorts can still develop inside the cell after passing production tests due to burrs or particles on the positive electrode reaching the negative electrode after inflation occurs. If these cells, which are susceptible to failure, reach the end user, the results could be catastrophic.

In order to decrease the risk of failure in the field, the root cause must be identified and any defective cells must be filtered out before they reach the end user. You may be surprised to learn that traditional Hipot and IR tests fail to catch future failures. So how do you properly identify the root cause which makes a cell susceptible to a greater risk of failure?

Join this session to learn how to identify and mitigate these occurrences in the dry cell stage before electrolytes are introduced.
