Battery Fire – Decreasing Risk of Electrical Shorts in Lithium Ion Battery Cells

On rare occasions, an electrical short can 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 that are susceptible to failure pass through to the end user, battery fire or explosion could be a catastrophic result. This paper describes how to mitigate these occurrences in the dry cell stage. ...
