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 infl ation occurs. If these cells that are susceptible to failure pass through to the end user, the results could be catastrophic. This paper describes how to mitigate these occurances in the dry cell stage.
