Analyzing Bending Stresses on Lithium-Ion Battery Cathodes induced by the Assembly Process

The industrialized winding of electrode–separator composites (ESCs; “jelly rolls”) applies bending stress to the winding mandrel. This affects the mechanical integrity of the substrate's coating and adhesion and may reduce the cycle stability and the battery life. Even though this motivates str...
