Abstract

Provided herein a method of preparing electrode assemblies for lithium-ion batteries. The method disclosed herein comprises a step of pre-drying separator in the battery manufacturing process before the stacking step, thereby significantly lowering the water content of the separator. Therefore, separators can be used to prepare electrode assemblies regardless of conditions under which they are stored or transported. In addition, the peeling strength between the porous base material and protective porous layer is largely unaffected by the drying process disclosed herein.
