PREPARATION PROCESS FOR PREVENTING DEFORMATION OF JELLY-ROLL TYPE ELECTRODE ASSEMBLY |
摘要 |
<p>Provided is a method for fabrication of a jelly-roll type electrode assembly having a cathode/separation membrane/anode laminate structure, including: (a) coating both sides of a porous substrate with organic/inorganic composite layers, each of which includes inorganic particles and an organic polymer as a binder, so as to fabricate a composite membrane; and (b) inserting one end of a sheet laminate comprising a cathode sheet and an anode sheet as well as the composite membrane into a mandrel, winding the sheet laminate around the mandrel, and then, removing the mandrel, wherein the organic/inorganic composite layer includes microfine pores capable of moderating a variation in volume during charge/discharge of a secondary battery and an interfacial friction coefficient between the composite membrane and the mandrel is not more than 0.28.</p> |
