Electrode winding element for non-aqueous electrolyte rechareable battery, non-aqueous electrolyte rechargeable lithium battery including same, method of preparing same
Abstract:
An electrode wound element for a non-aqueous electrolyte rechargeable battery includes a belt-shaped positive electrode; a belt-shaped negative electrode; a belt-shaped porous layer between the belt-shaped positive electrode and the belt-shaped negative electrode; and an adhesive layer formed on the surface of the belt-shaped porous layer, wherein the adhesive layer includes a fluorine resin-containing particulate; a binder supporting the fluorine resin-containing particulate and having a total volume which is that of the fluorine resin-containing particulate; and a heat-resistance filler particle showing a filling ratio of about 40% or greater when being compressed with about 1 MPa.
