Abstract
An improved design and manufacturing method is disclosed for calendered, double side segment coated webs. By staggering the leading edges and/or the trailing edges of the segment coatings on one side of the web from those on the other side, web damage, including the incidence of breakage, can be reduced. Further, vibration and wear on the calendering apparatus can be reduced. The invention is particularly useful for heavily calendered webs such as the electrodes in non-aqueous rechargeable lithium ion batteries.
