Manufacture of flexible thin layer electrochemical cell

Abstract

A flexible thin layer electrochemical cell and a method of using a lamination process for manufacture thereof, the cell having a plurality of layers including a first electrode layer and a second electrode layer with a separator interspersed therebetween and wherein the separator serves as a lead element upon which the other layers are laminated using an adhesive frame mounted on the lead element.

What is claimed is:  
     
         1 . A separator layer for use in the production of a flexible thin layer electrochemical cell, said separator layer comprising an impregnator applied thereto, which impregnator is susceptible to impregnate said separator layer during lamination processing applied to said layer to form said cell.  
     
     
         2 . A separator layer according to  claim 1 , wherein said impregnator comprises an adhesive material.  
     
     
         3 . A separator layer according to  claim 2 , wherein said adhesive material is selected from the group consisting of a hot melt material, a hot melt pressure sensitive material and a UV curable pressure sensitive material.  
     
     
         4 . A separator layer according to  claim 1 , wherein said impregnator comprises an impregnation agent operable to cause impregnation into at least one of said layers of at least one material of said impregnator.  
     
     
         5 . A separator layer according to  claim 1 , wherein said impregnator is operable to restrict electrical conductivity in a region of any electrically conductive layer into which it is absorbed.  
     
     
         6 . A separator layer according to  claim 4 , wherein said impregnation agent is selected from the group consisting of polyisobutylene, ethyl cellulose, a fluoro polymer, an acrylic resin, a vinyl resin, and polyurethane.  
     
     
         7 . A separator layer according to  claim 1 , having a first side and a second side and having said impregnator applied on both of said first side and said second side for lamination thereto of further layers to form said cell.  
     
     
         8 . A separator layer according to  claim 7 , having a positive electrode layer laminated to said first side and a negative electrode layer laminated to said second side, each electrode layer further comprising electrolyte.
