<p>A separator for an electrochemical cell and a method of assembling an electrochemical cell are provided. The separator (24) includes a porous paper substrate impregnated and/or coated with a polymer solution (66) that coagulates to prevent electrical shorting while allowing ion permeation. The method include the steps of providing a container (12) having a bottom end and a top end and upstanding walls disposed therebetween, disposing positive electrode and negative electrodes in the container, providing a sheet of porous paper substrate, forming the sheet of porous substrate into a separator, applying alkaline solution to the separator, applying a liquid polymer material to the porous substrate in the presence of the alkaline solution so that the polymer solution coagulates to form a semi-solid material, and disposing the separator between the positive electrode and the negative electrode.</p> |
