CONFORMAL SEPARATOR FOR AN ELECTROCHEMICAL CELL COMPRISING A CROSSLINKED POLYMER

摘要

An electrochemical cell is presented having an improved separator disposed at the interfaced of the anode and cathode. In particular, the separator conforms to the contour of the electrode and is thinner than conventional separators made of non-woven fabric. The conformal separator may be formed from combinations of certain polymers and inorganic crosslinking agents. Preferably, the crosslinking agent is a borate or boric acid derivative, and the polymer preferably comprises poly vinyl alcohol.
