An electrochemical separator is formed insitu on an electrode surface within an electrochemical cell, preferably an alkaline cell cathode surface. The alkaline cell comprises a zinc anode, a and potassium hydroxide electrolyte. The cathode may comprise a cathode comprising manganese dioxide. The separator may be formed by coating an electrode surface preferably with a low molecular weight copolymer of polyvinyalcohol and polyvinylacetate. The film can be coagulated to form a permeable separator uniformly conforming to and covering the electrode surface irrespective of the shape and contour of the electrode. A separate protector disk can be inserted onto the top surface of the cathode to protect the cathode from shorting in the event that imperfections in the separator surface develop. The protector disk can have a protruding lip which surrounds and protects the inside corner edge of the cathode.
