Assink, R A; Arnold, C Jr

Homogeneous and radiatively grafted membranes were evaluated as separators for the zinc/ferricyanide storage battery. An accelerated aging test demonstrated that membrane failures could be attributed to both mechanical and chemical mechanisms. A series of radiation grafted membranes using fluorinated film substrates were prepared by RAI Research Corporation. One of these membranes has exhibited a 79.3% average energy efficiency for over 700 charge/discharge cycles in a test cell.
