Abstract:
1. A method for manufacturing a cathode for an electrolysis cell coated with a separator comprising ceramic material particles embedded in a sintered network of organic polymer fibres, the ceramic material particles comprising zirconium chemically bound to hydroxyl groups, the method comprising the following sequential steps: forming a suspension of organic polymer fibres incorporating mechanically bound zirconium oxide; depositing the suspended fibres on a foraminous metal substrate; executing a thermal treatment at a temperature sufficient for sintering the polymer fibres in a porous reticular structure; soaking of the separator in a hydrating solution at a temperature comprised between about 0° C. and about 100° C. under a negative pressure for a period of at least 30 minutes; and forming the separator comprising ceramic material particles embedded in the sintered network of organic polymer fibres, the ceramic material particles comprising zirconium chemically bound to hydroxyl groups.
