A solid aqueous electrolyte for use in an electrochemical device produced by the process comprising the steps of:
- forming a mixture of an aqueous ionically conductive material, water and a chemically or radiation curable material, said chemically or radiation curable material being capable of crosslinking upon exposure to ionizing radiation or heat;
- and
- subjecting said mixture to ionizing radiation or heat to thereby crosslink said curable material;
- wherein said ionically conductive material is an acid or a neutral salt.
A laminar solid state aqueous electrolyte electrochemical cell comprising:
- an anode layer;
- a cathode layer;
- and
- an aqueous electrolyte layer interposed between said anode layer and said cathode layer;
- said aqueous electrolyte layer being produced by the process comprising the steps of:
- forming a homogeneous mixture of an ionically conductive material, water and a radiation curable material, upon exposure to ionizing radiation or heat;
- and
- subjecting said homogeneous mixture to ionizing radiation or heat to thereby crosslink said curable material;
- wherein said ionically conducive material is an acid or a neutral salt.
A process for producing a solid state laminar electrochemical cell having an aqueous electrolyte comprising the steps of:
- coating an aqueous electrolyte composition comprising an ionically conductive material, water and a radiation curable material onto an anode composition, said radiation curable material being capable of crosslinking upon exposure to ionizing radiation or heat;
- coating a cathode composition onto said electrolyte composition to form a cell assembly;
- and
- subjecting said cell assembly to ionizing radiation or heat to crosslink said curable material of said electrolyte.
