The invention relates to a process for manufacturing a gelled polymer electrolyte (GPE), comprising the steps of:
- solubilizing a polymer in a solvent, leading to the formation of a first homogeneous solution;
- mixing said solution with an electrolyte consisting of aluminum chloride with a predetermined weight ratio of electrolyte to polymer;
- mixing said mixture until a second homogeneous solution is obtained;- pouring said second homogeneous solution onto a substrate;
- removing/evaporating the solvent to obtain a homogeneous GPE membrane: polymer;- mixing said mixture until a second homogeneous solution is obtained;
- pouring said second homogeneous solution onto a substrate;
- removing/evaporating the solvent to obtain a homogeneous, mechanically stable GPE membrane;
- activating the polymer membrane, to further etch/deposit aluminum on the GPE membrane.
