An electrochemical cell is made by assembling an anodic layer and a cathodic layer, these layers being separated by a plasticised membrane of polymeric material consisting of a PVdF-type polymer chain, and ethylene carbonate as a plasticiser, but containing no lithium salt, the membrane being less than 30 mum thick and being cast from a volatile solvent. The resulting cell precursor is soaked in an electrolyte solution to form the cell. The membrane absorbs the electrolyte solution, forming a gelled or polymeric electrolyte. |
