Claim 8:
9. A method according to claim 1, wherein the method comprises mixing solvent with PVDF and surfactant at a volume concentration in the range of 0.1% to 10% relatively to the solvent volume to obtain the adhesive, wherein the solvent comprises more than 50% dimethyl acetamide and the surfactant comprises more than 50% octyl phenol ethoxylate; after the mixing applying the adhesive to the surface; after application of the adhesive to the surface, adding water to the adhesive and causing precipitation of PVDF by the addition of water; awaiting evaporation of the solvent at room temperature and then bonding the plates to each other by hot-pressing the plates together with a pressure in the range of 1 kPa to 10 kPa and at a temperature above the melting temperature of the PVDF and then reducing the temperature while still pressing until the temperature is below the crystallization temperature of the PVDF.
