A method of sealing together conductive parts (4,6) of an electrochemical cell while retaining the said parts (4,6) electrically insulated from each other, which method comprises interposing between the parts to be sealed a sealing material (16) characterised in that the sealing material comprises a thermoplastic bonding material which will flow at the temperature which is to be used for heat-sealing the said parts together and an interlayer of an insulating material having a melting point higher than the said temperature, and in that the parts to be sealed together are heat-sealed by applying heat and pressure to the parts to be sealed thereby to soften the bonding material so that it adheres to the said parts to form the required seal without affecting the insulating material. |
