Abstract

1471279 Metal-air batteries LUCAS BATTERIES Ltd 8 Aug 1974 [10 Aug 1973] 37918/73 Heading H1B A metal-air battery comprises a casing 6, a plurality of cells within the casing, each cell including an air cathode and a metal anode insulated from the cathode and with a space therebetween, and a filling channel 8 defined by the casing 6, each cell having a solid pellet of electrolyte solute in the space therewith and the battery being arranged to be activated by the introduction of the electrolytic solvent into the channel which channel communicates with the space in each cell by way of a filling aperture 9 and a venting aperture 10 in the casing, a cover 5 partly covering the channel and arranged so that when the liquid is placed in the channel the battery may be tilted to a position in which the venting apertures 10 are above the liquid surface to allow air to escape as it is displaced by the liquid which fills each cell space uniformly via the apertures 9. In the Figure, the surface 6a should be considered the horizontal upper surface of the casing during filling and normal battery operation, and a vertical surface during activation. The electrolyte is preferably KOH and the cover 5 is preferably removable to allow sealing of the channel 8 after activation. The air electrode comprises a sheet of unsintered, porous p.t.f.e. supporting a Ni-plated mild steel mesh. A vinyl paint is applied on one side of the mesh and the painted side and the p.t.f.e. sheet are then hot-pressed together. The catalyst material of carbon or a Ag/C or Pt/C mixture is applied to the other side of the mesh. A flexible metal sheet is applied over the mesh together with a rubber block and the whole is hotpressed together to a thickness of 12 thousandths. Two such electrodes per cell are used and sandwich the zinc anode.
