Electrodes for electrochemical cells current generating cells and rechargeable accumulators

Electrodes using essentially insoluble active material are disclosed which can be used in a variety of electrochemical cells and rechargeable accumulators. Plastic materials are used to ensure porosity and strength and to sinter the electrode ingredients and active material together. Details of the essentially insoluble compound active material are disclosed and of an electrolyte recommended for use with the electrodes. Aspects of this invention are applicable particularly to Ni-Cd, Ag-Cd, Ag-Zn, Ni-Fe, Ni-Zn, Metal-Air, fuel or solar cells.
