Grammar For Pet Cambridge In Pdf Download In Pdf.This invention relates to electrolytic cells and particularly to anode structures used in such cells. The metal (e.g. lithium, sodium) anode in the electrolytic cell of the invention provides improved electrical contact to the cathode material. The electrolytic cell itself is generally of the symmetrical type with a fluid permeable membrane between the anode and cathode. The cell may include a separator, of fibrous nature, between the anode and cathode. One of the electrodes is immersed in an alkaline or acidic liquid. A current is passed between the electrodes to cause electrochemical reduction of the alkali metal. Oxygen is generated as a product of the electrochemical reaction. The reaction products are separated by an ion exchange membrane which is impermeable to oxygen. It is known to provide a spongy anode structure in which a material such as plastic is held together by a suitable spongy fibrous material. The spongy material provides good electrical contact with the cathode material as well as with the liquid electrolyte. The spongy material provides additional advantages. The alkali metal penetrates the spongy material to reach the cathode material. The penetration of the alkali metal into the spongy material improves the electrical conductivity of the material as well as providing a surface area for the penetration of an additional amount of alkali metal in the cell. It is also known to provide an anode structure of metal and spongy material. The spongy material may be attached to a cathode structure and the two components combined to provide a metal/spongy material cell. This type of cell is satisfactory for use in some applications but can be problematic in other applications. Metal/spongy material cells have a tendency to delaminate. This can occur when metal chips form at the interface between the metal and spongy material. The chips are readily displaced from the interface and can cause short circuits. Another problem encountered with metal/spongy material cells is "water treeing". Water can be produced in the spongy material which provides good electrical conductivity. The water can migrate from the spongy material into the alkaline solution. This may result in a loss of alkali
