Abstract: A process (10) for the treatment of a lithium containing material, the process comprising the steps of: (i) Preparing a process solution from the lithium containing material (12); (ii) Passing the process solution from step (i) to a series of impurity removal steps (36) thereby providing a substantially purified lithium chloride solution; and (iii) Passing the purified lithium chloride solution of step (ii) to an electrolysis step (70) thereby producing a lithium hydroxide solution.

Abstract: An alkaline manganese cell--which is generally a rechargeable cell, but which may also be a primary cell--is provided, having an anode composition where the anode comprises an admixture of amalgamated zinc particles, zinc oxide and metallic copper. The metallic copper is finely divided and has a large surface area, so that the copper is distributed throughout the anode and forms an electrically conductive, low resistance structure within the anode. The metallic matrix within the anode takes the appearance of a sponge, and provides for conductivity within the anode at all stages of charge and discharge of the cell. Especially in the anode of a secondary cell, the cell will exhibit an overcharge reserve because there is a sufficient amount of zinc oxide in the anode, and it will exhibit an over discharge reserve because of the presence of metallic copper in the anode. Several processes for preparation of the zinc oxide/copper mixture are discussed, including several different chemical and electro-chemical reactions which may be followed. The preparation of the mix is exothermic, and the mixture should be kept in such a manner as to preclude its exposure to oxygen.
