A crystallizer which incorporates a lamella settler and which is particularly applicable for use in batteries and power cells for electric vehicles or stationary applications. The lamella settler can be utilized for coarse particle separation or for agglomeration, and is particularly applicable to aluminum-air batteries or power cells for solving the hydrargillite (aluminum-hydroxide) removal problems from such batteries. This invention provides the advantages of very low energy consumption, turbulence, shear, cost and maintenance. Thus, due to the low shear and low turbulence of this invention, it is particularly effective in the control of aluminum hydroxide particle size distribution in the various sections of an aluminum-air system, as will as in other elecrochemical systems requiring separation for phases of different densities.
In an electrochemical system including a cell stack, an electrolyte storage/reaction chamber means, means for circulating electrolyte from said storage/reaction chamber means, through said cell stack, and back to said storage/reaction chamber means, and means for removing solid reaction products produced in said cell stack from the electrolyte, the improvement comprising:
An aluminum-air power cell comprising:
