An alignment system uses a self-referencing interferometer that produces two overlapping and relatively rotated images of an alignment markers. Detectors detect intensities in a pupil plane where Fourier transforms of the images are caused to interfere. The positional information is derived from the phase difference between diffraction orders of the two images which manifests as intensity variations in the interfered orders. Asymmetry can also be measured by measuring intensities at two positions either side of a diffraction order.

Electro-winning of active metal (e.g., lithium) ions from a variety of sources including industrial waste, and recycled lithium and lithium-ion batteries is accomplished with an electrolyzer having a protected cathode that is stable against aggressive solvents, including water, aqueous electrolytes, acid, base, and a broad range of protic and aprotic solvents. The electrolyzer has a highly ionically conductive protective membrane adjacent to the alkali metal cathode that effectively isolates (de-couples) the alkali metal electrode from solvent, electrolyte processing and / or cathode environments, and at the same time allows ion transport in and out of these environments. Isolation of the cathode from other components of a battery cell or other electrochemical cell in this way allows the use of virtually any solvent, electrolyte and / or anode material in conjunction with the cathode. The electrolyzer can be configured and operated to claim or reclaim lithium or other active metals from such sources.
