Abstract: An exhaust stream treatment system includes a wet scrubber (210) having an inlet for accepting waste exhaust containing dichloromethane (201), a water inlet for accepting water (213) to be used to scrub the waste exhaust containing dichloromethane (201), a chamber in which the water is used to scrub the waste exhaust containing dichloromethane (201), an outlet for expelling dichloromethane-free exhaust, and a water outlet for expelling water and dichloromethane (211). The exhaust stream treatment system further includes a density separation vessel (220) having an inlet for accepting the water and dichloromethane output by the wet scrubber, an outlet for expelling dichloromethane (223), and a water outlet for expelling waste water (221). The system may further include a waste water return loop (224) from the waste water outlet of the density separation vessel to the water inlet of the wet scrubber. The system may further include a condenser (230) that condenses the dichloromethane-free exhaust and a condensed water return loop (232).

Abstract: Disclosed are self-standing calcined elements (e.g. bricks and tiles) comprising a cathode active material, and methods of preparation thereof. The process includes mixing a reagent with a metal precursor to form a precursor mixture, compressing the precursor mixture into a self-standing precursor element (e.g. brick and tile), and heating the self-standing precursor element (e.g. brick and tile) to form a self-standing calcined element (e.g. brick and tile) comprising a cathode active material.
