  • Publication number: 20250070291
    Abstract: Recycling of lithium-ion batteries includes the steps of leaching a black mass including cathode and anode materials with a leaching agent, optionally including an oxidizing agent or reducing agent, to form an aqueous acidic leach solution of metal salts comprising metal salts and a plurality of impurity salts. The impurity salts are removed in various purification phases including treating with an oxygen-containing gas and optional electrodeposition and ion exchange steps, each at specified pH ranges. The amounts of the metal salts in the treated aqueous acidic leach solution are then adjusted to a desired ratio and coprecipitated to form a precursor cathode active material.

  • Patent number: 5455785
    Abstract: A memory card includes a circuit board bearing UV-erasable memory circuits enclosed in an opaque cover. The cover is provided with openings over the memory circuits. These openings can be covered or uncovered by a removable, opaque window shield. The memory card may be erased by removing the window shield from the openings in the cover and exposing the memory circuits to ultraviolet radiation transmitted through the openings. The window shield is then replaced to the position covering the openings in the cover after the erasable memory circuits are reprogrammed.
