  • Publication number: 20250197234
    Abstract: The present invention has the advantage of recovering high-purity lithium hydroxide from a discarded sagger that is to be scrapped, by pulverizing the discarded sagger and then recovering nickel oxide and cobalt oxide, which are positive electrode active materials, through wet magnetic separation, and removing impurities through Al and Si precipitation reactions and evaporative concentration. Therefore, by using the method for recovering a positive electrode active material and lithium hydroxide from a discarded sagger according to the present invention, high value-added lithium and positive electrode active materials may be recovered and recycled from a discarded sagger that is scrapped during the manufacturing process of lithium secondary batteries and thus the method is expected to reduce the manufacturing costs of lithium secondary batteries.

  • Patent number: 12293042
    Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.
