  • Publication number: 20240128531
    Abstract: The present disclosure discloses a method for recycling all types of lithium batteries. First, the lithium battery waste is acid-leached to obtain a solution containing most of metal ions. After filtering, the solution is separated from the remaining solids, and then the obtained solution is subjected to separate precipitation many times. After separately adjusting the pH value of the solution many times, adding precipitants with a high selectivity ratio, and matching with filtration and separation reaction, all ions in the lithium battery waste are sequentially precipitated in forms of iron phosphate (FePO4), aluminum hydroxide (Al(OH)3), manganese oxide (MnO2), dicobalt trioxide (cobalt oxide, Co2O3), nickel hydroxide (Ni(OH)2), and lithium carbonate (Li2CO3).

  • Publication number: 20240071813
    Abstract: A dielectric structure is formed over a layer than contains a conductive component. An opening is formed in the dielectric structure. The opening exposes an upper surface of the conductive component. A first deposition process is performed that deposits a first conductive layer over the dielectric structure and partially in the opening. A treatment process is performed on a first portion of the first conductive layer formed over the dielectric structure. The treatment process introduces a non-metal material to the first portion of the first conductive layer. After the treatment process has been performed, a second deposition process is performed that at least partially fills the opening with a second conductive layer without trapping a gap therein.
