  • Patent number: 12006970
    Abstract: A ball retainer is provided. The ball retainer includes a chain belt, a hook portion, and a recess portion. The chain belt has a first end and a second end. The hook portion is disposed at the first end. The recess portion is disposed at the second end. An outer circumferential side and an inner circumferential side are formed after the hook portion of the ball retainer is snapped into the recess portion. During operation of the ball retainer after the hook portion is snapped into the recess portion, an acting force is applied to the chain belt so that the hook portion is disengaged from the recess portion. During operation of the ball retainer after the acting force disappears, the first end and the second end of the chain belt approach each other so that the hook portion is accordingly snapped into the recess portion.

  • 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).
