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).

Abstract: An earhook anti-snoring device is disclosed. The earhook anti-snoring device includes a casing, a base plate, a control unit, a sound-receiving device, a sound-generating device and a vibrating device. The base plate is arranged in the casing, and the control unit and the sound-receiving device are positioned on a side of the base plate. The position of the sound-receiving device corresponds to a hollow pipe arranged on the casing. The sound-generating device and the vibrating device are positioned on another side of the base plate and the sound-generating device is opposite to the sound-receiving device. The position of the sound-generating device corresponds to another hollow pipe arranged on the casing, and the sound-generating device is directed to an ear canal of a user along the hollow pipe.
