  • 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: 20230352368
    Abstract: A power module is disclosed. The power module includes a first conductive plate, a first power component, and a second power component. The first conductive plate has a first side and a second side opposite to the first side; The first power component is disposed at the first side. The second power component is disposed at a first location of the second side distinct from a second location of the second side. The second location is configured to transfer most heat from the first power component to the second power component if the second power component is disposed at the second location.

  • Patent number: 8497374
    Abstract: A synthetic process for producing bortezomib comprising converting racemic boronic esters, such as the pinacol ?-aminoboronic ester, into mixtures of diastereomers [6] by reaction with a suitably protected L-phenylalanine derivative (see Scheme 3), such as N—BOC-L-phenylalanine. The protecting group of the L-phenylalanine moiety is then removed, such as by reacting the diastereomers [6] with an acid, such as hydrochloric acid, to form a mixture of amine salt diastereomers [7] which is then subjected to conditions under which the desired diastereomer (R,S)-[7] is selectively isolated, such as by crystallization, chromatography or stereoselective hydrolysis. The separated desired diastereomer (R,S)-[7] is then converted into bortezomib or bortezomib anhydride.
