  • Publication number: 20240120566
    Abstract: The present disclosure relates to a method of recycling a positive electrode active material and a recycled positive electrode active material prepared by the same. More particularly, the present disclosure relates to a method of recycling a positive electrode active material, the method including step A of fragmenting a waste battery including a positive electrode, a separator, and a negative electrode to form waste battery scraps; step B of removing the negative electrode by jetting compressed air onto the waste battery scraps; and step C of treating the waste battery scraps from which the negative electrode has been removed with a solvent to remove the separator and obtain positive electrode scraps, and a recycled positive electrode active material prepared by the method.

  • Patent number: 7776554
    Abstract: There is provided a polydiacetylene supramolecule comprising diacetylene molecules, capable of immobilizing a receptor molecule having a thiol group. Since the polydiacetylene supramolecule has a receptor immobilized thereon having a thiol group, for example, an antibody, and thus shows color transition when reacting with a sample, an antigen can be detected through specific color transition of the polydiacetylene when employing in a receptor-ligand reaction, for example, an antibody-antigen reaction.
