  • Catalyst system for advanced metal-air batteries
    Patent number: 10978703
    Abstract: The disclosure relates generally to batteries. The disclosure relates more specifically to improved catalyst systems for metal-air batteries. A metal-air battery comprising: an anode comprising a metal; a cathode comprising at least one transition metal dichalcogenide; and an electrolyte in contact with the anode and the transition metal dichalcogenide of the cathode, wherein the electrolyte comprises at least 50% by weight of an ionic liquid, is disclosed herein.
    Type: Grant
    Filed: December 14, 2015
    Date of Patent: April 13, 2021
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Amin Salehi-Khojin, Bijandra Kumar, Mohammad Asadi
  • Methods for synthesizing carbon nanocages
    Patent number: 10584033
    Abstract: A method for synthesizing carbon nanocages, including N-doped carbon nanocages, includes a first step of forming a solution including a metal salt and an organic carbon source; a second step of drying the solution to obtain a precursor powder; and a third step of annealing the precursor powder to obtain a nanocage including a metal nanoparticle surrounded by a carbon shell. The metal nanoparticle is then removed from the carbon shell by applying an acid solution.
