  • Calcium-metal alloy anode materials for reversible calcium-ion batteries
    Patent number: 11901550
    Abstract: Calcium ion batteries are provided. The calcium ion batteries include a cathode, an alloying anode composed of one or more intermetallic calcium compounds in electrical communication with the cathode; and an electrolyte disposed between the anode and the cathode. The intermetallic calcium compounds are intermetallic compounds of calcium and transition metals and metalloids.
    Type: Grant
    Filed: October 22, 2019
    Date of Patent: February 13, 2024
    Assignee: Northwestern University
    Inventors: Zhenpeng Yao, Christopher M. Wolverton
  • Anionic redox active lithium iron oxide based cathode materials for rechargeable lithium ion batteries
    Patent number: 11664526
    Abstract: Cathode materials for lithium ion batteries, lithium ion batteries incorporating the cathode materials, and methods of operating the lithium ion batteries are provided. The materials, which are composed of lithium iron oxides, are able to undergo reversible anionic and cationic redox reactions with no O2(g) generation.
