  • Porous sheets and method of making same from porous carbon nanotubes and decomposing microorganisms
    Patent number: 11646403
    Abstract: A method of preparing a porous sheet includes mixing a matrix material dispersion including a matrix material dispersed in a first dispersion medium with a microorganism dispersion including microorganisms in a second dispersion medium, to form a mixture. The first and the second dispersion media are removed from the mixture to form a matrix sheet, and the microorganisms are decomposed from the matrix sheet to form the porous sheet.

  • Thin cathode for micro-battery
    Patent number: 11205777
    Abstract: Batteries include an anode, an electrolyte having a high solubility for lithium ions and oxygen, and a cathode formed on a substrate. Lithium ions migrate from the anode through the electrolyte to form Li2O2 at a surface of the cathode. A current collector positioned in the electrolyte, the electrolyte separating the anode from the cathode.
