  • Publication number: 20210273220
    Abstract: A battery having a cathode and an anode with a three-dimensional porous framework. The anode includes an anode active material lithiated with a lithium source. The lithium particles from the lithium source are alloyed or intercalated with the anode active material during diffusion to form the three-dimensional porous framework. The porous framework provides reduced electrode deterioration due to volume expansion.

  • Publication number: 20190288271
    Abstract: The present invention provides a method of finely depositing lithium metal powder or thin lithium foil onto a substrate while avoiding the use of a solvent. The method includes depositing lithium metal powder or thin lithium foil onto a carrier, contacting the carrier with a substrate having a higher affinity for the lithium metal powder as compared to the affinity of the carrier for the lithium metal powder, subjecting the substrate while in contact with the carrier to conditions sufficient to transfer the lithium metal powder or lithium foil deposited on the carrier to the substrate, and separating the carrier and substrate so as to maintain the lithium metal powder or lithium metal foil, deposited on the substrate.
