  • Anode interlayer for lithium batteries
    Patent number: 11715827
    Abstract: An all-solid-state battery comprises a lithium anode, a cathode, solid electrolyte and a protective layer between the solid electrolyte and the lithium anode. The protective layer comprises an ion-conducting material having an electrochemical stability window against lithium of at least 1.0 V, a lowest electrochemical stability being 0.0 V and a highest electrochemical stability being greater than 1.0 V. More particularly, when the solid electrolyte is LiSiCON, the electrochemical stability window is at least 1.5 V, the lowest electrochemical stability is 0.0 V and the highest electrochemical stability is greater than 1.5 V. When the solid electrolyte is sulfide-based, the electrochemical stability window is at least 2.0 V, the lowest electrochemical stability is 0.0 V and the highest electrochemical stability is greater than 2.0 V.

  • Method and System for Material Screening
    Publication number: 20210098084
    Abstract: A method for screening materials may include obtaining materials from a database. The method may include screening the materials to obtain a one or more screened materials. The method may include generating a training set based on the screened materials, validated experimental data, or both. The method may include establishing a machine learning screening model based on the training set, one or more target parameters, or both. The method may include applying the machine learning screening model to uncharacterized materials. The method may include outputting one or more materials having characteristics matching the target parameters.
