  • Protective coatings for lithium metal electrodes
    Patent number: 11430994
    Abstract: Double-layered protective coatings for lithium metal electrodes, as well as methods of formation relating thereto, are provided. The negative electrode assembly includes an electroactive material layer including lithium metal and a protective dual-layered coating. The protective dual-layered coating includes a polymeric layer disposed on a surface of the electroactive material layer and an inorganic layer disposed on an exposed surface of the polymeric layer. The polymeric layer has an elastic modulus of greater than or equal to about 0.01 GPa to less than or equal to about 410 GPa. The inorganic layer has an elastic modulus of greater than or equal to about 10 GPa to less than or equal to about 1000 GPa.

  • Methods for modifying the surfaces of a solid and microstructured surfaces with increased adherence produced with said methods
    Patent number: 8153254
    Abstract: Described are methods for surface modification of an object (10) in order to increase the adhesive power of the object, wherein the surface (11) is subjected to structuring so that a multitude of projections (12) are formed, each comprising a foot part and a head part, wherein the head part comprises a front surface (13) which faces away from the surface, wherein each projection (12) is made in a size such that all front surfaces (13) project to the same vertical height above the surface (11), and form an adherent contact surface (14) which is interrupted by mutual spacing between the front surfaces (13).
