Abstract: A cathode composite layer for an ASSB cell comprises cathode active material, a solid electrolyte, and conductive pathways. Each conductive pathway comprises a cylindrical carbon nanostructure having a first end and a second end with an exterior wall extending between the first end and the second end, and an insulating sheath covering the cylindrical carbon nanostructure except in an uncovered portion of the cylindrical carbon nanostructure, the uncovered portion being the first end and a first portion of the exterior wall directly adjacent the first end and the second end and a second portion of the exterior wall directly adjacent the second end.

Abstract: An electrode is provided that includes a current collector, at least one column and an electrode material. The at least one column is formed of a foam material. The electrode material is disposed on the current collector and includes an electrode active material. Each of the at least one column is disposed within and extending from a surface of the current collector.

Abstract: An energy storage device is provided that includes a first electrode, a second electrode, and a polymer electrolyte membrane disposed between the first electrode and the second electrode. The polymer electrolyte membrane includes a copolymer network including a polyoxide and a polysulfide. The polymer electrolyte membrane is prelithiated by deep discharging of the battery of in a voltage range of ?0.5 V to 5.0 V such that the polymer electrolyte membrane after deep discharging includes additional lithium ions stored therein as compared with prior to deep discharging.

Abstract: A battery is provided that includes a cathode current collector, a cathode, a solid electrolyte, an anode current collector and an elastic support. The elastic support is provided on at least one of the cathode current collector and the anode current collector. The elastic support comprises an elastic polymer and nanotube springs provided within the elastic polymer.

Abstract: A coating layer for a substrate includes a coating material. The coating material includes graphene and/or graphene derivatives that reflect and/or absorb an electromagnetic (EM) wave having a frequency of above 20 GHz. The coating layer is deposited on a surface of the substrate.

Abstract: The present disclosure relates to a method for storage or transportation of graphene oxide. The method for storage or transportation of graphene oxide comprises the steps of: carrying out wet spinning of a graphene oxide spinning solution to a coagulating bath to obtain graphene oxide pellets; drying the obtained graphene oxide pellets; storing or transporting the dried graphene oxide pellets; and redispersing the stored or transported graphene oxide pellets.
