Abstract: Porous, amorphous lithium storage materials and a method for making these materials are disclosed herein. In an example of the method, composite particles of a lithium storage material in an amorphous phase and a material that is immiscible with the lithium storage material are prepared. Phase separation is induced within the composite particles to precipitate out the amorphous phase lithium storage material and form phase separated composite particles. The immiscible material is chemically etched from the phase separated composite particles to form porous, amorphous lithium storage material particles.

Abstract: Lithium-ion cells and methods for producing such cells are provided. The lithium-ion cells include a lithium metal anode (LMA), a cathode, and an electrolyte between the LMA and the cathode. The LMA includes a current collector and a deformable layer on a surface of the current collector. The deformable layer is lithium-ion conductive and includes a polymeric material. The cathode has a lithium intercalation material. In some examples, lithium metal is plated on the deformable layer during charge of the lithium-ion cell to define a plated lithium layer between the deformable layer and the electrolyte, and a solid electrolyte interphase (SEI) layer forms on the plated lithium layer separating the plated lithium layer from the electrolyte.

Abstract: A method of forming a plurality of embossments in a sheet of metal includes: (i) placing the sheet onto a first surface of a die having a plurality of embossment cavities thereon, wherein the sheet has a bottom surface in contact with the first surface of the die and a top surface having an ablative coating formed thereon; and (ii) directing a laser beam at the ablative coating at one or more loci on the top surface of the sheet which correspond to the plurality of embossment cavities on the first surface of the die, so as to locally ablate the ablative coating at the one or more loci and turn the ablative coating at the one or more loci into plasma, thereby causing a plasma pressure shock wave at each of the one or more loci which presses the sheet into the embossment cavities to form the embossments.

Abstract: A method for using idle computing power of an electric vehicle includes sending the computing tasks and the task rates for performing the computing tasks to a vehicle controller of the electric vehicle and receiving an acceptance signal from the vehicle controller. The acceptance signal is indicative that the vehicle controller accepted to perform the computing tasks. The method further includes commanding a charging infrastructure to supply electrical power the electric vehicle while the vehicle controller performs the computing tasks.
