  • Publication number: 20240387826
    Abstract: An electrode active layer is disclosed that includes a network of high aspect ratio carbon elements (e.g., carbon nanotubes, carbon nanotube bundles, graphene flakes, or the like) that provides a highly electrically conductive scaffold that entangles or enmeshes the active material, thereby supporting the layer. A surface treatment can be applied to the high aspect ratio carbon elements to promote adhesion to the active material and any underlying electrode layers improving the overall cohesion and mechanical stability of the active layer. This surface treatment forms only a thin (in some cases even monomolecular) layer on the network, leaving the large void spaces that are free of any bulk binder material and so may instead be filled with active material. The resulting active layer may be formed with excellent mechanical stability even at large thickness and high active material mass loading.

  • Publication number: 20240289977
    Abstract: A three-dimensional object detection method includes: determining first plane coordinates of multiple landing points of a first object based on a projection frame of the 3D first object in a to-be-detected image, the to-be-detected image being captured by an image acquisition device; obtaining first world coordinate information based on a world coordinate system established based on position information and size information of the first object, the first world coordinate information including first world coordinates of the multiple landing points of the first object and first word coordinates of multiple vertices of the first object; and using coordinate conversion processing to obtain external parameter information that converts the world coordinates of the first object into camera coordinate based on the first plane coordinates, the first world coordinates of the multiple landing points of the first object, and the internal parameter information of the image acquisition device.
