摘要： This application provides a battery current collector and a preparation method thereof, a secondary battery, a battery module, a battery pack, and an electric apparatus. The battery current collector includes a foam metal layer (1) and a strength enhancement layer (2), where the strength enhancement layer (2) is a sheet-shaped metal layer, and the strength enhancement layer (2) and the foam metal layer (1) are stacked and metallurgically bonded, alleviating a problem of poor mechanical performance of current collectors in the related art. The strength enhancement layer (2) and the foam metal layer (1) are connected by metallurgical bonding, which helps ensure not only structural strength of the strength enhancement layer (2) and the foam metal layer (1), but also good conductivity between the strength enhancement layer (2) and the foam metal layer (1). Further, the manner of metallurgical bonding helps reduce production costs.

摘要： Methods of manufacturing monolithic components with complex design features and functionally graded properties in any spatial direction may include forming of outer shell with an additive manufacturing process, loading the shell with bulk material and exposing the loaded shell to a hot isostatic pressing (HIP) process. The combination of the additive manufacturing process and the HIP process forms a diffusion bond between the outer shell and the bulk material resulting in a monolithic component with functionally graded properties. The outer shell may include an exterior surface and an inner passage formed with relatively hard surfaces to accommodate fluids in a wellbore.
