  • Publication number: 20200144591
    Abstract: A dry electrode manufacturing process is employed for low cost battery through a dry mixing and formation process. A thermal activation renders the dry fabricated electrode comparable to conventional slurry casted electrodes. The dry electrode mixture results from a combination of a plurality of types of constituent particles, including at least an active charge material and a binder, and typically a conductive material such as carbon. The process heats the deposited mixture to a moderate temperature for activating the binder for adhering the mixture to the substrate, and compresses the deposited mixture to a thickness for achieving an electrical sufficiency of the compressed, deposited mixture as a charge material in a lithium-ion battery. In order to increase the bonding between the current collector and charge materials, an adhesive interlayer is applied through dry printing.

  • Publication number: 20190217387
    Abstract: Confining material particles during laser irradiation of the particles at ambient atmospheric pressure for additive manufacturing. In an embodiment, an optically transparent press permits transmitting a laser beam through the press to process material particles while simultaneously applying pressure to the particles. Confinement of material particles assists laser processing by providing densification, providing planarization, reducing the gap for material evaporation and transfer to a substrate, and the like.
