  • Publication number: 20230212770
    Abstract: The present invention provides an extracting method of extracting nickel from laterite minerals. The extracting method comprises steps of gathering laterite minerals, placing electrodes into a solution, heating the solution to 75 degrees Celsius, placing the electrodes within the solution, applying a constant current, shutting off the current, filtering the solution, pouring an alkaline solution into the solution, cooling down the solution at room temperature, cooling down the solution to 0 degrees Celsius, filtering the solution, and immersing the electrodes into the solution, adding additional materials to the solution.

  • Publication number: 20200212433
    Abstract: Systems and methods for manufacturing an electrode is provided. An example method may comprise disposing, by a blade, a slurry onto a surface of a current collector, the slurry including an active material and a solvent, applying, by an electric field source, an electric field between the blade and the current collector, and drying the slurry applied to the surface of the current collector to remove the solvent. The electric field is applied continuously while the slurry is disposed onto the surface of the current blade. The electric field affects the structure of portions of the slurry by causing a Van der Waals interaction and a polarization attraction between the active material and the current collector. The slurry may include of 95% graphite, 3% of a binder, and 5% of reduced graphene oxide. The solvent may include 4 to 1 mixture of water and isopropyl alcohol.

  • Publication number: 20200212429
    Abstract: External forces are applied to a slurry mixture to achieve a more organized slurry structure in the manufacturing of an electrode. A slurry is generated with paramagnetic materials that exhibit magnetic properties when a magnetic field is applied to the slurry. The slurry with the paramagnetic materials is applied to a current conductor, and then a magnetic field is applied to the slurry, for example during an electrode drying process. By applying a magnetic field, the paramagnetic material orientation can be aligned into a more organized structure. In some instances, the alignment creates a porous structure or gap between pillars that form within the dried slurry material. The dried, porous slurry structure allows for electrolyte wetting and ionic accessibility that is greatly improved over electrodes manufactured using typical techniques.
