Abstract: A method of preparing an electrode for a lithium-ion battery includes mixing a magnetic, electrically conductive material with a lithium conductive polymer; forming tubes of the polymer and magnetic, electrically conductive material; mixing the tubes with a slurry of an electrode material; coating a current collector with the slurry; and applying a magnetic field to the slurry to align the tubes within the slurry in relation to the current collector. The aligned tubes form electrical and ionic conductive pathways within the slurry. The tubes have a length less than half a thickness of the slurry.

Abstract: A method of preparing an electrode for a lithium-ion battery includes coating a slurry of electrode material onto a current collector, penetrating the slurry with rods coated with a polymer that expands when heated and shrinks when cooled, heating the rods coated with polymer while penetrated in the slurry. The polymer expands during heating, and then shrinks when cooled. The cooled rods and the polymer are removed from the slurry, leaving micro-pathways in the slurry where the rods and polymer penetrated.

Abstract: Provided are methods and apparatus for charging a lithium sulfur (Li—S) battery. The Li—S battery has at least one unit cell comprising a lithium-containing anode and a sulfur-containing cathode with an electrolyte layer there between. One method provides controlled application of voltage pulses at the beginning of the charging process. An application period is initiated after a discharge cycle of the Li—S battery is complete. During the application period, voltage pulses are provided to the Li—S battery. The voltage pulses are less than a constant current charging voltage. Constant current charging is initiated after the application period has elapsed.
