Latest Patents
Singh's latest patents include innovative designs for nickel metal hydride cells that are engineered for high rate and low temperature performance. One of his patents describes a metal hydride rechargeable cell that discharges at a rate of 8 C to 18 C while maintaining a cell temperature of 0°C. This design ensures that the voltage remains above 0.2 volts during the first half of the discharge curve. The cell features a negative electrode made from hydrogen storage alloy material, which has a specific particle size volume distribution. The manufacturing method he developed involves an activation protocol that includes a formation cycle, a heat treating step, and a cycling step, thereby avoiding unnecessary processing of the metal alloy material.
Another significant patent focuses on a method of forming CoOOH and NiOOH in a NiMH electrochemical cell. This formation procedure significantly reduces the time required to fully form such a cell. The process includes a first step of charging the cell at a constant voltage of 1.0 volt for approximately three hours, followed by a second charging step that can either apply a constant charge current or a constant voltage. This innovative approach results in higher utilization and improved cell capacities, especially after long-term storage or exposure to high temperatures.
