Latest Patents

Martin G. Hake holds a patent for an electrochemical secondary cell. This invention involves a lithium/lithium manganese oxide secondary cell that employs a SWING system, commonly known as a 'rocking chair cell' type. The design features a positive electrode made from a metal gauze-reinforced, rolled electrode, and a negative electrode created by impregnating nickel foam with a paste of lithium-intercalating graphite. This configuration allows for electrodes that are three to four times thicker than those produced using traditional knife-coating techniques, making them particularly suitable for prismatic cell construction. By pre-rolling the empty nickel foam to specific thicknesses, the capacity per unit area of the negative electrode can be tailored to match that of the positive electrode. The rerolling of the impregnated nickel foam achieves optimal energy density and electrode capacity, with a porosity ranging from 50 to 60%.
