  • Patent number: 7851086
    Abstract: Disclosed is an electrode material for a lithium secondary battery, a lithium secondary battery comprising the same, and a method for preparing the electrode material for a lithium secondary battery. The electrode material for a lithium secondary battery includes Si as a principal component, wherein the interplanar spacing of an Si (111) surface is between 3.15 ?and 3.20 ? using X-ray diffraction. This is achieve by first alloying Si with an element selected from the group consisting of Al, B, P, Ge, Sn, Pb, Ni, Co, Mn, Mo, Cr, V, Cu, Fe, Ni, W, Ti, Zn, alkali metals, alkaline earth metals, and combinations thereof, and then eluting X from the resulting alloy.

  • Publication number: 20060014056
    Abstract: A fuel cell system comprises a reformer for generating hydrogen from fuel, at least one electricity generator for generating electric energy through an electrochemical reaction between hydrogen and oxygen, a fuel supply unit for supplying the fuel to the reformer and an oxygen supply unit for supplying oxygen to the electricity generator. The reformer includes a main body which has an inner space with a reformer inlet and a reformer outlet. A reaction section is disposed within the inner space of the main body. The reaction section includes a heat-generating element for generating thermal energy from externally applied energy such as electrical current. The heat-generating element has a corrugated structure with a catalyst layer formed on the surface. The corrugated structure defines a plurality of flow passages for the fuel and encourages both even flow distribution and turbulent flow.

  • Patent number: 5563008
    Abstract: A formation method of nickel electrode for secondary alkaline batteries which comprises charging nickel electrodes, discharging the nickel electrodes to an amount equal to their full capacity, overdischarging the nickel electrodes under the same conditions with the previous discharging step, assembling a cell with the nickel electrodes and zinc anodes and alternating the cell between charging and discharging. Property deviations among the obtained battery articles are much reduced, so that batteries can be manufactured with uniform properties. The overdischarge of the nickel electrodes ahead of the cell assembling prevents the separator from being oxidized by gas generation.
