    摘要: A copper-manganese mixed oxide cathode material, which is suitable for use in a cathode of an electrochemical cell, has the formula Mn x CU y O z ,•nH 2 O, wherein the oxidation state of Cu is between about + 1 and about +3, the oxidation state of Mn is between about +2 and about +7, x is equal to about 3-y, y is less than about 3, z is calculated or experimentally determined, using means known in the art, based on the values of x and y, as well as the oxidation states of Mn and Cu, and nH 2 O represents the surface and structural water present in the mixed oxide material. An electrochemical cell comprises an anode, a cathode, and a separator disposed between the anode and cathode, and an electrolyte in fluid communication with the anode, the cathode and the separator, wherein the cathode comprises the noted cathode material. The invention still further relates to such an active cathode material, or an alternative cathode material, wherein the copper-manganese mixed oxide comprises a defect spinel-type structure, which is also suitable for use as a cathode component of an alkaline electrochemical cell.

    摘要: The present disclosure is directed to an electrochemical cell, preferably a zinc air cell, with improved voltage and reduced polarization. The combination of an anode corrosion inhibitor with a surfactant system yields enhanced cell voltage and capacity for the cell that are above the individual contributions of the corrosion inhibitor and the surfactant system. The surfactant system comprises a hexyl diphenyl oxide disulfonic acid surfactant and at least one amphoteric surfactant.

    摘要: An inner cutter for a rotary shaver generally includes a blade (300) having a base plate (304) and a plurality of fingers (308) unitarily formed with and bent upwardly relative to the base plate. Each of the fingers includes a front surface (336), a back surface (338) opposite the front surface, and a top surface (332) extending from the front surface to the back surface. The front surface and the top surface define a cutting edge, and the front surface has a curvilinear profile portion (348) beneath the cutting edge.
