摘要： A nickel positive electrode including an active material mixture mainly composed of a nickel oxide and an electrically conductive support, a metal and/or an oxide thereof including elements effective for increasing oxygen overvoltage, preferably at least one element selected from Ca, Ti, Nb, Cr, Y and Yb is contained in a conducting agent such as metallic Co and/or Co oxide added to supplement the electrical conductivity of the active material. By virtue of this construction, the decrease of charging efficiency caused by increase of battery temperature and decrease of the oxygen overvoltage with charging of the battery can be inhibited and the charging efficiency can be improved in a wide temperature atmosphere. Thus, a nickel-metal hydride storage battery of high capacity can be provided.

摘要： The present invention relates to a hydrogen storage alloy electrode composed of a hydrogen storage alloy having a CaCu5 region and a Ce2Ni7 region in the crystal structure and satisfies the relational formula: p:q=1:(4+a), where p is the sum of the mole fraction of an element occupying the Ca site of the CaCu5 region and the mole fraction of an element occupying the Ce site of the Ce2Ni7 region, q is the sum of the mole fraction of an element occupying the Cu site of the CaCu5 region and the mole fraction of an element occupying the Ni site of the Ce2Ni7 region, and −0.2≦a≦0.4. Accordingly, although the hydrogen storage alloy electrode contains a little or no Co, it is possible to obtain an electrode having little deterioration due to pulverization of the alloy and a high capacity.

摘要： A battery accommodates elements for electromotive-force within a metal case. This metal case is a metal case having a bottom wherein the bottom thickness/side thickness ratio has a value of 1.2-4.0 and has a cylindrical, prismatic or similar shape. The metal case is constructed of a metal material whose chief constituent is aluminum. Furthermore, it is desirable that a multiplicity of shallow grooves perpendicular to a bottom face are formed in at least a battery inside face of the metal case and moreover that a nickel layer is provided on the battery inside face. The metal case is made by DI processing involving drawing and ironing, to have a value of bottom thickness/side thickness ratio which was hitherto unavailable,i.e., 1.2-4.0 can be obtained.
