Abstract : The present invention relates to batteries and more particularly to battery cells having nickel electrodes. In one aspect, this invention relates to novel nickel electrodes; in another aspect it relates to a method for fabricating nickel electrodes. Large shear stresses exist in sintered nickel hydroxide electrodes. The principal cause of these stresses is the mechanical inhomogeneity introduced by the electrode current collectors, which are substantially more rigid than the nickel sinter, and the molar volume change of the active materials during charge and discharge. It is an object of the present invention to provide a low shear electrode plaque. It is another object to provide a low shear nickel electrode. Further objects of the present invention include mehtods for fabrication of the above plaque and electrode. Other objects, aspects and advantages of the present invention will become apparent to those skilled in the art upon consideration of the accompanying disclosure.
