  • Patent number: 5374491
    Abstract: There is now provided an improved manufacturing method for increasing the active material filling density in a small DTR reticulated nickel sheet. The nickel sheet has desirable physical properties such as resistance to breakage and crushing, in repeated bending. This resistance can be for both the surface area and the central area, in the thickness direction of the sheet. Such small DTR sheet has not previously been preferred as a battery electrode material because of a smaller filling density using conventional methods. There is now provided a battery electrode having high filling density of active material, high utilization rate of the impregnated active material and high capacity density with long life. Furthermore, a method of producing such small DTR of reticulated nickel sheet in a continuous and economical manner is disclosed.
