Abstract:

The nickel composite plaque is a new concept in sintered substrates for application in alkaline energy storage systems. The plaque is fabricated from nickel coated graphite fibers which, upon sintering in reducing atmosphere, produces a strong lightweight structure of open porosity suitable for electrode use. The four test areas of this report include tensile strength, porosity, electrical resistivity and SEM micrography of the plaque structure. Porosities of 55 to over 90 percent void volume are achievable with the composite plaques, while maintaining structural integrity. Porosimetry measurements indicate approximately a 4X greater than mean pore size and 1.5X broader pore size distribution than commercial powder sinter. Tensile strengths were measured as a function of nickel coating thicknesses.
