Internal Pressure in Ni/Me Hydride Cells (PDF - 101KB)
The effect of high surface area of T210, T210H and standard battery grade T255 nickel powders on the internal pressure of Ni/Me hydride (MH) cells is studied in starved cells.
Pasted Ni(OH)2 Electrodes in High Drain Rate Ni-based Batteries (PDF 656KB)
Testing results showed that using T210 extra fine filamentary nickel powder as an additive, significantly improves the active mass utilization, gravimetric capacity and volumetric capacity of pasted Ni(OH)2 electrodes at high rates.
Superior Nickel Foam Production: Starting from Raw Materials Quality Control (PDF - 641KB)
The paper describes the two methods of nickel foam production employed by Inco as of 2005 and discusses the importance of raw materials quality (polyurethane foam substrate, nickel feed) in the manufacturing process to achieve superior quality final product.
New Additives For Nickel Electrode Batteries (PDF - 2714KB)
A description of Inco's latest products for pasted nickel foam batteries. A summary of the features of nickel foam and the use of nickel powder additives is provided, as well as some preliminary data showing the benefits of Inco's newest powder, Type 240(TM), for enhancing electrical conductivity in mixtures.

Magnetic Properties of Organic Coatings Containing Nickel, Nickel-alloy and Stainless Steel Flakes (PDF - 116KB)
Dr. AC Hart, Warsaw Coating Conference, November 2004.
Reviews the magnetic properties of flake pigments made from the following compositions: Nickel, 97/3 Nickel Aluminum, 2Mo81Ni Permalloy and 316L Stainless Steel.
EMI Shielding
Nickel-Coated Graphite - an answer to electronic shielding problems (PDF - 740KB)
Dr Anthony C. Hart, Hart Coating Technology, December 2005.
Dr Hart compares the performance characteristics of Nickel Coated graphite and Silver coated products. He concludes that in conductive gaskets, Nickel Coated Graphite offers comparable shielding effectiveness, superior corrosion resistance and significantly lower cost versus silver coated glass, copper and aluminum.
