Aswin K. Manohar, Chenguang Yang, Souradip Malkhandi, Bo Yang, G. K. Surya Prakash and S. R. Narayanan,z Abstract Rechargeable iron-based alkaline batteries such as iron – air and nickel – iron batteries are attractive for large-scale electrical energy storage because iron is inexpensive, globally-abundant and environmentally-friendly. Further, the iron electrode is known for its robustness to repeated charge/discharge cycling. During manufacturing these batteries are charged and discharged 20 to 50 times during which the … Continue reading →

Stage 1 A preliminary test applying a carbonyl nickel coating to several substrates was performed at CVMR Corporation in Toronto, Ontario, Canada (see Appendix 1-B in the Introduction Chapter). Zinc alloy A190, copper alloy C110 and low-carbon steel surfaces were prepared by depositing carbonyl nickel at 175 °C (347 °F). The coated specimens were subjected to various thermal exposures to increase interface bonding and to reduce residual stresses. The specimen geometries comprised planchets, approximately … Continue reading →

1.Background The carbonyl or Mond process was discovered in 1884 when Ludwig Mond noticed that hot carbon monoxide (CO) gas would severely corrode nickel. The carbonyl process exploits the ability of CO to form compounds with many of the transition elements in Groups VIA to VIIIA of the Periodic Table of Elements. The process works particularly well for nickel and it is reversible. That is, nickel can be extracted from a substrate, or deposited … Continue reading →

CVMR’s process for refining of Ferralite and Saprolite ore maximizes value of the ores by producing value added products. Ferralite ore A typical Ferralite ore contains 40-45% of Iron, 1-1.5% of Nickel, 0.04-0.10% of Co (potentially Copper, PGE and Rare earth elements). * Published with permission of the client.
