Abstract: The use of metal hydrides as negative electrodes in alkaline rechargeable cells is becoming increasingly popular, due to several advantages offered by the metal hydrides over conventional anode materials (such as Zn, Cd) in terms of specific energy environmental cycle life and compatibility. Besides, the similarities in the cell voltage pressure characteristics, and charge control methods of the Ni-MH cells to the commonly used Ni-Cd point to a projected take over of 25% of the Ni-Cd market for consumer electronics by the Ni-MH cells in the next couple of years. Two classes of metal hydrides alloys based on rare earth metals (AB<SUB>5</SUB>) and titanium (AB<SUB>2</SUB>) are being currently developed at various laboratories. AB<SUB>2</SUB> alloys exhibit higher specific energy than the AB<SUB>5</SUB> alloys but the state of the art commercial Ni-MH cells are predominately manufactured using AB<SUB>5</SUB> alloys.
