PERFORMANCE OF A PRISMATIC NICKEL / METAL-HYDRIDE (3.6 V / 13.9 AH) THREE-CELL BATTERY

The performance of a nickel metal-hydride 3.6 V / 13.9 Ah three-cell battery is reported in terms of charge/discharge characteristics. The metal-hydride negative electrodes were made of a stoichiometric AB5 alloy with composition [Mm(Al-Mn-Co-Fe-Ni)5] and nickel foam as current collector. The positive Ni(OH)2/NiOOH electrodes were made on sintered nickel carrier. The effect of varying charge and discharge rate was examined.
