Paper Title:
The Effect of High Charging Rates Activation on the Specific Discharge Capacity and Efficiency of a Negative Electrode Based on a LaMgAlMnCoNi Alloy
  Abstract

A nickel-metal hydride (Ni-MH) rechargeable battery has been prepared using a La0.7Mg0.3Al0.3Mn0.4Co0.5Ni3.8 alloy as the negative electrode. The maximum discharge capacity of the La0.7Mg0.3Al0.3Mn0.4Co0.5Ni3.8 alloy has been determined (350 mAh/g). Using a high starting charging rate (2857 mAg-1) an efficiency of 49% has been achieved in the 4th cycle. The alloy and powders have been characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD).
