Abstract
The hydrogen storage alloys MmNi3.55Mn0.4Al0.3Co0.75-xFex (x=0.55 and 0.75) were used as negative electrodes in the Ni-MH accumulators. The chronopotentiommetry and the cyclic voltammetry were applied to characterize the electrochemical properties of these alloys. The obtained results showed that the substitution of the cobalt atoms by iron atoms has a good effect on the life cycle of the electrode. For the MmNi3.55Mn0.4Al0.3Co0.2Fe0.55 compound, the discharge capacity reaches its maximum of 210mAh/g after 12 cycles and then decreases to 190mAh/g after 30 charge-discharge cycles. However, for the MmNi3.55Mn0.4Al0.3Fe0.75 compound, the discharge capacity reaches its maximum of 200 mAh/g after 10 cycles and then decreases to 160 mAh/g after 30 cycles. The diffusion behavior of hydrogen in the negative electrodes made from these alloys was characterized by cyclic voltammetry after few activation cycles. The values of the hydrogen coefficient in MmNi3.55Mn0.4Al0.3Co0.2Fe0.55 and MmNi3.55Mn0.4Al0.3Fe0.75 are, respectively, equal to 2.96 x 10-9 and 4.98 × 10-10 cm2 s-1. However, the values of the charge transfer coefficients are, respectively, equal to 0.33 and 0.3. These results showed that the substitution of cobalt by iron decreases the reversibility and the kinetic of the electrochemical reaction in these alloys.
