The charge/discharge properties of commercial metal hydride alloy powder (MmNi3.81Mn0.41Al0.19Co0.76) is improved and modified by electroless plating nickel. The effect of concentration of reducing agent (Cr), concentration of complex agent (Cc), reaction temperature (T), reaction time (t), and the amounts of MH powder per volume (CMH) on the utilization of the modified MH alloy used as the negative electrode of Ni/MH battery is systematically studied. The utilization of modified MH alloy is mainly affected by Cr, Cc and t. The utilizations of MH alloys modified with condtions of T = 70 oC, t = 90 min, Cr = 20 g l-1, Cc = 20 g l-1 and CMH = 20 g l-1, respectively, are obtained to be 92.3, 64.7 and 23.6% at discharging rate of 1, 4, and 10 C. The utilizations of modified MH alloy are increased by 15.5, 45.6 and 19.8% compared with the pristine MH alloy for discharging rates of 1, 4 and 10 C, respectively.

A versatile thin layer spectroelectrochemical cell employing specular reflection of the incident light beam from the electrode surface is described. Its application to in-situ uv–vis and FTIR characterization of the products of electrochemical reactions and to thin layer voltammetry and coulometry as well as conventional cyclic voltammetry is demonstrated for the oxidation of tetraphenylporphinatozinc in dichloroethane/tetrabutylammonium perchlorate solution. The advantages and disadvantages of this type of cell as compared to more conventional sandwich type optically transparent thin layer electrodes are discussed.
