Using stepwise potentiodynamic cycling with observations of the chronoamperometric responses, we demonstrated different behaviors for Co additives in nickel oxy-hydroxides electrodes (NOE), depending on their form: either co-precipitated or post-adde

The evolution of cobalt hydroxide used as a coating for nickel hydroxide electrodes has been studied as a function of the redox potential window and upon cycling. From both chemical and electrochemical studies, it is shown that (i) upon deep discharg

Cobalt is usually co-precipitated with nickel to improve the nickel hydroxide electrode capacity. Herein, we present the acquirement of β-type mixed Ni/Co phases by three different synthetic routes. The first method consists of the electrochemical r

As an attempt to understand better how cobalt hydroxide additives improve the nickel electrode performance, the Co ( OH ) 2 / CoOOH redox system has been investigated through electrochemical cycling starting from a commercial Co ( OH ) 2 sample. A st

The Ni/H 2 self-discharge kinetics were studied by means of Ni/H 2 cells equipped with a pressure sensor to determine the time-dependence of cell pressure. The cell pressure variation was found to depend strongly upon cell state of charge (e.g., whet

To investigate the self-discharge mechanism in Ni/H 2 cells, the interactions of hydrogen with the β-NiOOH and γ-NiOOH nickel oxyhydroxide phases were simulated in a water-loaded autoclave as functions of both temperature and pressure. Under such c

A study of the curing reaction involved in the positive plate of the lead-acid battery has been undertaken. The variation of the different parameters of the curing reaction has shown the possibility of changing the 4BS needles dimensions. In particul
