“…The electrochemical studies of cadmium are closely related to its application in alkaline batteries, the electrodeposition of cadmium is particularly important in electronics, and the semiconductor properties of some cadmium chalcogenides . Reviews of the literature on cadmium electrodes[) -5] show that attention has been preferentially paid to the thermodynamics and kinetics of the electrochemical reactions in concentrated base solutions, particularly with porous electrodes, in relation to the performance of these electrodes in Ni-Cd battery cehs [6][7][8][9][10] . Despite the relatively abundant information available on the behaviour of plain cadmium in base solutions[l 1 -26], there are still relevant questions requiring further research related to the composition and structure of anodically formed films, the mechanism of the corresponding reactions, and the participation of soluble cadmium species in those reactions .…”

The anod nation of cadmium in NaOH solutions produces a hydrous cadmium hydroxidecadmium oxide layer and soluble cadmium species in solution . These processes are investigated through conventional voltammetry, potentiostatic, rotating ring disc electrode and complex voltammetric techniques by using NaOH solutions in the 0,01-1 M range at 25°C . The threshold potential of the anodic reaction is very close to the reversible potential of the Cd/Cd(OHh electrode. The overall anodic and cathodic reactions can be interpreted through a complex reaction model comprising a number of parallel reactions following the initial formation of Cd0H, a species at the electrode surface level . The relative contribution of each parallel reaction is determined by the concentration of OH -ion at the interface . The reaction model implies a composite structure ollayers starting from CdOHa4 at the electrode surface, and subsequent layers with an increase in the water content on approaching the outmost oxide layer. The water content of anodic layer should increase according to the pH and layer thickness and decrease on increasing the applied potential Under certain conditions the electrochemical reactions become ohmic resistance controlled . This fact presumably involves the formation of aged species and the onset of passivity .

“…According to the classical mechanistic explanation of thermal runaway, it results from sustained overcharging, which can lead to warming of the accumulator and, as a consequence, to a decrease in its internal resistance and an increase in the recharging current, which, in turn, increases the warming, and so on [1][2][3][4][5][6].…”

“…A review of the literature covering about the last 20 years concerning the investigation of various types of accumulators and the processes taking place in them has revealed that there have been very few papers dealing with the study of thermal runaway. However, this process is mentioned and discussed in quite a number of papers [1][2][3][4][5][6].…”
