Abstract
Thermal decomposition in a sealed thermal chamber were subjected to cadmium and oxide-nickel electrodes of nickel-cadmium batteries НКБ-15 и НКБН-6 with different service life. It is found that the amount of hydrogen in the oxide-nickel and cadmium electrodes increases with increasing batteries life. Consequently experimental results unequivocally prove, that hydrogen is accumulated in oxide-nickel and cadmium electrodes in process of operation of batteries. Moreover, in the new nickel-cadmium batteries, hydrogen in electrodes is absent. It is shown that at small terms of operation of the hydrogen content in the electrodes varies greatly. This is due to the different operating conditions of different batteries. At greater terms of operation (more than five years), the hydrogen content in the electrode is approximately the same.
Keywords: battery; nickel-cadmium; hydrogen accumulation; thermal runaway
