Abstract

Simultaneous in situ photoacoustic, photoconductive, and electrochemical detection of species at the surface of the cadmium electrode has been demonstrated using both cw and pulsed light sources. The advantages of the cw and pulsed photoacoustic techniques were evaluated. Both techniques were applied to study the passivation of the cadmium electrode on high rate discharge. Cadmium oxide was identified on the electrode after passivation.
