Abstract
In this paper, the expression "electrochemical noise" is to be interpreted as the occurrence of microscopic fluctuations of the potential of an electrochemical cell. A study was done on a number of commercial lithium cells to evaluate the practicality of electrochemical noise measurement as a diagnostic for performance and/or safety. The survey was limited to the lithium based systems: sulphur dioxide, thionyl chloride and manganese dioxide. The cells were subjected to a programmeof storage, environmental and discharge conditions and then examined to determine if there had been any detectable effect on the electrochemical noise characteristics. While the study was of limited scope, it was nevertheless established that all cells exhibited some measurable electrochemical noise under certain conditions. The characteristics ofthe noise and its magnitude were influenced by many factors.
