- Аннотация: The influence of the positive electrode properties on the activation time of the reserved chemicalpower sources based on the lead–perchloric acid–lead dioxide system is studied. Coatings of cathodes withlead dioxide obtained under various conditions are characterized by scanning electron spectroscopy, X-rayspectral microanalysis, X-ray photoelectron spectroscopy, and standard contact porosimetry. The improvement of the performance characteristics of the power sources including the ensuring of a short time of their activation at a low temperature is shown to be possible with the use of a lead dioxide nanoporous coating. To evaluate the applicability of cathodes for the manufacturing of power sources with a minimal activation time, a diagnostic principle is used that it based on the testing of the cathodes by chronopotentiometric measurements during their galvanostatic discharge. Pilot industrial samples of small-sized reserved power sources of the above-mentioned electrochemical system with unprecedented short activation time (less than 30 ms at temperature –50°С) were manufactured and tested
