This article is focused on lead-acid batteries used in hybrid electric vehicles and battery-powered vehicles. These cells work in specific conditions, particularly under partial charge referred to as PSOC and DoD. This fact is responsible for the premature loss of capacity cell lead-acid batteries and their short lifetime. The task of this work is to examine the effect of conductive ceramics as possible additives to the negative electrode active materials of lead-acid battery cells operating in a DoD, in order to prolong their life. This article compares the properties of experimental cells with varying amounts of Ebonex added in the positive active mass. For this experiment were selected electrodes in admixture with 0 wt.%, 0,15 wt.%, 0,46 wt.% and 0,78 wt.% of Ebonex.

This article deals with the surface morphology changes of the lead-acid battery working electrode during the cyclic voltammetry measured by using AFM. At first it was tested several methods of surface preparation of lead plates used in the measurement. Cyclic voltammetry was performed. The measured values are shown in the relevant figures.

This article discussed the climatic conditions during the curing process of the active mass of the lead-acid positive electrode battery. The results of the experiment achieved in the preparation of climatic chambers are presented in this article, they are compared with previous experiments, and they are mainly about optimization of temperature and humidity in the process of curing and drying.
