Lead-acid batteries are still widely utilized in numerous applications due to their cost-effectiveness and well-established development despite the increasing use of newer battery systems such as Li-ion batteries. The range of options for their applications is broad, necessitating specific adaptations for each usage scenario. This is achieved to a great extent through various battery technologies and composition of anode and cathodes. In this thesis we focused on the latter and aimed to determine the suitability of different types of cathodes, manufactured by TAB d.d., for the desired mode of use. Specifically, under certain conditions (relative humidity and temperature), we sought to validate the cathode preparation process from the initial mixing phase, where we varied the initial composition, to the technological processes of curing and drying, during which the structures transform from one form to another. The composition itself was determined using X-ray powder diffraction. Furthermore, we measured porosity and gravimetrically determined the final value of PbSO4 to verify the effectiveness of the initial paste preparation, ensuring that all acid had reacted. Throughout the maturation and drying phase, we monitored moisture content and free Pb using a moisture meter and gravimetry, respectively, aiming to achieve the lowest possible values for both parameters. All these parameters needed to fall within the expected range for us to assert that the cathodes were suitable for further processing.
