This bachelor's thesis deals with the preparation, thermal treatment, and electrochemical evaluation of organic materials based on pyrazine and quinone structural units as active materials for lithium and proton batteries. The aim of the study was to investigate the influence of thermal treatment on the electrochemical properties of the synthesized materials and to determine the most suitable preparation conditions for their application in different electrochemical systems. Within the scope of this thesis, five organic compounds were synthesized and subsequently thermally treated at different temperatures. The optimal thermal treatment conditions were determined by thermogravimetric analysis (TGA). The prepared materials were characterized using FT-IR and NMR spectroscopy. Composite electrodes were then fabricated, and electrochemical measurements were performed in lithium and proton batteries. The results showed that thermal treatment has a significant influence on the electrochemical properties of the materials, with its effect depending on the type of electrochemical system. The findings confirm that the optimal thermal treatment temperature depends on the type of battery. While higher treatment temperatures improve the performance of the materials in lithium batteries, untreated or only mildly thermally treated materials proved to be more suitable for proton batteries.
