20.500.12556/RUL-186146 Termično obdelane organske molekule kot aktivni material v baterijah Thermally treated organic molecules as active materials in batteries Diplomsko delo obravnava pripravo, termično obdelavo in elektrokemijsko ovrednotenje organskih materialov na osnovi pirazinskih in kinonskih strukturnih enot kot aktivnih materialov za litijeve in protonske akumulatorje. Namen raziskave je preučiti vpliv termične obdelave na elektrokemijske lastnosti sintetiziranih materialov ter določiti najprimernejše pogoje priprave za uporabo v različnih elektrokemijskih sistemih. V okviru diplomskega dela je bilo sintetiziranih pet organskih spojin, ki so bile nato termično obdelane pri različnih temperaturah. Optimalni pogoji termične obdelave so bili določeni s termogravimetrično analizo (TGA). Pripravljene materiale smo karakterizirali z metodama FT-IR in NMR, nato pa pripravili kompozitne elektrode in izvedli elektrokemijske meritve v litijevih in protonskih akumulatorjih. Rezultati so pokazali, da termična obdelava pomembno vpliva na elektrokemijske lastnosti materialov, pri čemer je njen učinek odvisen od vrste elektrokemijskega sistema. Rezultati diplomskega dela potrjujejo, da je izbira optimalne temperature termične obdelave odvisna od vrste akumulatorja. Medtem ko višje temperature izboljšajo delovanje materialov v litijevih akumulatorjih, se v protonskih akumulatorjih, kot primernejši izkažejo nežgani, torej netermično obdelani materiali. 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. organski aktivni materiali termična obdelava litijevi akumulatorji protonski akumulatorji elektrokemijske lastnosti pirazinske spojine kinonske spojine. organic active materials thermal treatment lithium batteries proton batteries electrochemical properties pyrazine compounds quinone compounds. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-27 11:05:03 2026-08-27 11:05:08 2026-09-10 12:51:51 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 26170 290671875 Bozic_Anabela_-_Termicno_obdelane_organske_molekule_kot_aktivni_material_v_baterijah.pdf Bozic_Anabela_-_Termicno_obdelane_organske_molekule_kot_aktivni_material_v_baterijah.pdf 1 235A38A0F2D77EB05A2D0679D7F50BD3 404e8f826877e32c4a3f374c78a296a0ff478f089b802d7ff8a56139f1969942 fd541cca-a1f5-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245246 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
