20.500.12556/RUL-122196 Vpliv aditivov v žveplovo elektrodo na delovanje magnezijevega akumulatorja The influence of additives in the sulfur electrode on the performance of the magnesium battery Zaradi visoke energijske gostote, varnosti in nizkih stroškov glede na ostale akumulatorske sisteme, je sekundarni magnezijev akumulator zanimiv kandidat za prihodnje generacije hranilnikov električne energije. Glavna izziva, pred katerimi je postavljen razvoj magnezijevega akumulatorja, sta razvoj ustreznih elektrolitov in katodnega kompozita, ki bi omogočili čim večjo učinkovitost delovanja magnezij žveplovega akumulatorja. V diplomskem delu sem preučeval vpliv borovega nitrida (BN), ki smo ga dodali v žveplovo elektrodo na izboljšanje delovanja magnezijevega akumulatorja. Preizkušen je vpliv dodatka BN v kompozitno žveplovo katodo z namenom ugotoviti ali dodatek lahko vpliva na stabilnost delovanja. Rezultati meritev kažejo, da dodatek BN v žveplovo kompozitno elektrodo deloma izboljša specifično praznilno kapaciteto in stabilnost delovanja Mg-S akumulatorja in izboljša reverzibilnost delovanja žveplove elektrode ter zmanjša prenapetost. Due to its high energy density, safety and low cost compared to other battery systems, the secondary magnesium battery is an interesting candidate for future generations of electricity storage devices. The main challenges facing the development of the magnesium accumulator are the development of suitable electrolytes and cathode composite, which would enable the highest possible efficiency of the operation of magnesium in the sulfur accumulator. In my diploma thesis I studied the effect of boron nitride (BN), which was added to the sulfur electrode on the improvement of magnesium battery performance. The effect of BN additive on the composite sulfur cathode was tested to determine if the additive could affect the stability of operation. The measurement results show that the addition of BN to the sulfur composite electrode partially improves the specific discharge capacity and stability of the Mg-S battery operation and improves the reversibility of the sulfur electrode operation and reduces overvoltage. magnezijev akumulator aditivi žveplova elektroda borov nitrid magnesium accumulator additives sulfur electrode boron nitride true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-11-26 13:20:04 2020-11-26 13:20:13 2022-09-02 04:02:37 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 11761 41488899 Odlazek_hajdarpasic_Jakub_-_Vpliv_aditivov_v_zveplovo_elektrodo_na_delovanje_magnezijevega_akumu.pdf Odlazek_hajdarpasic_Jakub_-_Vpliv_aditivov_v_zveplovo_elektrodo_na_delovanje_magnezijevega_akumu.pdf 1 ACD02BABA31FEB564943C7224038559F 5a2d086bb32034a1d2d5be655c42488b08b836360c0c6b43b8e778bc990da85a 121d99fd-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=137376 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
