20.500.12556/RUL-109854 Vpliv različnih anionov na delovanje magnezijevih akumulatorjev Magnezijevi akumulatorji naj bi bili tisti, ki bodo v prihodnosti predstavljali enega izmed načinov shranjevanja energije. Z uporabo magnezija v akumulatorskih aplikacijah lahko namreč dosežemo višje kapacitete pri manjši masi in precej nižji ceni v primerjavi z Li-ionsko grafitno anodo. So pa ti akumulatorji v zgodnji fazi razvoja. Ena od glavnih komponent, ki je precej nerazvita, so elektroliti. Od njih je namreč močno odvisno delovanje akumulatorja. Z dodatkom različnih soli se njihove lastnosti spremenijo. V diplomskem delu smo v eksperimentalnem delu preverili vpliv različnih anionov na delovanje akumulatorjev. Za osnovne magnezijeve elektrolite, ki smo jim nato dodajali različne litijeve soli, smo vzeli do zdaj že uveljavljen APC in pa dva nova nekorozivna elektrolita Mg(TFSI)2 in Mg(B(hfip)4)2. Delovanje akumulatorjev smo ocenjevali preko reverzibilnega odlaganja Mg na delovno elektrodo. Pripravljene elektrolite smo ocenjevali glede na coulombsko učinkovitost odlaganja in prenapetost pri odlaganju. Magnesium batteries are often seen as the future of energy storage. The use of magnesium metal anode inside a battery cell allows greater capacity at lesser mass and lower price when compared to Li-ion graphite anode. However, these batteries are in the early stages of development. One of the main components, that is currently underdeveloped, are electrolytes, as the performance and even research testing of batteries and potential battery materials depends on them. With the addition of different salts, their properties change. In the experimental part of diploma, we tested the influence of different anions on the performance of batteries. The basic magnesium electrolytes, to which different lithium salts were added, were previously established APC and two new non-corrosive electrolytes Mg(TFSI)2 and Mg(B(hfip)4)2. The performance of batteries was evaluated by reversible Mg deposition on the working electrode. The prepared electrolytes were evaluated for Coulombic efficiency and deposition overvoltage during Mg deposition process. magnezijevi akumulatorji APC Mg(TFSI)2 Mg(B(hfip)4)2 litijeve soli magnesium batteries APC Mg(TFSI)2 Mg(B(hfip)4)2 lithium salts true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-09-09 09:50:08 2019-09-09 09:50:12 2022-08-21 03:44:57 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 6409 1538395587 Suster_Janja_-_Vpliv_razlicnih_anionov_na_delovanje_magnezijevih_akumulatorjev.pdf Suster_Janja_-_Vpliv_razlicnih_anionov_na_delovanje_magnezijevih_akumulatorjev.pdf 1 B897F288B80ED7EC6AEDFC9D4D7FB4AF a62f81dc698d7a70e7dc57ca0b784e127836b1a7a755426d3db0a073f04d3876 f9c27775-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=121458 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
