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.
