description |
A primary challenge in developing rechargeable magnesium battery electrolytes is to
create a chloride-free electrolyte with a facile fabrication process. The chloride-based
additive is generally added to conventional magnesium electrolytes to improve their
compatibility with the magnesium anode. The additive, however, tends to induce
corrosion on the current collector of the cathode. This side effect increases the parasitic
reaction and cell degradation rate during the battery operation. Although several novel
magnesium electrolytes have been reported to be compatible with the magnesium
anode, even in a chloride-free electrolyte formulation, the mass scale production
viability of these electrolytes is low. To create a chloride-free simple to produce
electrolyte formulation, the thesis seeks to explore various combinations of
commercially available magnesium salts, additives, and solvents. The report shows that
by using the appropriate combination of non-passivating magnesium salt, moisture
scavenging additive, and ether-based solvent, a chloride-free electrolyte with good
compatibility with the magnesium metal anode can be created. The electrolyte was also
found to have high anodic stability on stainless steel and was also found to be
compatible with the copper sulfide cathode material at high temperature. |
