Rechargeable magnesium-ion (Mg-ion) batteries are a promising alternative to lithium-ion (Li-ion) batteries, especially because they lack the dendrite formation that has led to safety issues in Li-ion technology. Key to the performance of a Mg-ion battery is its electrolyte, which enables the redox processes within the battery to occur smoothly and reversibly. For my internship, I characterized a nonaqueous alkoxide electrolyte previously developed in the Arnold battery lab. I learned to use equipment in the lab to fabricate, cycle and perform electrochemical tests on coin cells. I also had the opportunity to use the state-of-the-art facilities in the Andlinger Center for Energy and the Environment at Princeton to analyze samples. Working independently at all stages – from fabrication to analysis – was a challenging and rewarding experience that gave me valuable insight into the research process.
