Anne Co obtained her B.Sc. in Applied Chemistry and Ph.D. in Chemistry with a specialization in Electrochemistry under Professor Viola Birss from the University of Calgary, Canada. She then joined National Research Council Canada in Ottawa with an NSERC Visiting Fellowship and later served as a Research Associate. In 2008, she continued her postdoctoral studies with Cynthia Friend at Harvard University with a Mary Fieser Fellowship Award. Anne Co’s current research interest is in investigating the properties of electrocatalytic materials and processes for energy conversion and storage. She joined the Ohio State Chemistry Department in August of 2010.

Fifth Year Student

M.Sc. (Chemistry) 2015, East Tennessee State University (ETSU), Johnson City, TN

Current project motivation: The call to switch the energy source from fossil to renewable to avoid an environmental calamity is clearly outlined in the Paris Climate Agreement, and in other to achieve such stringent international agreement, significant advancement in the field of material engineering and analysis is required. Energy harvesting from the sun and wind have proven very significant, but these sources of energy are not always available 24/7, which means we need some kind of energy storage device to complement these energy production farms. This is where the battery team of our lab comes in.

Current Project: I am currently working on making and characterizing high entropy materials for high-power lithium-ion batteries. Characterization techniques might include XRD, SEM/TEM, electrochemical methods, etc.

One of the other important aspects in our battery team which I am also working on involves the understanding of the lithiation mechanism of the materials I make, or existing materials in other to improve their performance. I use Solid-state nuclear magnetic resonance spectroscopy (ssNMR) for mechanistic studies.
