A solid, printable electrolyte enables lithium-ion batteries to take many shapes Engineers dreaming up new pacemakers, watches, or whatever wearable gadgets come after Google Glass have to tailor their designs around existing battery shapes—typically cylinders, pouches, or rectangles. But a team of researchers hopes their fully printable, flexible lithium-ion batteries will one day free designers Read more about Flexible Lithium-Ion Batteries[…]
Room temperature ionic liquids or simply ionic liquids (some even call them molten salts) can act as a great solvent for electrochemistry but they bring along a challenge of what to use for the reference electrode. Traditional saturated calomel or Ag/AgCl reference electrodes use water as a solvent which can cause trouble for ionic liquids. Read more about Reference Electrode for Ionic Liquids[…]

In the previous post (Electrochemical Corrosion Measurements Primer) we pointed out that Icorr cannot be measured directly. In many cases, you can estimate it from current versus voltage data. You can measure a log current versus potential curve over a range of about one half volt. The voltage scan is centered on Eoc. You then fit the measured data to a theoretical model of the corrosion process.
The model we will use for the corrosion process assumes that the rates of both the anodic and cathodic processes are controlled by the kinetics of the electron transfer reaction at the metal surface. This is generally the case for corrosion reactions. An electrochemical reaction under kinetic control obeys Equation 1-1, the Tafel Equation.
NSF Creates industry electrochemical research center at Ohio University
The Center for Electrochemical Engineering at Ohio Univ.’s Russ College of Engineering and Technology has received a National Science Foundation (NSF) award to establish a new industry university cooperative research center in Athens, Ohio, with partner site Washington University-St. Louis.
Led by Russ Professor of Chemical Engineering and Center for Electrochemical Engineering Director Gerri Botte, research at the new Center for Electrochemical Processes and Technology (CEProTECH) will focus on electrochemical alternatives to conventional chemical and biological processes, with the goal of enhancing advanced production capabilities, via a consortium model.
Consortium members will have access to pre-competitive, industry-driven research results and a dedicated 20,000-square-foot facility, located on Mill Street in Athens, Ohio, with more than $7 million in state-of-the-art equipment and infrastructure; students with specialized expertise in electrochemical engineering; and relationships with faculty, government labs and agencies, and other industry members.
