This is a Livestream Q&A/Ask Us Anything for answering YOUR questions on YouTube. In this Q&A session we will answer your electrochemistry research questions LIVE, as well as any other questions related personal topics like careers, academia, industry, or life in general. We have compiled a database of all questions asked in our Ask Us Anything About Electrochemistry Livestreams, tagged by the question subject and linked with time stamps to the place in that week's Livestream. If you are interested in obtaining a copy of this database (MS Excel file), please reach out via comments here or directly to us at [email protected]. Check out https://aftermathlive.com, Pine Research's online electrochemical simulation software! Perfect for the classroom or research lab, licenses are available for simulating CV and bulk electrolysis of a variety of chemical and electrochemical reactions. Accessible on both PC and Mac! Time stamps: 00:00 - Introduction 06:00 - Livestream starts 15:05 - How can I tell if my electrolyte is getting contaminated? Is there a way to quantify the amount of contamination? 21:53 - I ran potentiostatic EIS using blocking electrodes and got a resistance of 1.54 ohms. However, when I used symmetric sodium electrodes instead, the resistance was 12,000 ohms. What could be causing this? 32:46 - In a GCD experiment, while testing with 3 electrodes I get high discharge time, but with 2 electrodes the entire experiment is over within 5 seconds. I am using carbon cloth as substrate. Why is this happening? 39:25 - An old 1950s research paper had electrolyte conductivity measurements listed. Were researchers using potentiostats with EIS back then, or is there another way they measured conductivity? 46:26 - Understanding EIS circuit fitting 56:55 - Is there a visual comparison between an EIS spectrum and a CV curve? Specifically, can the semicircle behavior or diffusion be related to CV behavior? 1:02:06 - How exactly do I make use of CV? Do I just get the E0 value? 1:06:50 - With my symmetric sodium cell, what is the likelihood of the SEI being unstable leading to high resistance? 1:10:00 - Can you describe the Daniell galvanic cell? 1:16:49 - What is a fun lab story where CV helped you learn something about an unknown system? 1:23:20 - When we perform CV, sometimes we get 1 redox peak and sometimes we get more. What is the scientific reason behind this? 1:26:58 - When I use one brand of potentiostat/software my CV looks differently from a different brand, why are they different? 1:33:07 - What are differences between CV, GCD, and EIS? 1:35:14 - How can we say our material will work in a battery with the help of CV? 1:39:42 - What are some of the fundamental chemistry equations related to thermodynamics and equilibrium? 1:46:15 - How do we set the potential window for different materials used as cathodes in energy storage devices? What factors affect it? 1:49:57 - In supercapacitors and batteries, if the operating window of a CV is in negative potentials, does this indicate the material is suitable as an anode?
