Tools for Assessing Cost and Environmental Impacts of End-of-Life Management of Sodium Batteries

Aravind Baby, Qiang Dai, Jeffrey S. Spangenberger

Sodium-ion batteries (SIBs) are increasingly being viewed as viable alternatives for lithium-ion batteries (LIBs), especially for large-scale energy storage, as they decrease the U.S. dependence on critical materials. SIBs use less expensive raw materials while improving operational safety. The geographic distribution of …

Monitoring Surface-Enhanced Infrared Absorption Spectroscopy on a Graphitic Electrode for in-Situ Surface-Sensitive Electrochemistry: Designing Electrode Interfaces for Carbon Capture

A.S. Siddiqui, Jeanne N’Diaye, Kristin E. Martin, Aravind Baby et autres

Combining spectroscopy with electrochemistry enables the monitoring of changes in bonding, molecular orientation, and chemical composition during electrochemical processes at the electrode/electrolyte interface. Surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) allows a direct in situ monitoring of electrochemical processes occurring at the electrode interface …

A simple room-temperature refurbishment method for sulfated lead-acid batteries using ammonium acetate treatment

Aravind Baby, Abdelilah Asserghine, Elizabeth J. Gao, Huimin Zhao et autres

Current recycling paradigms of lead-acid batteries (LABs) involve the use of toxic, polluting, and energy-demanding processes. Here we report a novel strategy to refurbish LABs which failed due to the formation of hard sulfation on the anodes. We used ammonium acetate (NH …

Monitoring SEIRAS on a Graphitic Electrode for Surface-Sensitive Electrochemistry: Real-Time Electrografting

A.S. Siddiqui, Jeanne N’Diaye, Kristin E. Martin, Aravind Baby et autres

The ubiquity of graphitic materials in electrochemistry makes it highly desirable to probe their interfacial behavior under electrochemical control. Probing the dynamics of molecules at the electrode/electrolyte interface is possible through spectroelectrochemical approaches involving surface-enhanced infrared absorption spectroscopy (SEIRAS). Usually, this technique …
