Editor’s note: This briefing was written in a joint collaboration between Admiral Instruments and Zahner Scientific Instruments. Admiral Instruments will be exhibiting (booth 400) at the 232nd ECS Meeting in National Harbor this fall. See a list of all our exhibitors. Problem Methods combining EIS with charge-discharge cycles are among the most powerful tools available to collect in-situ information about electrochemical systems such as battery cells and stacks. However, accurately measuring the rapidly-changing states of the electrodes, electrolytes, and other…

ECS Transactions 77(11) “Selected Proceedings from the 231st ECS Meeting: New Orleans, LA – Spring 2017,” has just been published. This issue contains papers from the following symposia: A01 – Battery and Energy Technology Joint General Session A02 – Large-Scale Energy Storage 8 A04 – Battery Safety A05 – Lithium-Ion Batteries and Beyond A06 – Battery Student Slam 1 B01 – Carbon Nanostructures for Energy Conversion B02 – Carbon Nanostructures in Medicine and Biology B04 – Endofullerenes and Carbon Nanocapsules
In May 2017 during the 231st ECS Meeting, we sat down with Eric Wachsman, director and William L. Crentz Centennial Chair in Energy Research at the University of Maryland Energy Research Center. The conversation is led by Rob Gerth, ECS’s director of marketing and communications. Wachsman is an expert in solid oxide fuel cells and other energy storage technologies. He’s the lead organizer of the 7th International Electrochemical Energy Summit, which will take place at the 232nd ECS Meeting in…

In May 2017 during the 231st ECS Meeting, we sat down with 2016-2017 ECS Toyota Young Investigator Fellowship winner, Elizabeth Biddinger, to discuss green chemistry, sustainable engineering, and the future of transportation. The conversation was led by Amanda Staller, ECS’s web content specialist. Biddinger is an assistant professor at the City College of New York, part of the City University of New York system. There, she leads a research group that covers research areas ranging from electrocatalysis to ionic liquids….

Lithium-ion batteries power a vast majority of the world’s portable electronics, from smartphones to laptops. A standard lithium-ion batteries utilizes a liquid as the electrolyte between two electrodes. However, the liquid electrolyte has the potential to lead to safety hazards. Researchers from MIT believe that by using a solid electrolyte, lithium-ion batteries could be safer and able to store more energy. However, most research in the area of all-solid-state lithium-ion batteries has faced significant barriers. According to the team from…

Instead of batteries, a new cell phone harvests the few microwatts of power it needs from a different source: ambient radio signals or light. Researchers were also able to make Skype calls using the battery-free phone, demonstrating that the prototype—made of commercial, off-the-shelf components—can receive and transmit speech and communicate with a base station. “We’ve built what we believe is the first functioning cell phone that consumes almost zero power,” says Shyam Gollakota, an associate professor of computer science &…
