Energy Storage Emerging
Instead of trying to find battery chemistries specifically tailored to particular technological needs, JCESR researchers have traded a “top-down” process for a ”bottom-up” approach in which they focus on fundamental investigations of different chemical processes on the atomic and molecular levels. “The idea is … Read More

Technology
JCESR’s focus has changed to building transformational materials from the bottom up, atom-by-atom and molecule-by-molecule, where each atom or molecule plays a prescribed role in producing the desired overall materials performance. We could not have done this 10 years ago when the advanced scientific tools … Read More

Team Approach
JCESR is a collaborative team of engineers and scientists with very broad backgrounds. In the battery space we are now facing challenges that required a multidisciplinary approach that no single group can achieve. Made up of 18 partner institutions, JCESR’s diversity and the opportunity for … Read More

Untapped Potential: The Need and Opportunity for High-Voltage Aqueous Redox Flow Batteries
Prior studies of the techno-economic design space for aqueous redox flow batteries (AqRFBs) have almost exclusively focused on cell potentials ≤1.5 V, due, at least in part, to the belief that battery operation at higher cell potentials in not feasible due to electrolyte decomposition. However, … Read More
