Techno-Economic Modeling -- Building New Battery Systems on the Computer
JCESR is applying techno-economic models to project the performance and cost of a wide array of promising new battery systems before they are prototyped. The results from techno-economic modeling establish performance “floors” for discovery science teams looking for new anodes, cathodes, and electrolytes for a beyond lithium-ion battery, identifying those with the potential to meet JCESR’s goal and rejecting those unlikely to be effective.

Promising Directions and the Tools to Get Us There
At the halfway point in our five-year charter, we have narrowed our research directions within the three promising energy storage concepts we are pursuing: multivalent intercalation, chemical transformation, non-aqueous redox flow. In converging these directions to proof-of-concept prototypes, we make extensive use of JCESR’s distinguishing tools. Read More

Coupled Cation-Anion Dynamics Enhances Cation Mobility in Room Temperature Superionic Solid-State Electrolytes
Our work reveals facile [PX4]3- anion rotation in superionic Na11Sn2PS12 and Na11Sn2PSe12, and greatly hindered [SbS4]3- rotational dynamics in their less conductive analogue, Na11Sn2SbS12. Along with introducing dynamic frustration in the energy landscape, the fluctuation caused by [PX4]3- anion rotation is firmly proved to couple … Read More
