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.

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
