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

Direct Nano-Synthesis Methods Notably Benefit Mg-Battery Cathode Performance
A novel Mg cathode material – CuCo2S4 – was identified as a conversion material where direct nano-synthesis was required to provide the best electrochemical performance and deliver 350 mAh·g-1 at 60 °C, a capacity nearly double that of ball-milled material with similar dimensions. Read More

Quantifying Capacity Losses due to Solid Electrolyte Interphase Evolution
We quantified the capacity loss originating in solid electrolyte interphase (SEI) growth during each cycle and extracted the proportionality constant for SEI growth following a parabolic growth law. This continuous SEI growth contributes to the increasing overpotential, leading to capacity fading at a given constant … Read More

On Lifetime and Cost of Redox-Active Organics for Aqueous Flow Batteries
In this viewpoint, we recommend methodology for (1) testing aqueous organic flow batteries to better understand the fade mechanisms and failure modes, and for (2) techno-economic assessment of these batteries that incorporates the costs associated with electrolyte decay and replacement to articulate a feasible design … Read More
