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.

Li+ hopping mechanism in LiTFSI water-in-salt electrolyte identified by molecular dynamics simulations
The high Li+ apparent transference number in the LiTFSI water-in-salt electrolyte was captured by MD simulations and the dominant Li+ conduction mechanism in the highly concentrated LiTFSI water-in-salt electrolyte was identified to be hopping between water and TFSI- anions. Read More

High-Efficiency Zinc-Metal Anode Enabled by Liquefied Gas Electrolytes
A liquefied gas electrolyte was developed for the 1st time for a bivalent chemistry. It displays an excellent Zn conductivity (>3.4 mS cm-1) across a broad temperature range (-60 to +20 °C), enables highly reversible Zn cycling with no evidence of shorting behavior at both … Read More

Limited Accessibility to Surface Area Generated by Thermal Pretreatment of Electrodes Reduces Its Impact on Redox Flow Battery Performance
A systematic study on thermally pretreated electrodes for redox flow batteries (RFBs) leveraging gas adsorption techniques, physicochemical spectroscopy, in situ flow cells, and a convection-reaction model suggests diminishing returns in RFB performance at longer pretreatment times due to hindered active species transport to recessed regions … Read More

First-principles calculations predict Ca cathodes based on layered calcium transition metal oxide materials
First-principles calculations are used to demonstrate that P-type layered CaTM2O4 materials with a range of TM substitutions (TM = Ti, V, Cr, Mn, Fe, Co, and Ni) have excellent battery-related properties including thermodynamic stability, average voltage, energy density, synthesizability, ionic mobility, and electronic structure.
