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.

ZnNixMnxCo2–2xO4 Spinel as a High-Capacity Cathode Material for Nonaqueous Zn-Ion Batteries
A new series of spinels, ZnNixMnxCo2-2xO4, are reported as a high-voltage and high-capacity cathode material for non-aqueous Zn-ion batteries. Mn, Ni co-substitution for Co in ZnCo2O4 is demonstrated to be an efficient method to facilitate Zn-deintercalation and enhance discharge capacity, which provides guidelines for designing … Read More

Tailored Reaction Route by Micropore Confinement for Li-S Batteries under Lean Electrolyte Conditions
Li2S2 is experimentally verified by ex-situ S K‐edge X‐ray absorption spectroscopy to be stable in the micropores during discharging in Li-S cells. A new reversible electrochemical pathway is thus proposed, based on the inherent self‐healing capacity for Li2S2, under lean electrolyte conditions. Read More

Reaction Pathways for Solvent Decomposition on Magnesium Anodes
Dimethoxyethane (DME) is predicted to rapidly decompose to ethylene gas and other products on the metallic Mg surface, whereas the presence of an oxide or chloride surface film on a Mg anode is predicted to limit solvent decomposition. Read More
