High-Throughput Computational Screening of Quinones for Electrochemical CO2 Capture

Abstract Electrochemical carbon capture (ECC) with quinones is a promising, energy-efficient alternative to thermal systems, but oxygen sensitivity remains a significant challenge. The persistent trade-off between CO2 affinity (KCO2) and reduction potentials (Ered) requires ident...

Cathode vs Electrolyte: Decoupling the Origins of Degradation in High-Voltage Ni-Rich Lithium-Ion

Abstract Raising the upper cutoff voltage and deploying Ni-rich layered oxides (e.g., NMC811) are promising routes to higher lithium-ion cell energy density. However, the origin of degradation remains unclear at high-voltage operation. We propose using a cycle-relevant scan rate...
