Research question
Can interfaces in low-cost zirconium-based halide composites provide faster ion transport while improving compatibility with other battery components?
Key result
Oxide–halide nanocomposites increased lithium-ion conductivity from 0.40 to 1.3 mS cm⁻¹ at 30 °C. Oxygen substitution at the interfaces explained the enhancement; fluorination also improved high-voltage and interfacial stability.
Research contribution
Jae-Seung Kim and Dong-Hwa Seo performed the theoretical calculations that explained enhanced interfacial transport. The calculations complemented synthesis, spectroscopy and cell testing by the collaborating teams.
