Topological Design of Highly Conductive Weakly Solvating Electrolytes for Ultrastable Sodium Metal Batteries Operating at −60 °C and Below

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

Weakly solvating electrolytes (WSE) can favor reversible Na batteries at -40 °C for some extreme applications because of the low desolvation energy. However, it is challenging to enable lower temperatures. Herein, we uncover that ionic conductivity WSE reduces reaction kinetics -60 °C. Accordingly, a highly conductive weakly electrolyte (HCWSE) designed by introducing additives strongly solvents and dilution NaPF6. The additive dominate solvation sheath, increase dissociation NaPF6 fluidity electrolyte, thus greatly improve conductivity. Furthermore, binding energy between Na+ proposed as descriptor determine power solvents, based on which series ultralow-temperature HCWSEs have been topologically facilely strong-solvation ether into weak-solvation solvents. As demonstration, HCWSE showcases long cycling Na||Na cell with an overpotential 42 mV under 1 mA cm-2 1200 h. Na||NNFM (Na0.75Ni0.25Fe0.25Mn0.5O2) exhibits capacity 79.2 mAh g-1 after 160 cycles. cells also achieve impressive performances -70
