中科院物构所胡翔最新AM丨双阳离子电解液重构溶剂化结构实现万圈长寿命钠硫电池！

TL;DR - An Advanced Materials study introduces a Na⁺/K⁺ dual-cation electrolyte that improves sulfur conversion and sodium-metal stability in room-temperature sodium–sulfur batteries. The resulting full cell retained 95.3% capacity after 10,000 cycles at 10 A g⁻¹.

• K⁺ restructures Na⁺ solvation into contact-ion-pair-rich shells, suppressing polysulfide dissolution and promoting an inorganic-rich SEI.
• Mixed NaKSₓ intermediates delocalize charge, weaken sulfur-related bonds, and lower sulfur-conversion barriers.
• Electrostatic shielding and a CHMCN electrode architecture promote uniform Na⁺ deposition and inhibit dendrites.
• A pouch cell achieved a reported energy density of 223 Wh kg⁻¹.
