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！
Merged summary
TL;DR — 该 Advanced Materials 研究通过 Na⁺/K⁺ 双阳离子电解液重构溶剂化结构，同时改善硫转化动力学与钠金属稳定性，使室温钠硫电池在 10 A g⁻¹ 下循环 10,000 次后仍保持 95.3% 容量。
- K⁺促使 Na⁺形成富接触离子对的溶剂化壳层，抑制多硫化物溶解并构筑无机组分丰富的 SEI。
- 混合 NaKSₓ 中间体通过电荷离域削弱硫相关化学键，降低硫转化能垒。
- 静电屏蔽效应结合 CHMCN 电极结构促进 Na⁺均匀沉积并抑制枝晶。
- 该体系的软包电池实现了 223 Wh kg⁻¹ 的报告能量密度。
注：第二则来源实际描述 Co–Gd 双单原子催化的 Li–O₂ 电池研究，与标题所指钠硫电池工作并非同一研究，因此未合并其技术与性能数据。

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.

TL;DR - An Advanced Materials study introduces a Co–Gd dual-single-atom catalyst that directs oxygen-species spillover between adjacent sites, bypassing linear adsorption-scaling constraints in Li–O₂ batteries. This spatially decoupled catalysis reduces polarization and improves efficiency and cycling stability.
- Gd sites activate O₂ and capture LiO₂, while neighboring Co sites drive subsequent lithiation, decomposition, and desorption.
- Theory, spectroscopy, EIS/DRT, in situ UV–vis, and DEMS support directed LiO₂ migration from Gd to Co.
- CoGd-DAC achieved a 0.463 V polarization gap, 87% energy efficiency, and more than 310 stable cycles.
- The approach shifts catalyst design from single-site adsorption control toward migration-controlled, spatially cascaded reactions.
