• Nano-dispersed SnS₂ and CoS₂ phases endow CSC anode with electrolyte/structure-dependent cocktail mediation effect, showing superior rate capability and evidently lowered charge plateau compared with CoS₂ and SnS₂/CoS₂ mixture.

• Alternative electrochemical processes between nano-dispersed different metal sulfides and Na⁺ carriers effectively overcome intrinsic flaws of monometallic sulfide, responsible for the lowered charge plateau of CSC.

• As-assembled CSC//Na_1.5VPO_4.8F_0.7 full-cell shows high-rate capability, and high discharge plateau up to 2.57 V, which is comparable to that with alloy-type anodes.

电解质/结构相关的鸡尾酒调解使高速率/低高原金属硫化物阳极能够储存钠

• _{与 CoS 2}和 SnS ₂ /CoS ₂混合物相比，纳米分散的 SnS ₂和 CoS ₂相赋予 CSC 负极电解质/结构依赖的鸡尾酒中介效应，表现出优异的倍率性能和明显降低的充电平台。

• 纳米分散的不同金属硫化物和 Na ⁺载体之间的替代电化学过程有效地克服了单金属硫化物的内在缺陷，导致 CSC 的电荷平台降低。

• 组装后的 CSC//Na _1.5 VPO _4.8 F _0.7全电池表现出高倍率能力和高达 2.57 V 的高放电平台，这与合金型阳极相当。
