A novel aqueous/aprotic electrolyte with low salt concentration (i.e., 0.5 m Zn(CF₃SO₃)₂+1 m LiTFSI) demonstrated an expanded electrochemical window, which can simultaneously stabilize Zn metal anode and increase the operation voltage of Zn-ion hybrid supercapacitors.

The coordination shell of the electrolyte induced by acetonitrile and LiTFSI can not only suppress the Zn corrosion and hydrogen evolution reaction but also promote the cathodic stability and ion migration, which is depicted by the density functional theory simulations together with experimental characterizations.

The Zn-ion hybrid supercapacitor based on the developed electrolyte can operate within 0–2.2 V in a wide temperature range with an ultra-long lifespan (> 120,000 cycles).

一种新型的低盐浓度水/非质子电解质（即0.5 m Zn(CF ₃ SO ₃ ) ₂ +1 m LiTFSI）表现出扩大的电化学窗口，可以同时稳定锌金属阳极并提高锌离子的工作电压混合超级电容器。

密度泛函理论模拟和实验表征表明，乙腈和LiTFSI诱导的电解质配位壳不仅可以抑制Zn腐蚀和析氢反应，还可以促进阴极稳定性和离子迁移。

基于所开发的电解质的锌离子混合超级电容器可以在0-2.2V的宽温度范围内工作，并具有超长的寿命（>120,000次循环）。
