本文提出了一种具有“混合导体电极/快离子导体(或快离子导体粉体与炭质极化电极颗粒混合体)/混合导体电极”结构的离子注入型超大容量固体离子电容器.其电容量除由界面双电层形成外,研究还发现电容量随混合导体电极用量增加线性增大.研究采用Cu~(+)离子导体为固体电解质,Cu_2Mo_6S_7.7为混合导体电极.其容量密度高达50F/Cm~3,等效串联电阻(ESR)为40Ω,漏电流为15μA,分解电位为600mV.

In this paper, an ion implantation type large capacity solid capacitor with the structure of “mixed conductor electrode / fast ion conductor (or mixture of fast ion conductor powder and carbonaceous polarization electrode particle) / mixed conductor electrode” is proposed. Its capacitance In addition to the formation of the interface electric double layer, the study also found that the capacitance increases linearly with the amount of mixed conductor electrode.Using Cu ~ (+) as the solid electrolyte and Cu_2Mo_6S_7.7 as the mixed conductor electrode, the capacity density is as high as 50F / Cm ~ 3, the equivalent series resistance (ESR) is 40Ω, the leakage current is 15μA, and the decomposition potential is 600mV.
