发明名称 All-solid-state capacitor
摘要 An all-solid-state capacitor includes an inorganic solid electrolyte; and a pair of current collectors disposed so as to hold it in between. The inorganic solid electrolyte has a polycrystalline structure, and the all-solid-state capacitor satisfies a relationship given as: R1<R2<R3, a relationship given as: C1<C3, and a relationship given as: C1<C2 in which, R1, R2 and R3 are resistance components, and R1 denotes an intragrain resistance of the inorganic solid electrolyte, R2 denotes a grain-boundary resistance of the inorganic solid electrolyte and R3 denotes an interfacial resistance between the inorganic solid electrolyte and the current collector, and, C1, C2 and C3 are capacitance components, and C1 denotes an intragrain capacity of the inorganic solid electrolyte, C2 denotes a grain-boundary capacity of the inorganic solid electrolyte and C3 denotes an interfacial capacity between the inorganic solid electrolyte and the current collector.
