Cement-based solid electrolyte, preparation method thereof and structural supercapacitor
The invention discloses a cement-based solid electrolyte, a preparation method thereof and a structural supercapacitor. The preparation method of the cement-based solid electrolyte comprises the following steps: mixing cement, a polymer, alkali, a redox additive and water to obtain mixed slurry; and placing the mixed slurry in a mold for hardening molding, and then performing maintenance to obtain the cement-based solid electrolyte, wherein the oxidation reduction additive is selected from at least one of 1-butyl-3-methylimidazole bromide, 1-butyl-3-methylimidazole chloride or 1-butyl-3-methylimidazole iodide. The preparation method comprises the following steps: adding the oxidation reduction additive into a reaction kettle; according to the cement-based solid electrolyte and the preparation method thereof, the redox additive is introduced, so that pores with uniform pore diameters are formed in the hydration process of the cement, the proper porosity is achieved, the number of conductive ions is also increased, and the supercapacitor prepared from the cement-based solid electrolyte has high electronic conductivity and excellent electrochemical performance.
本发明公开了一种水泥基固态电解质及其制备方法、结构超级电容器。所述水泥基固态电解质的制备方法包括以下步骤：将水泥、聚合物、碱、氧化还原添加剂和水混合得到混合浆料；将所述混合浆料置于模具中硬化成型，然后再进行养护，得到所述水泥基固态电解质；其中，所述氧化还原添加剂选自1‑丁基‑3‑甲基咪唑溴化物、1‑丁基‑3‑甲基咪唑氯化物或1‑丁基‑3‑甲基咪唑碘化物中的至少一种。本发明通过引入氧化还原添加剂使得水泥在水化的过程中形成孔径均匀的孔隙，达到适合的孔隙率，并且还增加了导电离子的数目，进而采用水泥基固态电解质制备的超级电容器具有高电子导电率以及优异的电化学性能。
