Abstract Electrophoretic deposition（ EPD） refers to the colloidal solution in the voltage applied to the electrodes, the electrode toward the surface of the colloidal particles deposited layer formed by the discharge process. β 23l?? the sodium ion conductivity higher than β 23l??, β phase, the higher the purity, the better electrical properties, which makes it in the energy sector has important applications. In this study, β 23l??solid electrolyte structure to a pound by a dense layer and a porous substrate layer, a porous substrate to allow free passage of sodium ions, the actual resistance depends dense β 23l??layers. This experiment to βAl2O3 powder and 1% TiO2 doped of βAl2O3 powder as a raw material, namyl alcohol as the solvent as dispersant triethanolamine stearate, aluminum pore porous layer, EPD method βAl2O3 posite electrolyte. Composite electrolyte layer and a porous layer of dense structure, by this experiment that: the deposition voltage of 200V and a deposition time of 300S, TEA is added in an amount βAl2O3 powder, 10% by mass, the crystallization and the dense layer, uniform particle size, high density。 本研究將 β 23l??固體電解質(zhì)結(jié)構(gòu)改為復(fù)合式 ， 由 致密 層和 多孔 基體層組成 ， 多孔基體允許鈉離子自由通過，實(shí)際電阻取決于致密 β 23l??層。 β 23l??的 鈉離子電導(dǎo)率遠(yuǎn)高于 β 23l??， β相的純度越高，電性能越好，這使得它 在能源領(lǐng)域中有重要應(yīng)用 。由于鈉離子可以在多孔層空隙中穿過，由致 密層與多孔層形成的復(fù)合電解質(zhì)相對(duì)于單一的致密層有著較高的電導(dǎo)率 ，且 βAl2O3復(fù)合電解質(zhì) 的電導(dǎo)率隨著加熱溫度的升高而提高，材料的活化能為 。 solid electrolyte南京工業(yè)大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） i 目錄 摘要 ...............................................................................................................................I Abstract .......................................................................................................................
