【摘要】：本論文采用一步模板電沉積法制備了能用于柔性全固態(tài)對稱超級電容器的活性電極材料,其中包括聚苯胺、二氧化錳和聚噻吩。此外,利用掃描電子顯微鏡(SEM)對材料的形貌進(jìn)行了觀察。同時利用傅里葉變換紅外光譜(FT-IR)、X射線衍射(XRD)和X射線光電子能譜(XPS)等對材料的結(jié)構(gòu)和組成進(jìn)行了表征。之后研究了這些材料的電化學(xué)性能。本論文主要研究內(nèi)容如下:1.采用一種簡易的模板電沉積方法制備了PANI有序納米管陣列膜電極。在該方法中,PANI納米管通過循環(huán)伏安法沉積在Au/PC膜中。使用PVA/H2SO4作為固態(tài)凝膠電解質(zhì),所獲得的PANI納米管陣列膜可以直接用作柔性全固態(tài)超電容器的電極。制備的超級電容器可以達(dá)到237.5mF cm-2的最大面積比電容。在電流密度為1.0 mA cm-2的條件下經(jīng)過2000個循環(huán),仍保持初始電容值的95.2%,這顯示其優(yōu)異的循環(huán)穩(wěn)定性。除此之外,所制備的超級電容器能夠成功點亮LED燈,證明了其潛在的實際應(yīng)用價值。2.通過簡單的電沉積方法成功獲得了MnO_2多孔納米線。所獲得的基于MnO_2多孔納米線的薄膜用作電極材料,用PVA/LiCl作粘合劑和固態(tài)電解質(zhì)以構(gòu)建超級電容器,其面積比電容可以達(dá)到44.6 mF cm-2。該超級電容器同時表現(xiàn)出了優(yōu)異的柔性和良好的穩(wěn)定性,而且可以點亮LED燈。這些結(jié)果表明,基于MnO_2多孔納米線的柔性電極對于在高性能超級電容器器件中的應(yīng)用是非常有前景的。3.通過一步電沉積方法制備了用不同的酸介質(zhì)和表面活性劑摻雜的PEDOT納米管.所構(gòu)建的超級電容器面積比電容可達(dá)到113.5 mF cm-2。在2000次循環(huán)后,其電容值幾乎保持初始電容值的95.5%,顯示出了優(yōu)異的循環(huán)穩(wěn)定性。制備出來的柔性全固態(tài)超級電容器可以點亮LED燈,以用來滿足微電源的實際應(yīng)用。憑借顯著的性能,該設(shè)備可以成為柔性和便攜式/可穿戴電子設(shè)備能量存儲系統(tǒng)的最有前景的候選者之一。
[Abstract]:In this paper, active electrode materials, including Polyaniline, manganese dioxide and polythiophene, were prepared by one-step template electrodeposition for flexible all-solid-state symmetric supercapacitors. In addition, the morphology of the material was observed by scanning electron microscope (SEM). The structure and composition of the materials were characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrochemical properties of these materials were studied. The main contents of this thesis are as follows: 1. The PANI ordered nanotube array membrane electrode was prepared by a simple template electrodeposition method. In this method, pani nanotubes were deposited in Au/PC films by cyclic voltammetry. Using PVA/H2SO4 as solid gel electrolyte, the PANI nanotube array film can be directly used as electrode for flexible all-solid supercapacitor. The prepared supercapacitor can reach the maximum area specific capacitance of 237.5mF cm-2. When the current density is 1. 0 Ma cm-2, the initial capacitance is kept at 95.2% after 2 000 cycles, which shows its excellent cycle stability. In addition, the supercapacitor can successfully illuminate the LED lamp, which proves its potential practical application value. 2. MnO_2 porous nanowires were successfully obtained by simple electrodeposition. The thin films based on MnO_2 porous nanowires were used as electrode materials, and PVA/LiCl was used as binder and solid electrolyte to construct supercapacitors. The area specific capacitance of the supercapacitors was up to 44.6 mF cm-2. The supercapacitor also shows excellent flexibility and stability, and can light up the LED lamp. These results show that the flexible electrode based on MnO_2 porous nanowires is very promising for its application in high performance supercapacitor devices. PEDOT nanotubes doped with different acid media and surfactants were prepared by one step electrodeposition. The area specific capacitance of the supercapacitor can reach 113.5 mF cm-2. After 2000 cycles, the capacitance value is almost 95.5% of the initial capacitance value, showing excellent cycle stability. The flexible all-solid-state supercapacitor can light up the LED lamp to meet the practical application of micro-power supply. With significant performance, the device can be one of the most promising candidates for flexible and portable / wearable electronic devices energy storage systems.
