【摘要】：為了減少化石燃料消耗和溫室氣體排放,使用可再生能源的電力生產(chǎn)是實現(xiàn)可持續(xù)發(fā)展的一個重要方法。鋰離子電池與超級電容器在新能源中具有很重要位置,它們能使能量存儲與處理更加有效與便捷。相對于鋰離子電池,超級電容器具有相對較高的功率密度。從電池材料方面來看,為了盡可能減少環(huán)境污染并提高材料工作效率,很多研究方向均關(guān)注在對環(huán)境更加無害并能高效利用的材料上,到目前為止,價格低廉的多孔炭材料是商業(yè)化最廣泛的電極材料。研究者們對其進(jìn)行了大量研究。在本論文中,首先從環(huán)保、對環(huán)境無害材料角度出發(fā),在氧化石墨表面聚合生成具有一定形貌的聚苯胺,經(jīng)冷凍干燥得到氧化石墨/聚苯胺(GO/PANI)復(fù)合材料,隨之進(jìn)行炭化,所得炭材料會保留之前聚苯胺骨架,從而具有一定形貌。通過表征觀察復(fù)合材料形貌,同時制作成電極片并組裝成超級電容器進(jìn)行電化學(xué)性能測試。同時從循環(huán)利用廢棄材料、保護(hù)環(huán)境資源角度出發(fā),研究廢棄材料——濾水器的廢棄濾芯,看其是否具有作為超級電容器電極材料的能力,從而判斷是否有必要重新回收并利用廢棄濾水器濾芯。對廢棄濾芯進(jìn)行最簡單烘干處理之后進(jìn)行熱處理,隨之進(jìn)行活化處理得最終材料。表征得到最終材料的最基本信息之后制作成超級電容器電極并測試其電化學(xué)性能。分析結(jié)果顯示廢棄濾芯活化后的材料具有可觀的比電容,在電流密度為1A/g時比電容為122.8 F/g,同時具有相對穩(wěn)定的循環(huán)特性。在硫酸鈉體系中具有相對較高能量密度,達(dá)到32.9 Wh/kg,電化學(xué)性能表現(xiàn)優(yōu)異。
[Abstract]:In order to reduce fossil fuel consumption and greenhouse gas emissions, the use of renewable energy to generate electricity is an important way to achieve sustainable development. Lithium ion batteries and supercapacitors play an important role in new energy sources. They make energy storage and processing more efficient and convenient. Compared with lithium ion batteries, supercapacitors have relatively high power density. In order to minimize environmental pollution and improve the efficiency of materials, many research directions have focused on more environmentally sound and efficient materials, so far. Low cost porous carbon is the most widely commercial electrode material. Researchers have done a lot of research on it. In this paper, first of all, from the point of view of environmental protection, environmentally sound materials. Polyaniline with certain morphology was formed by polymerization on the surface of graphite oxide, and then the graphite oxide / Polyaniline oxide / Polyaniline (PO / PANI) composite was prepared by freeze-drying, and then carbonized. The obtained carbon material will retain the pre-Polyaniline skeleton and thus have a certain morphology. The morphology of the composite is observed by characterization. At the same time, the electrode sheet was made and the supercapacitor was assembled to test the electrochemical performance. At the same time, the waste filter core of water filter was studied from the perspective of recycling waste materials and protecting environmental resources. See if it has the ability to act as electrode material for supercapacitor, so as to determine whether it is necessary to recycle and use the waste water filter element. The waste filter is treated with the simplest drying and heat treatment. The final material was obtained by activation treatment. After the basic information of the final material was obtained, the supercapacitor electrode was prepared and its electrochemical performance was tested. The analysis results show that the activated material of the waste filter core has considerable properties. Specific capacitance. When the current density is 1 / g, the specific capacitance is 122.8 F / g and has a relatively stable cycling property. It has a relatively high energy density of 32.9 Wh/kg in sodium sulfate system. Excellent electrochemical performance.
