摘要:本文選擇以玉米桿為模板制備多孔的錳氧化物，將玉米桿在烤箱里烘干后研磨，用Mn(NO3)2和MnAc2和10ml水配備錳液，并將其浸泡玉米桿24h，用相同的方法制備四個(gè)樣品，然后都將其放在坩堝里再在馬弗爐里焙燒，溫度都調(diào)至200℃燃燒30min，再分別轉(zhuǎn)移到200℃、400℃、600℃、800℃的馬弗爐里焙燒90min，分別取出樣品，進(jìn)行編號(hào)，將樣品在NMP、N一甲基毗咯烷，PVDF 、聚偏氟乙烯，碳黑下進(jìn)行研磨，磨的時(shí)間15-20min，然后在銅箔上制做膜片，再把膜片放在干燥箱中干燥，用三相異步電動(dòng)機(jī)進(jìn)行切片，把極片切成10個(gè)孔徑為16mm的小圓片裝于小袋中。配置0.5摩爾每升的硫酸鉀溶液浸泡隔離膜和膜片，裝電容器；利用玉米稈作為模板，制備多孔錳氧化物，并將其作為電極材料做電性能的研究，將模板法延伸到利用生活中的基本植物作為模板，已達(dá)到對(duì)資源合理利用。從實(shí)驗(yàn)結(jié)果分析可得如下結(jié)論： （1）圖表對(duì)比結(jié)果表明各曲線相對(duì)較平穩(wěn)，沒有太大的起伏波動(dòng)，說明電性能循環(huán)較穩(wěn)定。隨焙燒溫度的升高衰減率逐漸下降，當(dāng)樣品在200oC的馬弗爐里焙燒30min然后再轉(zhuǎn)移到400oC的馬弗爐里焙燒90min的條件下，曲線最為平穩(wěn)，衰減率最為理想，循環(huán)性能較好； （2）綜合分析可知道，溫度對(duì)充放電性能的影響較小，而樣品焙燒在200oC的馬弗爐里焙燒30min然后再轉(zhuǎn)移到600 oC的馬弗爐里焙燒90min為最佳狀態(tài)； 關(guān)鍵詞：玉米桿；錳氧化物；電性能測(cè)試；模板
Abstract:This article chooses to corn rod for preparation of porous manganese oxide template, corn lever in the oven drying with Mn (after grinding, MnAc2 and NO3 -) 2 and 10ml water equipped with manganese liquid, and its immersion corn stem 24h, in the same way, and then all four sample preparation put it in the crucible muffle furnace again in the roasting, temperatures are transferred to 200 ℃ respectively, burning 30min again ℃ and 400 transfer to 200 ℃, 600 ℃, 800 ℃ in the roasting 90min muffle furnace, respectively, Numbers, take samples in the sample NMP, N a methyl methoxyflurane, PVDF, pelatiah luo PVDF, carbon black, mill grind under 15-20min, then time in copper foil on the diaphragm, again making diaphragm in drying oven drying, use of three-phase asynchronous motor for a slice, slices into 10 aperture for 16mm little discs installed in a small bag. Configuration 0.5 per litre Moore，Use YuMiGan as templates, preparation of porous manganese oxide, and as the electrode material, will do performance extends templates by the basic plant life as templates, has reached the rational utilization of resources. From the analysis of experimental results can get a conclusion that: (1) chart compares results show that each relatively smoothly, not curves of too big a fitful, explain performance circulation is stable. The calcination temperature rise with attenuation gradually declined, when sample in the muffle furnace in 200oC 30min then transferred to the roasting in the 400oC muffle furnace 90min roasting, under the condition of most smoothly, attenuation curve most ideal, circulation performance is better; (2) comprehensive analysis can know, temperature on filling Keywords: Manganese oxide; E-test; Template |
