摘要:本文以錳酸鹽作為電化學(xué)電容器的電極材料，系統(tǒng)研究不同的燃燒時(shí)間，錳氧化物的電化學(xué)性能為工作目的，多種現(xiàn)代物理測(cè)試手段和電化學(xué)研究方法研究了材料制備、電容特性及其影響因素、電容形成機(jī)理。恒流充放電、循環(huán)伏安等實(shí)驗(yàn)顯示了由錳氧化物組裝的電容器具有較好的電化學(xué)性能。 利用液相燃燒法用相應(yīng)試劑制備出產(chǎn)物，并測(cè)其電化學(xué)性能，用醋酸和硝酸為原料，首先材料合成用()2 + (3)2 =1:1混合，再加10ml（約占總體積的20%）水配制成錳液，然后將配制好的錳液取適量溶液在坩堝中，按照不同的條件要求，將坩堝放入馬弗爐中加熱（固定溫度400℃），記錄加熱過(guò)程中所發(fā)生的變化，時(shí)間分別為10min、30min、1h、3h和6h，在焙燒完成以后，取出所得到的產(chǎn)物（、、）等表征產(chǎn)物的電化學(xué)性能 ，最后在電池測(cè)試系統(tǒng)上測(cè)其電性能，并分析電性能。 系統(tǒng)研究了錳氧化物電化學(xué)電容器組的組裝方式對(duì)其電化學(xué)性能的影響。 關(guān)鍵詞：電化學(xué)電容器；電極材料；錳氧化物
Abstract:In this paper, permanganate as electrode materials for electrochemical capacitors, the burning time of different systems, the electrochemical properties of manganese oxide as the working end, a variety of modern methods of physical tests and electrochemical methods of material preparation, characteristics and capacitance its impact factor, capacitor formation mechanism. Constant current charge-discharge, cyclic voltammeter experiments show the assembly of the manganese oxide capacitor has a good electrochemical performance. The use of liquid combustion products prepared with the appropriate reagents, and measured the electrochemical properties, with acetic acid and nitric acid as raw materials, the first synthesis using ()2 + (3)2 = 1:1 mixed with 10ml (about 20% of the total volume) of water into the preparation of manganese solution, and then prepared to take a good amount of liquid solution of manganese in a crucible, in accordance with the requirements of different conditions, place the crucible in the muffle furnace heating (constant temperature of 400℃) recorded in the heating process changes, the time was 10min, 30min, 1h, 3h and 6h, the roasting is complete, remove the resulting products (,,etc.) characterization of electrochemical properties of the product, in the end battery test system, test its electrical properties, and analysis of electrical properties.
