摘　　要：对超级电容器用活性炭中钾离子的脱除工艺方法进行了研究。实验中,通过氧化处理、加热反应和超声洗涤等处理过程,将活性炭中的钾离子含量从3 000×10-6脱除到50×10-6以下。处理后的活性炭具有高纯度、低钾含量、低灰分等优点;使用时,不会发生电碱金属还原析出所引起的短路故障,保证了电容器自身放电的最低度,延长了储电产品寿命。A removal process of potassium in a kind of activated carbon for supercapacitor are studied. In this experiments, by means of oxidation treatment, heating reaction, and ultrasonic washing treatment, the potassium ion content in the activated carbon removal from 3 000 x 10 -6 to 50 x 10 -6 or less. Treated acti- vated carbon has the advantages of high - purity, low potassium content and low ash ; so it avoid electrical- ly alkali metal reduction precipitation caused by a short circuit fault, to ensure minimum discharge of the capacitor itself, extend the product life of the electricity storage.
