電容(rong)的主要物理特(te)征是儲存電荷，像蓄電池一樣可以充(chong)電（charge）和放電（discharge），但不發生化學反應。

而(er)電池是把電能轉(zhuan)化(hua)為化(hua)學能儲存，再轉(zhuan)化(hua)為電能輸出。

如果要和電(dian)池相(xiang)比，那就要說(shuo)到超級電(dian)容。

超級電容的特點：

（1）充(chong)(chong)電速度(du)快，充(chong)(chong)電10秒～10分鐘可達到(dao)其(qi)額定容量的95%以(yi)上(shang)；

（2）循(xun)環(huan)使用壽命(ming)長，深度(du)充放電循(xun)環(huan)使用次(ci)(ci)數(shu)可達1~50萬次(ci)(ci)，沒有“記憶效(xiao)應”；

（3）大(da)電(dian)流(liu)放(fang)電(dian)能(neng)力，能(neng)量轉換，過程損(sun)失小，大(da)電(dian)流(liu)能(neng)量循環效率(lv)≥90%；

（4）功率密度高，可達300W/KG~5000W/KG，相當于電(dian)池的5~10倍；

（5）產品原材料構成、生產、使用、儲存(cun)以(yi)及拆解過程均沒有污染(ran)，是理想(xiang)的綠色環保(bao)電源；

（6）充放電線(xian)路簡單，無需(xu)充電電池那樣的充電電路，安全系(xi)數高(gao)，長期(qi)使用免維護；

（7）超低溫特性(xing)好，溫度范圍(wei)寬(kuan)-40℃～+70℃；

（8）檢測方便，剩余電量(liang)可直接(jie)讀出；

（9）容量范(fan)圍(wei)通常0.1F--1000F 。

這(zhe)(zhe)種壽命溫(wen)度(du)(du)依賴度(du)(du)實(shi)際(ji)影響了(le)您(nin)降低(di)電(dian)容(rong)器(qi)(qi)額(e)定電(dian)壓的(de)方法。您(nin)首先(xian)想到的(de)可能(neng)是增(zeng)加(jia)電(dian)容(rong)器(qi)(qi)額(e)定電(dian)壓來(lai)化電(dian)介質失效的(de)機率。但是，這(zhe)(zhe)樣做會使電(dian)容(rong)器(qi)(qi)的(de)等(deng)效串聯(lian)電(dian)阻 (ESR) 更高。由于(yu)電(dian)容(rong)器(qi)(qi)一般會具(ju)有高紋(wen)波電(dian)流(liu)應力(li)，因此這(zhe)(zhe)種高電(dian)阻會帶來(lai)額(e)外的(de)內部功耗(hao)，并且增(zeng)加(jia)電(dian)容(rong)器(qi)(qi)溫(wen)度(du)(du)。故障率隨溫(wen)度(du)(du)升高而增(zeng)加(jia)。實(shi)際(ji)上，鋁電(dian)解(jie)電(dian)容(rong)器(qi)(qi)通常只(zhi)使用其(qi)額(e)定電(dian)壓的(de) 80% 左右。

電(dian)容器溫度較低時，ESR 急劇增加，如圖 2 所示。在(zai)這種情況下，-40oC 下，電(dian)阻呈(cheng)數量(liang)級(ji)(ji)增加。這在(zai)許(xu)多方面都會影(ying)響到電(dian)源(yuan)性(xing)能。如果電(dian)容器用(yong)于開關式電(dian)源(yuan)的(de)輸(shu)出端(duan)，則輸(shu)出紋波電(dian)壓呈(cheng)數量(liang)級(ji)(ji)增加。另外，在(zai) ESR 和(he)輸(shu)出電(dian)容形成的(de)零以(yi)上頻(pin)率，它讓環路增益增加一個數量(liang)級(ji)(ji)，從而影(ying)響控制(zhi)環路。這會產(chan)生一個有振蕩的(de)不穩(wen)定電(dian)源(yuan)。為了適應這種強震動(dong)，控制(zhi)環路通常會在(zai)空(kong)間方面做出巨大(da)妥協，并在(zai)更(geng)高溫度下工(gong)作。
