陽極為鋁，陰極為電解液的電容，其正式名稱是鋁電解電容器，因?yàn)橛幸簯B(tài)存在，所以被稱為“液態(tài)”電容。

　　The anode is aluminum and the cathode is electrolyte. Its official name is aluminum electrolytic capacitor. Because there is liquid, it is called "liquid" capacitor.

　　理論上，或非商品的鋁電解電容并不需要額外的負(fù)極板，只要將負(fù)極引線插入電解液就行了。但作為實(shí)際產(chǎn)品，加一層鋁箔作為電解液的引導(dǎo)，方面鏈接，因?yàn)橐彩桥c正極板類似的鋁箔，所以常被誤解為負(fù)極板。

　　Theoretically, or non-commercial aluminum electrolytic capacitors do not need an additional negative plate, just insert the negative lead into the electrolyte. However, as an actual product, adding a layer of aluminum foil as the guide of electrolyte is often misunderstood as negative plate because it is similar to the positive plate.

　　而電解液是最傳統(tǒng)的電解質(zhì)，電解液是由GAMMAD丁內(nèi)酯有機(jī)溶劑加弱酸鹽電容質(zhì)經(jīng)過加熱得到的。普通意義上的鋁電解電容的陰極，都是這種電解液。

　　The electrolyte is the most traditional electrolyte, which is obtained by heating gamma butyrolactone organic solvent and weak acid salt capacitor. Generally speaking, the cathode of aluminum electrolytic capacitor is this kind of electrolyte.

　　當(dāng)貼片鋁電解電容使用電解液陰極有不少好處？

　　When chip aluminum electrolytic capacitor uses electrolyte cathode, there are many advantages?

　　首先，在于液體與介質(zhì)的接觸面積較大，這樣對(duì)提升電容量有幫助；

　　Firstly, the contact area between the liquid and the medium is large, which is helpful to improve the capacitance;

　　其次，使用電解液耐高溫能力不錯(cuò)，可使用SMT工藝，同時(shí)耐壓性也比較強(qiáng)；

　　Secondly, the high temperature resistance of electrolyte is good, SMT process can be used, and the pressure resistance is relatively strong;

　　此外，使用電解液做陰極的電解電容，當(dāng)介質(zhì)被擊穿之后，只要擊穿電流不持續(xù)，那么電容能夠自愈（金屬氧化物可以自動(dòng)生成）。

　　In addition, when the dielectric is broken down, as long as the breakdown current does not last, the capacitor can self-healing (metal oxide can be generated automatically).

　　電解液電容也有其不足處：

　　Electrolyte capacitance also has its disadvantages

　　首先是在高溫環(huán)境下容易揮發(fā)、滲漏、對(duì)壽命和穩(wěn)定性影響很大，在高溫高壓下的電解液還有可能瞬間汽化，體積增大引起爆炸；

　　First of all, it is easy to volatilize and leak in high temperature environment, which has great influence on life and stability;

　　其次是電解液所采用的離子導(dǎo)電法其導(dǎo)電率很低，只有0.01S/CM（電導(dǎo)率，歐姆的倒數(shù)），這造成電容的ESR值（等效串聯(lián)電阻、阻抗）特別高。

　　Secondly, the ionic conductivity method used in the electrolyte is very low, only 0.01s/cm (the reciprocal of conductivity and Ohm), which makes the ESR value of capacitance (equivalent series resistance and impedance) extremely high.

　　了解了貼片電解電容的優(yōu)缺點(diǎn)，我們才能選擇更加適合的電容元器件。

　　Understand the advantages and disadvantages of chip electrolytic capacitor, we can choose more suitable capacitor components.
