Aluminium Electrolytic Capacitor Khoom

Cov khoom siv anode
High-purity aluminium foil (tshaj 99.9%): Siv los ua qhov zoo electrode, qhov saum npoo yog electrochemically etched los ua cov qauv ntxeem tau thiab ntxiv oxidized los ua ib qho txhuas oxide (Al₂O₃) dielectric zaj duab xis. Cov yeeb yaj kiab no yog nyias nyias (li 1.3 nm / V), muaj cov yam ntxwv kho kom zoo, thiab ua haujlwm raws li cov txheej txheem tseem ceeb ntawm lub capacitor.

Cov khoom siv Cathode
Cathode aluminium foil: Feem ntau cov hlau txhuas ntawv ci uas muaj cov impurities (xws li tooj liab, magnesium, thiab lwm yam), etched kom nce qhov chaw saum npoo tab sis tsis tsim cov oxide zaj duab xis, ua haujlwm tsuas yog cov txheej txheem txhuas nrog qhov siab tsis tshua muaj hluav taws xob (txog 0.5 V).

Electrolyte: Ua haujlwm raws li qhov tseeb cathode, muab faib ua
Cov kua dej electrolyte: Organic tov xws li ethylene glycol + borate + additives;
Khoom electrolyte: Cov khoom siv hluav taws xob (xws li PEDOT) lossis manganese dioxide (MnO₂).

Cov khoom sib cais thiab kev txhawb nqa
Electrolytic ntawv: Ultrapure cellulose microporous daim ntawv, impregnated nrog electrolyte, cais anode thiab cathode foils thaum ua ions.

Cov ntaub ntawv txhuas, roj hmab ntsaws, tawg- pov thawj valve: Tsim cov qauv kev sib khi, feem ntau siv cov roj hmab butyl, txhuas, thiab lwm yam, kom ntseeg tau tias muaj kev tiv thaiv siab thiab kev nyab xeeb.

Tshiab Anode Structures
Qhov tseeb patents siv porous aluminium spheres + ib txwm txhuas hmoov sintered txheej los ua cov ntawv ci anode, tsim kom muaj qhov tsawg -impedance, siab tshwj xeeb capacitance conductive network los txhim kho kev ua haujlwm ntawm lub capacitor.
