Supercapacitors yog hu ua hluav taws xob ob txheej capacitors thiab farad capacitors, uas tau tsim txij li xyoo 1980s.Tsis zoo li cov capacitors ib txwm muaj, supercapacitors yog ib hom tshiab ntawm electrochemical capacitors, uas nyob nruab nrab ntawm cov capacitors thiab roj teeb, thiab tsis muaj tshuaj lom neeg thaum lub sij hawm khaws cia.
Supercapacitors muaj cov yam ntxwv ntawm kev them nyiaj ceev ceev, ntau pua txhiab zaus ntawm kev them nqi thiab tawm, lub zog cia, kev tiv thaiv ib puag ncig thiab tsis muaj kuab paug, thiab lwm yam, thiab maj mam hloov cov roj teeb, thiab muaj peev xwm ua lag luam zoo.
Supercapacitors feem ntau yog tsim los ntawm electrodes, tam sim no collectors, separators ntawm electrodes thiab electrolyte.Ntawm lawv, cov khoom siv electrode yog ib qho tseem ceeb cuam tshuam thiab txiav txim siab qhov kev ua tau zoo ntawm supercapacitors.Cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob muaj xws li cov ntaub ntawv carbon-based electrode, hlau oxide electrode cov ntaub ntawv, thiab cov khoom siv polymer electrode.Muaj ntau yam kev faib tawm ntawm cov ntaub ntawv carbon-based electrode, hlau oxide electrode cov ntaub ntawv, thiab cov khoom siv polymer electrode.
Ntawm cov khoom siv hluav taws xob supercapacitor, cov ntaub ntawv carbon-based yog cov kev tshawb fawb ntxov tshaj plaws thiab paub tab technology.Cov ntaub ntawv carbon-based electrode feem ntau tau kawm yog: activated carbon, activated carbon fiber, thiab carbon aerogel.
1. Cov pa roj carbon activated yog cov khoom siv carbon electrode siv hauv supercapacitors thaum pib.Nws qhov kev ua tau zoo yog: thaj chaw loj tshwj xeeb;tsim pore qauv;siab tshuaj stability;txheej txheem yooj yim;tus nqi qis, tsim nyog rau kev tsim khoom loj.
2. Cov pa roj carbon activated: Nws yog cov khoom siv hauv ib puag ncig nrog rau kev ua kom muaj zog dua li cov pa roj carbon activated.Qhov chaw siab saum npoo tau qhib cov ntaub ntawv carbon fiber tau los ntawm nws tau ua tiav siv los ua cov khoom lag luam electrode.
3.Carbon aerogel: Nws yog cov khoom siv sib txuas nrog cov khoom sib txuas nrog cov qauv sib txuas.Nws muaj porosity, zoo conductivity, loj deg cheeb tsam, siab porosity, dav pore loj faib, thiab muaj peev xwm ua hluav taws xob.Nws yog cov khoom siv hluav taws xob zoo tagnrho rau kev npaj hluav taws xob ob txheej capacitors.
JYH HSU (JEC) Electronics Ltd (los yog Dongguan Zhixu Electronic Co., Ltd.) tau koom nrog hauv kev lag luam hluav taws xob ntau xyoo, thiab peb cov kws tshaj lij kev lag luam tuaj yeem pab koj daws cov teeb meem ntsig txog.Thaum muas varistors, koj yuav tsum paub seb cov khoom puas los ntawm cov tuam txhab tsis tu ncua.Lub chaw tsim khoom varistor zoo tuaj yeem txo ntau yam teeb meem tsis tsim nyog.
