Ukuguga kwePhenomenon yeSupercapacitors

I-Supercapacitor: uhlobo olutsha lwe-electrochemical energy storage element, oluphuhliswe ukusuka kwi-1970 ukuya kwi-1980, eyenziwe ngama-electrode, i-electrolytes, i-diaphragms, abaqokeleli bangoku, njl., kunye nesantya sokugcina amandla okukhawuleza kunye nokugcinwa kwamandla amakhulu.I-capacitance ye-supercapacitor ixhomekeke kwisithuba se-electrode kunye nommandla we-electrode surface.Ukunciphisa i-electrode spacing ye-supercapacitor kunye nokwandisa indawo ye-electrode surface kuya kwandisa amandla e-supercapacitor.Ukugcinwa kwayo kwamandla kusekelwe kumgaqo wokugcinwa kwe-electrostatic.I-carbon electrode i-electrochemically kwaye izinzile, kwaye inokuhlawuliswa ngokuphindaphindiweyo ngamakhulu amawaka amaxesha, ngoko i-supercapacitors ingasetyenziselwa ixesha elide kuneebhetri.

Nangona kunjalo, ii-supercapacitors zinokuba neengxaki ngexesha lokusebenza, njengokuguga.Ukuguga kwee-supercapacitors kutshintsha i-electrodes, i-electrolytes kunye nezinye iinqununu ze-supercapacitor ezivela kwizinto eziphathekayo kunye neekhemikhali, ezibangela ukuguga kwee-supercapacitors, ezibangela ukuthotywa kokusebenza, kwaye oku kuthotywa akunakuguqulwa.

Ukuguga kwee-supercapacitors:

1. Iqokobhe elonakeleyo

Xa ii-supercapacitors zisebenza kwindawo efumileyo ixesha elide, ezinokukhokelela ngokulula ekuthotyweni kwentsebenzo kwaye zinciphise kakhulu ixesha lokusebenza.Umswakama emoyeni ungena kwi-capacitor kwaye uqokelele, kwaye uxinzelelo lwangaphakathi lwe-supercapacitor luyakha.Kwiimeko ezinzima, isakhiwo se-supercapacitor casing sichithwa.

2. Ukuwohloka kwe-Electrode

Esona sizathu siphambili sokuthotywa kokusebenza kwee-supercapacitors kukuwohloka kwe-porous activated carbon electrode.Kwelinye icala, ukuwohloka kwe-electrode ye-supercapacitor kubangele ulwakhiwo lwekhabhoni olusebenzayo lutshatyalaliswe ngokuyinxenye ngenxa ye-oxidation yomphezulu.Ngakolunye uhlangothi, inkqubo yokuguga nayo yabangela ukubekwa kokungcola kwi-electrode surface, okubangela ukuba ininzi ye-pores ivalwe.

3. Ukubola kwe-Electrolyte

Ukubola okungenakuguqulwa kwe-electrolyte, enciphisa kakhulu ixesha lokusebenza kwe-supercapacitors, enye imbangela yokuguga.Ukunciphisa i-oxidation ye-electrolyte ukuvelisa iigesi ezifana ne-CO2 okanye i-H2 kukhokelela ekwandeni koxinzelelo lwangaphakathi lwe-supercapacitor, kwaye ukungcola okuveliswa kukubola kwayo kunciphisa ukusebenza kwe-supercapacitor, ukwandisa i-impedance, kwaye kubangele ubuso bokukhanya. I-electrode ye-carbon esebenzayo ukuba ibe mbi.

4. Ukuzikhupha

Ukuvuza kwangoku okwenziwa ngokuzikhupha kwe-supercapacitor kwakhona kunciphisa kakhulu ixesha lokusebenza kunye nokusebenza kwe-supercapacitor.Ikhoyo ngoku iveliswa ngamaqela asebenzayo e-oxidized, kwaye amaqela asebenzayo ngokwawo aveliswa yi-electrochemical reactions kwi-electrode surface, eya kukhawulezisa ukuguga kwe-supercapacitor.

Oku ngasentla kukho izibonakaliso ezininzi zokuguga kwee-supercapacitors.Ukuba ukuguga kwe-capacitor kwenzeka ngexesha lokusetyenziswa, kuyimfuneko ukutshintsha i-capacitor ngexesha.
