M'zaka zaposachedwa, ndi kutchuka kwa magalimoto, mitundu ndi kuchuluka kwa zinthu zamagetsi zamagalimoto zikuwonjezeka.Zambiri mwazinthuzi zili ndi njira ziwiri zoperekera magetsi, imodzi yochokera mgalimoto yokha, mphamvu yoperekedwa kudzera munjira yoyatsira ndudu yagalimoto.Zina zimachokera ku mphamvu zosunga zobwezeretsera, zomwe zimagwiritsidwa ntchito kuti chipangizocho chizigwira ntchito mphamvu ya choyatsira ndudu ikazimitsidwa.Pakadali pano, zinthu zambiri zamagalimoto zamagetsi zimagwiritsa ntchito mabatire a lithiamu-ion amadzimadzi ngati magwero amagetsi osungira.Koma ma supercapacitor akusintha pang'onopang'ono mabatire a lithiamu-ion.Chifukwa chiyani?Tiyeni choyamba timvetsetse momwe zida ziwiri zosungira mphamvu zimagwirira ntchito.
Momwe ma supercapacitors amagwirira ntchito:
Ma supercapacitor amagwiritsa ntchito carbon-based actives, conductive carbon black and binder osakanizidwa ngati pulasitiki, ndipo amagwiritsa ntchito polarized electrolyte kuti atenge ma ion abwino ndi oyipa mu electrolyte kuti apange mawonekedwe osanjikiza awiri amagetsi osungira mphamvu.Palibe mankhwala zimachitika panthawi yosungirako mphamvu.
Mfundo ntchito lithiamu batire:
Mabatire a lithiamu makamaka amadalira kayendedwe ka lithiamu ion pakati pa ma elekitirodi abwino ndi oipa kuti agwire ntchito.Panthawi yolipiritsa ndi kutulutsa, ma ion a lithiamu amalumikizidwa ndikulumikizana m'mbuyo ndi mtsogolo pakati pa maelekitirodi awiriwa.Pa kulipiritsa, ma ion a lithiamu amachotsedwa ku electrode yabwino ndikulumikizana ndi electrode yoyipa kudzera mu electrolyte, ndipo ma elekitirodi olakwika amakhala m'malo olemera a lithiamu.Kulipiritsa ndi kutulutsa ndikusintha kwamankhwala.
Kuchokera ku mfundo zogwirira ntchito za zinthu ziwiri zomwe zili pamwambazi zosungiramo mphamvu, zimatheka chifukwa chake kugwiritsa ntchito ma supercapacitor mu zojambulira zoyendetsa kungalowe m'malo mwa mabatire a lithiamu-ion.Zotsatirazi ndi zabwino za ma supercapacitor omwe amagwiritsidwa ntchito pojambulira zoyendetsa:
1) Mfundo yogwira ntchito ya mabatire a lithiamu-ion ndikusungira mphamvu zamagetsi, ndipo pali zoopsa zobisika.Ubwino wake ndikuti mukasiya magetsi agalimoto, mutha kukhalabe ndi nthawi ya batri, koma ma lithiamu ion ndi ma electrolyte amatha kuyaka komanso kuphulika.Mabatire a lithiamu-ion, akangokhala ochepa, amatha kuyaka kapena kuphulika.Supercapacitor ndi gawo la electrochemical, koma palibe mankhwala omwe amapezeka panthawi yake yosungira mphamvu.Njira yosungira mphamvuyi ndi yosinthika, ndipo ndichifukwa chake supercapacitor imatha kulipiritsidwa mobwerezabwereza ndikutulutsidwa kangapo.
2) Kuchulukana kwamphamvu kwa ma supercapacitor ndikokwera kwambiri.Izi ndichifukwa choti kukana kwamkati kwa ma supercapacitors ndikocheperako, ndipo ma ion amatha kusonkhanitsidwa mwachangu ndikumasulidwa, omwe ndi apamwamba kwambiri kuposa mphamvu ya mabatire a lithiamu-ion, zomwe zimapangitsa kuthamanga ndi kutulutsa kwa ma supercapacitor kukhala okwera kwambiri.
3) Kutentha kwakukulu kwa mabatire a lithiamu-ion sikwabwino.Nthawi zambiri, mulingo wachitetezo umakhala wapamwamba kuposa madigiri 60 Celsius.Pankhani ya kutentha kwambiri kudzuwa kapena kufupika kwafupipafupi, ndizosavuta kuyambitsa kuyaka modzidzimutsa ndi zinthu zina.The supercapacitor ali lonse kutentha ntchito osiyanasiyana mpaka -40 ℃ ~ 85 ℃.
4) Ntchitoyi imakhala yokhazikika ndipo nthawi yozungulira ndi yayitali.Popeza kulipiritsa ndi kutulutsa kwa supercapacitor ndizochitika zakuthupi ndipo sizimaphatikizapo ndondomeko ya mankhwala, kutayika kumakhala kochepa kwambiri.
5) Super capacitors ndi obiriwira komanso okonda zachilengedwe.Mosiyana ndi mabatire a lithiamu-ion, ma supercapacitor sagwiritsa ntchito zitsulo zolemera ndi zinthu zina zovulaza.Malingana ngati kusankha ndi kupanga ndizomveka, palibe chiwopsezo cha kuphulika kwamphamvu pansi pa kutentha kwakukulu ndi malo othamanga kwambiri panthawi yogwiritsira ntchito, yomwe ili yoyenera pazochitika zogwiritsira ntchito magalimoto.
6) The supercapacitor akhoza welded, kotero palibe vuto monga ofooka batire kukhudzana.
7) Palibe dera lapadera lolipiritsa ndi kuwongolera kutulutsa kofunikira.
8) Poyerekeza ndi mabatire a lithiamu-ion, ma supercapacitors alibe vuto lililonse pakugwiritsa ntchito nthawi yawo chifukwa cha kuchulukirachulukira komanso kutulutsa.Zachidziwikire, ma supercapacitor amakhalanso ndi zovuta zanthawi yochepa yotulutsa komanso kusintha kwakukulu kwamagetsi panthawi yotulutsa, chifukwa chake nthawi zina zapadera ziyenera kugwiritsidwa ntchito ndi mabatire.Mwachidule, ubwino wa ma supercapacitor ndi oyenera kugwiritsa ntchito zinthu zomwe zili m'galimoto, ndipo chojambulira choyendetsa galimoto ndi chitsanzo chimodzi.
Zomwe zili pamwambapa ndizabwino za super capacitor pamagalimoto amagalimoto.Tikukhulupirira kuti ndizothandiza kwa anthu omwe akufuna kuphunzira za ma super capacitor.JYH HSU(JEC) Electronics Ltd (kapena Dongguan Zhixu Electronic Co., Ltd.) yakhala ikudzipereka ku kafukufuku ndi chitukuko, kupanga ndi malonda a capacitors otetezeka kwa zaka zoposa 30.
Takulandilani kudzacheza nafe patsamba lathu lovomerezeka ndikulumikizana nafe pamafunso aliwonse.
