Njerwa wamba ngati supercapacitor? Chonde, nayi polima yomwe imapanga malo ogulitsa magetsi.
Asayansi ochokera ku yunivesite ya Washington ku St. Louis adapanga chipolopolo cha polima chomwe chimatha kusintha njerwa kukhala kachipangizo kakang'ono kosungira mphamvu (supercapacitor). Zikomo chifukwa cha iron oxide, utoto womwe umapatsa njerwa mtundu wake wofiira.
Njerwa yodyetsa diode? Ndi a. M'tsogolomu? Magetsi a nyale, kusungirako magetsi kunyumba, ...
Ofufuza ochokera ku yunivesite yomwe tatchulayi adzipangira okha cholinga chogwiritsa ntchito zinthu zomwe zili pafupi ndi ife, zotsika mtengo komanso zotchuka. Mwa zina, anagwera pa dzimbiri ndi njerwa. Njerwa zadongo wamba, zomwe zimakhala zofiira chifukwa cha kukhalapo kwa iron oxide. Awona kuti ali ndi porous dongosolo lomwe lingagwiritsidwe ntchito posungira mphamvu.
Mapangidwe a porous amagwiritsidwanso ntchito, mwachitsanzo, mu ma electrode. Ndi voliyumu yokhazikika, malo okulirapo a electrode, amakweza mphamvu ya cell pamapeto pake. Koma kubwerera ku njerwa.
> Sabata yatsopano ndi batire yatsopano: LeydenJar ili ndi ma silicon anode ndi mabatire a 170%. nthawi ino
Asayansi apanga polima (PEDOT) yopangidwa kuchokera ku nanofibers yomwe ili yoyenera kupaka njerwa ndikuwonjezera malo awo. Ma nanofiber a polima amachita ndi ma oxides achitsulo zili mu zomangira njerwa ndi kukulolani kusunga katundu wina mmenemo. Mtengo uwu ukhala wokwanira kwakanthawi kuti uyambitse diode:
Kuti musatseke madzi, njerwa imatha kuphimbidwanso ndi epoxy. Chifukwa cha kugwiritsa ntchito gel electrolyte yomwe imamanga zigawo zonse, njerwa yotere imatha kusunga 90 peresenti ya mphamvu yake 10 zikwi (!) Ntchito zozungulira. chipangizo - chifukwa kale chipangizo - akhoza kugwira ntchito mu osiyanasiyana -20 mpaka 60 madigiri Celsius, amene ndi mmene maselo lithiamu-ion. voteji 3,6 volts angapezeke ndi siriyo kugwirizana kwa maulalo atatu (njerwa).
Zachidziwikire, ngakhale njerwa ndi zinthu zotsika mtengo, chinthu cha polima chokhala ndi nanofibers sizowona kwathunthu. Komabe, kafukufuku akuwonetsa kuthekera kwakukulu: taganizirani kuti limodzi la makoma a nyumba yathu limakhala malo osungiramo mphamvu. Izi zitha kukhala, mwachitsanzo, kugawa, komwe kumatha kugwetsedwa nthawi zonse ndikusinthidwa pomwe njerwa zolumikizira zatha.
Zotsatira zake? Chipinda chanu chosungira mphamvu cholumikizidwa ndi kuyika padenga la photovoltaic ndikudziyimira pawokha kuchokera pagulu lamagetsi lamagetsi... Lingaliro ili ndilofunika makamaka mukamva nkhani zowonjezereka kuti ogulitsa magetsi akutseka makonzedwe akutali chifukwa sangathenso kupirira mphamvu zowonjezera zomwe zimapangidwa.
Zoyenera kuwerenga: Ma block opulumutsa mphamvu a stationary supercapacitors PEDOT
Izi zingakusangalatseni:
