Chidhinha chakajairika se supercapacitor? Ndokumbirawo, heino polymer inoita kuti ive chitoro chemagetsi.
Masayendisiti kubva kuYunivhesiti yeWashington muSt. Louis akagadzira goko repolymer rinogona kushandura chidhinha kuita chidiki chekuchengetedza simba (supercapacitor). Zvese nekuda kwe iron oxide, dhayi inopa zvidhinha mavara ayo matsvuku.
Chidhinha chinodyisa diode? Is an. Mune ramangwana? Mwenje wemagetsi, imba yekuchengetedza simba, ...
Vatsvagiri kubva kuyunivhesiti yambotaurwa vakazvimisira ivo chinangwa chekushandisa zvinhu zviri pedyo nesu, zvakachipa uye zvakakurumbira. Pakati pezvimwe zvinhu, akawira pangura nezvidhinha. Zvakajairika zvidhinha zvevhu, izvo zvinoshanduka zvitsvuku nekuda kwekuvapo kwesimbi oxide. Ivo vakacherechedzwa kuti vane porous chimiro chinogona kushandiswa mukuchengetedza simba.
Porous zvivako zvinoshandiswawo, semuenzaniso, muma electrodes. Iine vhoriyamu isingaperi, iyo yakakura nzvimbo ye electrode, inokwidza iyo cell capacitance pakupedzisira. Asi kudzokera kune zvidhinha.

Masayendisiti akagadzira polymer (PEDOT) yakagadzirwa kubva kune nanofibers inokodzera kuvhara zvidhinha uye kuwedzera nzvimbo yavo. Polymer nanofibers inopindirana ne iron oxides iri muzvigadzirwa zvezvidhinha uye inokubvumira kuchengetedza imwe mutoro mairi. Kuchaja uku kuchave kwakaringana kwenguva yekugonesa diode:
Nekudzivirira mvura, zvidhinha zvinogona kuwedzerwa kuputirwa ne epoxy. Nekuda kwekushandiswa kwegel electrolyte inosunga matinji ese, chidhinha chakadaro chinogona kubata 90 muzana yekugona kwayo 10 zviuru (!) Kushanda kutenderera. Chishandiso - nekuti chatova mudziyo - chinogona kushanda mumhando ye -20 kusvika 60 madhigirii Celsius, inofananidzwa nemasero e-lithium-ion. voltage 3,6 volts inogona kuwanikwa ne serial kubatana kwezvidhinha zvitatu (zvidhinha).
Ehe, kunyangwe zvidhinha chinhu chakachipa, chinhu chepolymer chine nanofibers hachisi chokwadi chakazara. Zvisinei, tsvakurudzo inoratidza kukwanisa kukuru: fungidzira kuti imwe yemadziro eimba yedu inova nzvimbo yekuchengetedza simba. Izvi zvinogona kuva, semuenzaniso, kupatsanura, iyo inogona kugara ichiputswa uye inotsiviwa kana iyo link zvidhinha zvasakara.
Zvakaguma nei? Pachake simba rekuchengetedza yuniti yakabatana nedenga remba photovoltaic kuisirwa uye kusununguka kwakazara kubva kune anoshanda grid remagetsi.... Sarudzo iyi inonyanya kukosha kana iwe uchinzwa dzakawanda uye dzakawanda nhau dzekuti vanopa magetsi vari kuvhara masisitimu kure nekuti ivo havachakwanisa kubata nesimba rakawandisa rinogadzirwa.
Zvakakodzera kuverenga: Mabhuroko ekuchengetedza magetsi eakamira supercapacitors PEDOT
Izvi zvinogona kukufadza:
