Ib qho cib zoo li lub supercapacitor? Thov, ntawm no yog cov polymer uas ua rau nws lub khw muag khoom hluav taws xob.
Cov kws tshawb fawb los ntawm University of Washington hauv St. Louis tsim lub plhaub polymer uas tuaj yeem tig lub cib rau hauv lub zog me me cia khoom (supercapacitor). Txhua yam ua tsaug rau hlau oxide, xim xim uas muab cib nws cov xim liab.
Lub cib pub ib lub diode? Yog ib. Yav tom ntej? Lub teeb hluav taws xob, khoom siv hluav taws xob hauv tsev, ...
Cov kws tshawb fawb los ntawm cov tsev kawm ntawv uas tau hais los saum no tau teeb tsa lawv tus kheej lub hom phiaj ntawm kev siv cov khoom uas nyob hauv peb cheeb tsam, pheej yig thiab nrov. Ntawm lwm yam, nws poob rau xeb thiab cib. Zoo tib yam av nplaum cib, uas tig liab vim muaj hlau oxide. Lawv tau raug pom tias muaj cov qauv ntxeem tau uas tuaj yeem siv rau hauv lub zog cia.
Porous lug kuj siv, piv txwv li, hauv electrodes. Nrog rau qhov ntim tas li, qhov loj ntawm thaj tsam electrode, qhov siab dua ntawm cov cell capacitance kawg. Tab sis rov qab mus rau lub cib.

Cov kws tshawb fawb tau tsim cov khoom siv polymer (PEDOT) ua los ntawm nanofibers uas tsim nyog rau txheej cib thiab ua kom lawv thaj chaw ntau ntxiv. Polymer nanofibers teb nrog hlau oxides muaj nyob rau hauv cov khoom siv cib thiab tso cai rau koj khaws ib qho kev thauj khoom hauv nws. Qhov kev them nqi no yuav txaus rau qee lub sijhawm los siv lub zog diode:
Rau waterproofing, lub cib yuav ntxiv coated nrog epoxy. Ua tsaug rau kev siv cov gel electrolyte uas khi txhua txheej, xws li cib tuaj yeem tuav 90 feem pua ntawm nws lub peev xwm ntawm 10 txhiab (!) Ua haujlwm voj voog. Cov cuab yeej - vim tias nws yog ib qho khoom siv - tuaj yeem ua haujlwm nyob rau hauv thaj tsam ntawm -20 txog 60 degrees Celsius, uas yog qhov zoo rau lithium-ion hlwb. zog 3,6v tuaj yeem tau txais los ntawm serial kev sib txuas ntawm peb qhov txuas (cib).
Tau kawg, txawm tias cib yog cov khoom pheej yig, cov khoom siv polymer nrog nanofibers tsis muaj tseeb. Txawm li cas los xij, kev tshawb fawb qhia tau tias muaj peev xwm zoo: xav txog tias ib qho ntawm cov phab ntsa ntawm peb lub tsev dhau los ua lub zog cia hauv zos. Qhov no tuaj yeem ua tau, piv txwv li, ib qho kev faib tawm, uas tuaj yeem raug rhuav tshem thiab hloov pauv thaum qhov txuas bricks raug hnav.
Cov nyhuv? Tus kheej lub zog cia chav txuas nrog lub ru tsev photovoltaic installation thiab ua tiav kev ywj pheej los ntawm tus neeg teb xov tooj daim phiaj hluav taws xob... Qhov kev txiav txim siab no tseem ceeb tshwj xeeb tshaj yog thaum koj hnov ntau thiab ntau cov xov xwm hais tias cov khoom siv hluav taws xob tau kaw cov kev teeb tsa nyob deb vim lawv tsis tuaj yeem tiv nrog lub zog ntau dhau lawm.

Qhov no yuav txaus siab rau koj:
