Kev tawg hauv Lub Zog Cia: Tshiab Super Capacitor

Raws li kev tshawb fawb tshiab los ntawm Massachusetts lub koom haum thev naus laus zis (MIT), ob yam khoom siv feem ntau hauv tib neeg keeb kwm, cement thiab carbon dub (zoo ib yam li cov charcoal zoo heev), yuav dhau los ua cov khoom siv raw rau cov nqi qis dua tshiab. qhov system.

Cov kws tshawb fawb MIT tau pom tias ob cov ntaub ntawv no tuaj yeem ua ke nrog dej los ua supercapacitors (hloov cov roj teeb), uas tuaj yeem khaws cov hluav taws xob hluav taws xob. Nws tau hais tias cov thev naus laus zis no tuaj yeem tswj hwm kev ruaj ntseg hauv lub zog network txawm tias muaj kev hloov pauv hauv cov khoom siv hluav taws xob tauj dua tshiab, yog li txhawb kev siv lub zog tauj dua tshiab xws li hnub ci, cua, thiab lub zog tidal.
 

Piv txwv li, cov kws tshawb fawb hais tias lawv cov supercapacitors kawg tuaj yeem ua ke rau hauv lub hauv paus pob zeb ntawm lub tsev, qhov chaw uas lawv tuaj yeem khaws lub zog rau ib hnub ntawm tus nqi tsawg heev (lossis tsis muaj) thiab tseem muab lub zog tsim nyog rau lub tsev. Cov kws tshawb fawb tseem xav txog kev tsim txoj kev ua vaj tse uas tuaj yeem ua rau tsis muaj kev sib cuag rau cov tsheb hluav taws xob uas tsav tsheb ntawm txoj kev no.

Cov kev tshawb fawb tshiab tshaj plaws tau tshaj tawm tsis ntev los no hauv Kev Ua Haujlwm ntawm National Academy of Sciences (PNAS).

Lub capacitor yog ib qho cuab yeej yooj yim heev nyob rau hauv txoj cai, muaj ob daim hlau conductive rau hauv cov electrolyte thiab sib cais los ntawm ib daim nyias nyias. Thaum ib qho hluav taws xob raug siv rau lub capacitor, qhov zoo them ions los ntawm cov electrolyte sib sau ua ke ntawm cov phaj tsis zoo, thaum cov phaj zoo them cov nqi tsis zoo.

Vim tias daim nyias nyias ntawm daim hlau tiv thaiv kev tsiv teb tsaws ntawm cov ions raug them, qhov kev sib cais ntawm cov nqi no tsim ib qho hluav taws xob nruab nrab ntawm daim hlau, thiab lub capacitor yuav raug them. Ob lub rooj tsavxwm no tuaj yeem tuav cov nqi no rau lub sijhawm ntev thiab muab lawv sai sai thaum xav tau. Lub supercapacitor yog lub capacitor uas tuaj yeem khaws cov nqi ntau heev.
Tus nqi hluav taws xob ntawm lub capacitor tuaj yeem khaws cia nyob ntawm tag nrho thaj chaw ntawm nws cov phaj conductive. Tus yuam sij rau lub supercapacitor tshiab tsim los ntawm pab neeg yog nyob rau hauv ib txoj kev ntawm kev tsim cov cement-raws li cov ntaub ntawv, uas muaj tsis tshua muaj siab sab hauv cheeb tsam vim lawv ntom thiab interconnected conductive khoom network nyob rau hauv lawv ntim.

Tshwj xeeb, cov kws tshawb fawb tau ua tiav lub hom phiaj no los ntawm kev tso cov pa roj carbon dub, cement hmoov, thiab dej rau hauv cov pob zeb sib tov thiab tso cai rau nws kom khov. Thaum dej reacts nrog cement, nws ib txwm tsim ib tug branching network nyob rau hauv cov qauv, thiab carbon migrate mus rau hauv cov chaw no, tsim ib tug linear qauv nyob rau hauv lub hardened cement.

Cov qauv no muaj cov qauv forked, nrog cov ceg loj dua ua rau cov ceg me me, thiab lwm yam, thaum kawg ua rau thaj tsam loj heev hauv qhov ntim me me.
Tom qab ntawd muab cov khoom no tso rau hauv cov khoom siv electrolyte, xws li poov tshuaj chloride (ib ntsev), uas muab cov khoom siv uas ntim rau ntawm cov qauv carbon. Cov kws tshawb fawb tau pom tias ob lub tshuab hluav taws xob ua los ntawm cov khoom siv no tau sib cais los ntawm qhov chaw nyias nyias lossis txheej rwb thaiv tsev, tsim lub supercapacitor muaj zog heev.

Cov kws tshawb fawb taw qhia tias cov cement thiab carbon dub yog ob yam khoom uas muaj keeb kwm tsawg kawg yog ob txhiab xyoo. "Thaum koj muab lawv rau hauv ib txoj kev tshwj xeeb, koj tau txais cov khoom siv nanocomposite, uas yog thaum cov khoom ua tau zoo heev. Tsis tas li ntawd, cov ntsiab lus carbon yuav tsum tsawg heev, suav txog tsuas yog 3 feem pua ​​​​ntawm cov khoom sib xyaw, uas tuaj yeem tsim cov permeable. carbon network.
Cov kws tshawb fawb hais tias supercapacitors ua los ntawm cov khoom siv no muaj peev xwm pab tau lub ntiaj teb hloov mus rau lub zog tauj dua tshiab. Lub hauv paus tseem ceeb ntawm lub zog tsis muaj zog, xws li lub zog cua, hnub ci zog, thiab lub zog tidal, txhua tus tsim lawv cov khoom tsim tawm ntawm lub sijhawm sib txawv, uas feem ntau tsis sib haum nrog lub ncov ntawm kev siv hluav taws xob. Yog li ntawd, txoj kev khaws cia hluav taws xob yog qhov tseem ceeb.

Qhov kev thov rau cov tshuab hluav taws xob loj loj yog qhov siab heev, thiab cov roj teeb uas twb muaj lawm yog kim heev thiab feem ntau yog cia siab rau cov ntaub ntawv xws li lithium. Cov khoom siv ntawm lithium yog txwv, yog li muaj kev xav tau sai rau cov kev xaiv pheej yig dua. Qhov no yog qhov uas peb cov thev naus laus zis tau txais txiaj ntsig zoo vim tias cement yog nyob txhua qhov chaw, "lawv hais.
Pab neeg tshawb fawb tau suav tias 45 cubic meter-loj nano carbon dub doped pob zeb (sib npaug rau lub voos xwmfab nrog txoj kab uas hla ntawm kwv yees li 3.5 meters) yuav muaj peev xwm txaus khaws cia kwv yees li ntawm 10-kilowatt teev ntawm lub zog, uas suav tias yog nruab nrab siv hluav taws xob txhua hnub ntawm ib tsev neeg. Vim muaj peev xwm ntawm cov pob zeb ua kom nws lub zog, cov tsev tsim los ntawm cov khoom siv no tuaj yeem khaws lub zog tsim los ntawm cov hnub ci vaj huam sib luag los yog cua tshuab rau ib hnub thiab siv tau thaum xav tau. Tsis tas li ntawd, kev them nqi thiab kev tso tawm ceev ntawm supercapacitors yog nrawm dua li ntawm cov roj teeb.
Cov kws tshawb fawb kuj tau hais tias thawj zaug siv cov thev naus laus zis no tuaj yeem nyob hauv cov tsev sib cais, cov tsev, lossis cov chaw nyob deb ntawm daim phiaj hluav taws xob, uas tuaj yeem siv los ntawm cov hnub ci vaj huam sib luag txuas nrog cov cement supercapacitors.
Lawv hais tias lub kaw lus muaj peev xwm loj heev vim tias lub zog cia muaj peev xwm yog qhov ua haujlwm ncaj qha ntawm lub ntim electrode. Koj tuaj yeem tig 1 hli tuab electrode rau hauv 1m tuab electrode, thiab los ntawm kev ua li ntawd, koj tuaj yeem pib nthuav koj lub zog cia, los ntawm teeb pom kev LED rau ob peb feeb los muab lub zog rau tag nrho lub tsev.

Peb lub tuam txhab tau tsom mus rau qhov zoo tshaj plaws Copper End Cap, Fuse Terminal Contacts, (ELECTRICAL VEHICLE) EV Film Capacitor BusBar, (SOLAR POWER) PV Inverter BusBar, Laminated BusBar, Aluminium Cases rau lub zog tshiab, tooj liab / tooj dag / Aluminium / Stainless hlau Stamping Parts, thiab lwm yam khoom siv hluav taws xob Hlau Stamping thiab Vuam los ua ke rau ntau tshaj 18 xyoo hauv Suav teb. Peb pib ua haujlwm me me, tab sis tam sim no tau dhau los ua ib qho ntawm cov neeg muag khoom hauv EV thiab PV kev lag luam hauv Suav teb.
