Nava: Peb cov nanotube electrodes muaj 3 npaug ntawm lub peev xwm thiab muab 10 npaug ntawm lub zog hauv lithium-ion hlwb.
Lub lim tiam tshiab thiab lub roj teeb tshiab. Fabkis supercapacitor chaw tsim tshuaj paus Nawa hais tias nws tau pib tsim tshiab nanotube electrodes rau lithium-ion roj teeb. Nws yog assumed tias vim hais tias nyob rau hauv parallel kev npaj ntawm nanotubes, lawv muaj peev xwm khaws peb zaug ntau tshaj li carbon anodes.
Nawa's New 3D Anodes: Muaj zog, zoo dua, nrawm dua, muaj zog dua
Niaj hnub nimno lithium-ion anodes feem ntau yog tsim los ntawm graphite los yog activated carbon (los yog txawm tias cov pa roj carbon activated los ntawm graphite), vim lawv cov qauv ntxeem tau tso cai rau ntau cov ions khaws cia. Qee lub sij hawm cov pa roj carbon sib xyaw nrog silicon thiab ib puag ncig los ntawm nano-txheej txheej kom tsis txhob o ntawm cov khoom.
Koj tuaj yeem hnov txog cov khoom siv rau kev siv cov silicon ntshiab, hais tias Tesla lossis Samsung SDI.
> Ua tiav cov khoom tshiab Tesla: hom 4680, silicon anode, "qhov zoo tshaj plaws txoj kab uas hla", series ntau lawm hauv 2022.
Nava hais tias cov qauv ntawm cov pa roj carbon yog qhov nyuaj heev rau kev txav ions. Hloov cov pa roj carbon, lub tuam txhab xav siv cov pa roj carbon nanotubes, uas tau tshaj tawm tias twb tau siv nyob rau hauv cov chaw tsim khoom supercapacitors. Parallel nanotubes tsim ntsug "notches" uas ions tuaj yeem kho tau yooj yim. Hais lus:
Nws tuaj yeem xav tias txhua tus nanotubes nyob rau hauv lub anode nyob rau hauv xws li ib txoj kev uas ions txav mus los ntawm lawv mus txog rau thaum xaiv qhov chaw yooj yim. Nava hais tias "Yog tsis taug kev nyob ib ncig ntawm cov qauv ntxeem tau ntawm classical anode, cov ions tsuas yog taug kev ob peb nanometers es tsis txhob micrometers, ib yam li cov electrodes classical," Nava hais.
Cov lus kawg qhia tau hais tias nanotubes tuaj yeem ua raws li cathodes - lawv txoj haujlwm yuav nyob ntawm cov khoom uas yuav nyob ntawm lawv qhov chaw. Nef tsis txiav txim siab siv silicon vim tias cov pa roj carbon nanotubes yuav npog nws zoo li lub tawb, yog li cov qauv yuav tsis muaj lub sijhawm los o. Crush teeb meem daws!
> Siv cov roj ntsha lithium-ion tawm ntawm lub txee nrog silicon anode. Them sai dua refueling nrog hydrogen
Nws yuav zoo li cas nrog cov tsis muaj hlwb uas siv nanotubes? Zoo, lawv yuav tso cai:
- kev siv cov 10 npaug ntau dua them thiab tawm lub zogdab tsi tam sim no
- tsim muaj tswv yim roj teeb nrog lub zog ceev 2-3 zaug siab dua los ntawm contemporaries,
- txuas roj teeb lub neej los ntawm tsib los yog kaum zaugvim nanotubes yuav tsis pub cov txheej txheem uas rhuav tshem lithium-ion hlwb (qhov chaw).
Cov txheej txheem ntawm aligning nanotubes nyob rau hauv ib tug kab yuav tsum yog trivial yooj yim, liam tias tib lub mechanism uas yog siv los looj tsom iav thiab photovoltaic hlwb nrog ib tug anti-reflective txheej. Nawa khav theeb tias nws tuaj yeem loj hlob mus txog qhov sib npaug ntawm nanotubes ntawm qhov nrawm mus txog 100 micrometers (0,1 mm) ib feeb - thiab siv cov thev naus laus zis no hauv nws cov supercapacitors.
Yog tias Nava cov lus thov muaj tseeb thiab cov electrodes tshiab tau muag, qhov no yuav txhais tau rau peb:
- hluav taws xob tsheb yog sib dua li combustion tsheb, tab sis nrog ib tug ntev ntau yam,
- muaj peev xwm them hluav taws xob nrog lub peev xwm ntawm 500 ... 1 ... 000 kW, uas yog luv dua li refueling,
- nce nyob rau hauv mileage ntawm electricians tsis tas yuav hloov lub roj teeb los ntawm tam sim no 300-600 txhiab mus rau 1,5-3-6 lab kilometers,
- thaum tuav lub roj teeb loj tam sim no: rechargeable, hais txhua ob lub lis piam.
Navah thawj tus khub yog Fabkis roj teeb chaw tsim khoom Saft, uas koom tes nrog PSA Group thiab Renault hauv European Battery Alliance.
