Nyob rau hauv cov kev coj ua lag luam lithium-ion hluav taws xob, qhov kev txwv tsis pub muaj hluav taws xob. Tshwj xeeb, cov khoom tsis muaj txiaj ntsig ntawm cov khoom siv hluav taws xob zoo ncaj qha rau kev ua haujlwm ntawm cov kev ua haujlwm ntawm cov khoom siv hluav taws xob. Nws yog ib qho tsim nyog los ntxiv tus neeg sawv cev tsim nyog los txhim kho cov khoom siv hluav taws xob kom muab cov channel txuas ntxiv rau cov khoom siv hluav taws xob thiab ua kom cov khoom siv hluav taws xob tau siv. Yog li ntawd, tus neeg sawv cev ntawm cov neeg coj ua tseem yog cov khoom siv tsis tau hauv cov khoom siv roj teeb lithium ion ntawm cov khoom siv nquag.

Cov kev ua tau zoo ntawm tus neeg saib xyuas cov neeg ua haujlwm nyob ntawm seb cov qauv ntawm cov qauv ntawm cov ntaub ntawv thiab cov cwj pwm uas nws tau sib cuag nrog cov khoom siv nquag. Feem ntau siv lithium ion roj teeb cov neeg sawv cev muaj cov yam ntxwv hauv qab no:

(1) Carbon Dub: Tus qauv ntawm Carbon Dub yog qhia los ntawm cov qib kev sib sau ua ke cov pa roj carbon dub rau hauv cov saw hlau lossis cov duab txiv hmap. Cov khoom zoo, cov saw hluav taws xob nrawm, thaj chaw loj tshwj xeeb, thiab cov khoom muaj txiaj ntsig, uas muaj txiaj ntsig los ua cov saw khi ntawm electrode. Ua tus sawv cev ntawm cov neeg sawv cev sib koom ua ke, carbon dub yog tam sim no feem ntau dav siv cov neeg ua haujlwm. Qhov tsis zoo yog tias tus nqi siab yog siab thiab nws yog qhov nyuaj rau kev tawg.

(2)Npaim: Caws duab graphite yog tus cwj pwm los ntawm cov particle loj nyob ze rau ntawm qhov zoo thiab tsis zoo cov khoom siv, thiab hluav taws xob tshwj xeeb. Nws ua raws li cov ntawm lub network hauv lub roj teeb, thiab hauv cov tsis zoo electrode, nws tsis tuaj yeem txhim kho kev coj ua, tab sis kuj muaj peev xwm.

(3) P-li: Super P-li yog tus yam ntxwv me me, zoo ib yam li cov kab ke ntawm cov kab ntxwv hauv lub roj teeb, uas yog qhov ua tau zoo heev rau kev tsim lub network. Qhov tsis zoo yog tias nws yog qhov nyuaj rau kev tawg.

(4)Cov Nanotubes (CNTs): CNTs yog cov neeg sawv cev cov neeg sawv cev uas tau tshwm sim nyob rau xyoo tas los no. Lawv feem ntau muaj ib lub cheeb ntawm txog 5nm thiab ntev ntawm 10-20um. Lawv tsis tuaj yeem ua raws li "xaim hluav taws xob" hauv kev tshaj tawm tes hauj lwm, tab sis kuj tseem muaj ob chav hluav taws xob nyhuv los muab kev ua si rau cov neeg muaj txiaj ntsig zoo ntawm cov supercapacitors. Nws zoo thermal conductivity tseem muaj kev pab rau cua sov thaum lub roj teeb thiab tawm, txo cov roj teeb kev ua tau zoo thiab ua kom muaj roj teeb lub neej kub.

Raws li tus neeg sawv cev, CNTs tuaj yeem siv ua ke nrog ntau cov ntaub ntawv electrode zoo los txhim kho lub peev xwm, feem pua ​​ntawm cov khoom siv / roj teeb. Cov ntaub ntawv hauv electrode zoo uas tuaj yeem siv suav nrog: LICADOOT2, LINOO2, LITEPO4, polymer zoo electrode, LI3v2 (po4) 3, manganese oxide, thiab zoo li.

Piv nrog rau lwm cov neeg sawv cev uas muaj cov pa roj carbon monoxide muaj ntau yam zoo ua cov roj ntsha zoo thiab tsis zoo rau cov roj teeb lithium. Cov Nanotubes muaj hluav taws xob siab. Tsis tas li ntawd, CNTs muaj cov nam loj piv, thiab tus nqi ntxiv tuaj yeem ua tiav qhov kev sib ntxiv ntawm cov hluav taws xob hauv lub chaw nyob hauv lub nroog lossis hauv zos). Txij li thaum cov pa roj carbon nanotubes tuaj yeem tsim cov khoom lag luam hluav taws xob zoo ib yam li cov khoom siv hluav taws xob zoo sib xws tuaj yeem ua tiav nrog tsuas yog 0.2 wt% ntawm swcnts.

(5)Hoobyog hom tshiab ntawm ob-seem hloov kho cov khoom siv roj carbon roj carbon thiab thermal ua haujlwm. Cov qauv tso cai tso cai rau daim ntawv graphene kom ua raws li cov khoom sib cuag, yog li ntawd cov tshuab hluav taws xob tuaj yeem ua rau thaj chaw ob-seem los ua ib qho chaw loj uas ua rau thaj chaw loj. Yog li nws tau txiav txim siab raws li tus neeg sawv cev uas zoo tshaj plaws tam sim no.

Cov pa roj carbon dub thiab cov khoom siv nquag muaj nyob rau hauv kev sib tiv tauj, thiab tuaj yeem nkag mus rau hauv cov khoom ntawm cov khoom siv nquag ntawm cov ntaub ntawv nquag. Cov pa roj carbon nanotubes yog nyob rau hauv kab kev tiv toj, thiab tuaj yeem txuas cov qauv sib tham, thiab nws tsis yooj yim rau lub cev ua kom tiav. Txawm hais tias tus nqi ntawm graphene ntxiv yog tsis tu ncua, nws yog qhov nyuaj kom tau siv cov khoom siv nquag, thiab diffuse li ions thiab tsis zoo rau hluav taws xob. Yog li no, cov khoom no muaj qhov ua tau zoo ntxiv. Sib tov cov pa roj av dub lossis carbon nanotubes nrog graphene los tsim qhov kev ua tiav ntau dua tuaj yeem txhim kho cov kev ua tau zoo ntxiv ntawm electrode.

Ib qho ntxiv, los ntawm qhov kev pom ntawm graphene, kev ua yeeb yam ntawm daim duab dub los ntawm kev npaj sib txawv, thiab qhov tuab ntawm cov khoom siv hluav taws xob cuam tshuam rau cov neeg sawv cev ntawm cov neeg sawv cev. Ntawm lawv, txij li kev ua haujlwm ntawm tus neeg saib xyuas kev coj ua yog tsim lub tshuab hluav taws xob, yog tias cov neeg saib xyuas hluav taws xob, yog tias tsim kev tsim kho hluav taws xob zoo. Piv nrog cov tsoos carbon dog dig tus neeg sawv cev, Graphene muaj cov khoom lag luam saum npoo av, thiab cov nyhuv π conjugate ua rau nws yooj yim rau agglomerate hauv cov ntawv thov kev siv. Yog li ntawd, yuav ua li cas graphene tsim ib qho kev hloov kho zoo thiab siv tag nrho cov teeb meem tseem ceeb uas yuav tsum tau daws ntawm cov duab graphene.
