Cov kws tshawb nrhiav ntawm Asmeskas Lub Tsev Haujlwm Saib Xyuas Lub Zog (DEE) Argonne Lub Tsev Haujlwm Arganne muaj kev tshawb pom ntev ntev hauv kev tshawb nrhiav cov roj teeb lithium-ion. Ntau ntawm cov txiaj ntsig no yog rau cov roj teeb cathrode, hu ua NMC, Nickel Manganese thiab cobalal Oxide. Lub roj teeb nrog cov Cathode no tam sim no powers chevrolet ntsia liaj qhov rooj.
Argonne cov kws tshawb nrhiav tau ua tiav lwm qhov sib tawg hauv NMC Cathodes. Pab pawg tshiab me me Cathle particle cov qauv yuav ua rau lub roj teeb ntau thiab muaj kev nyab xeeb ntawm voltages heev thiab muab sijhawm ntev dua.
"Tam sim no peb muaj kev taw qhia tias cov ntaub ntawv hluav taws xob tuaj yeem siv los ua cov ntaub ntawv siab," Khalil amin, cov khub sib cav, Argonne Emeritus.
"NMC Cov Catchodes tam sim no muaj kev ua haujlwm loj rau kev ua haujlwm siab," tus kws khomob uas hais tias, "tus kws khomob hais tias Guite Nrog them nqi-tawm cycling, kev ua tau zoo zuj zus vim kev tsim cov kab nrib pleb hauv cov Cathode hais. Rau xyoo lawm, cov kws tshawb nrhiav roj teeb tau nrhiav txoj hauv kev los kho cov kab nrib pleb no.
Ib txoj kev yav dhau los siv cov khoom me me me me ua tau ntau cov khoom me me. Cov kheej kheej loj yog polycrystalline, nrog crystalline nyob rau ntau yam kev paub. Raws li ib tug tshwm sim, lawv muaj dab tsi kws tshawb fawb hu cov noob ciaj ciam ntawm cov me me, uas tuaj yeem ua rau lub roj teeb tawg thaum lub voj voog. Txhawm rau tiv thaiv qhov no, Xu thiab Argonne cov npoj yaig tau dhau los ua ib qho kev tiv thaiv polymer ib puag ncig txhua qhov me me. Cov txheej no ib puag ncig loj kheej kheej kheej thiab me me nyob hauv lawv.
Lwm txoj hauv kev kom zam dhau qhov kev tawg no yog siv cov lus siv crystal. Electron cov ntawv me me ntawm cov lus qhia tau qhia tias lawv tsis muaj ciam teb.
Qhov teeb meem rau pab pawg tau hais tias Cathodes ua los ntawm coated polycrystals thiab ib lub muaju nkaus xwb tseem tawg thaum caij tsheb kauj vab. Yog li ntawd, lawv tau tshawb xyuas cov ntaub ntawv tshaj plaws ntawm cov ntaub ntawv cathode ntawm cov neeg tshaj lij (CHPS rau Nanomaterials (CNM) ntawm Asmeskas Lub Zog Kev Tshawb Fawb Lub Zog.
Ntau lub xoo hluav taws xob tshuaj xyuas tau ua rau tsib APS Caj npab (11-BM, 20-BM, ID-D, 11-ID-C thiab 34-ID-E). Nws hloov tawm tias dab tsi cov kws tshawb fawb xav yog ib qho siv lead ua ib qho, raws li pom los ntawm hluav taws xob thiab xoo hluav taws xob tawm tswv yim, ua tau ib tug ciam hauv sab hauv. Kev luam tawm thiab xa hluav taws xob electron metcopy ntawm CNMS paub tseeb tias qhov xaus no.
"Thaum peb saib saum npoo morphology ntawm cov lus no, lawv tau saib zoo li ib tus kws lij choj," synicist wenjun liu. Â� <但是, 当我们在 aps 使用一种称为同步加速器 使用一种称为同步加速器, 我们发现边界隐藏在内部. " Â� <但是, Koj puas yog 加速器 同步 同步 同步 射线 显微镜 显微镜 技术 和 时 时 时 时, 我们 发现 边界 在 在. ""Txawm li cas los xij, thaum peb siv tus txheej txheem hu ua Synchrotracton X-ray diffraction me me matchcopy thiab lwm yam kev qhia ntawm cov ciaj ciam tau muab zais rau sab hauv."
Qhov tseem ceeb, pab neeg tau tsim ib txoj hauv kev los tsim cov muaju sib luag tsis muaj ciam teb. Kuaj cov hlwb me nrog no ib-crystal catread ntawm ntau voltages pom ib lub zog ntim ib lub ntim ntim nrog tsis muaj kev poob hauv kev ua tau zoo tshaj 100 xeem mus. Hauv kev sib piv, NMC Cathodes tsim ntawm ntau cov muaju lossis coated polycrystals tsom lub peev xwm poob ntawm 60% txog 88% nyob rau tib lub neej.
Atomic nplai suav qhia cov tshuab ntawm cov cathode categility txo. Raws li Maria Changentist ntawm CNM, cov ciaj ciam yog ntau dua yuav plam oxygen atoms thaum lub roj teeb them dua li cov chaw deb ntawm lawv. Qhov kev poob no ntawm oxygen ua rau kev cuam tshuam ntawm lub voj voog ntawm tes.
"Peb cov kev suav sau tias yuav ua li cas tus ciam poom tuaj yeem ua rau oxygen raug tso tawm ntawm qhov kev kub siab," chan tau hais.
Tshem tawm cov ciam teb tiv thaiv cov pa tawm tswv yim, yog li kev txhim kho kev nyab xeeb thiab phais ntshauv ntawm cov Cathoo. Oxygen Kev Ntsuas Hluav Taws Xob nrog APS thiab cov teeb meem loj heev ntawm Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Hauv Tebchaws
"Tam sim no peb muaj cov lus qhia uas roj teeb hluav taws xob tuaj yeem siv los ua cov ntaub ntawv cathhoe thiab ua haujlwm ntawm Khalility Amin, Cov Neeg Sib Txawv, Argonne Neeg tsav tsheb Argitus. Â� <该指南应适用于 nmc 以外的其他正极材料. " Â� <该指南应适用于 nmc 以外的其他正极材料. ""Cov lus qhia yuav tsum tau siv rau cov ntaub ntawv cathohod lwm dua NMC."
Ib tsab xov xwm hais txog txoj kev kawm no tshwm sim hauv phau ntawv ceev xwm xwm lub zog. Ntxiv rau Xu, amin, Liu thiab Changu tus sau yog Xiang, YAUT ZHUA CHAILYA WUENG, INUMJUNU, TUENGJUN SOUR, TUA ZHUE, ming DU, thiab Zonhaai Chen.
