Durability: Cov cuab yeej twb siv lithium-ion hlwb nrog silicon anodes. Kev xaiv? Wb tsis txhob tham
Sila Nano tus thawj tswj hwm tweeted tias lithium-ion hlwb nrog silicon anodes nyuam qhuav ua lawv txoj kev mus rau thawj ntaus ntawv. Qhov no yog Whoop 4.0 Fitness Tracker, uas cov chaw tsim khoom thov muaj roj teeb nrog 17 feem pua siab zog dua li cov cuab yeej dhau los.
Silicon anodes yog thawj zaug hauv cov khoom siv hauv tsev me me thiab yav tom ntej, piv txwv li, hauv Mercedes
Sila Nano tsis xav kom nthuav tawm cov kev txwv ntawm cov hlwb tshiab (voltage hla cov electrodes, tag nrho lub zog ceev, thiab lwm yam). Nws kuj tseem tsis tau qhia tias leej twg ua cov roj teeb tiag tiag vim Sila Nano tsuas yog cov chaw tsim khoom ntawm silicon hmoov anode thiab cov hlwb tau tsim los ntawm lwm tus. Yog li peb tsuas muaj 17 feem pua hais thiab cov lus thov tias cov roj teeb tshiab txhais tau tias cov sensors tshiab tuaj yeem siv tau thiab tib lub roj teeb lub neej thaum txo cov khoom ntim los ntawm 1/3 (qhov chaw, them nyiaj; qhov chaw).
Niaj hnub nimno lithium-ion cell anodes siv ntau hom carbon, qee zaum nrog ntxiv ntawm silicon. Lub silicon anode muaj qhov zoo uas nws tuaj yeem tuav thiab khaws cia txog li 10 npaug ntau dua lithium ions dua li graphite anode. Theoretically ces lub roj teeb uas siv silicon tuaj yeem muaj 10 npaug ntawm lub peev xwm.
Txawm li cas los xij, qhov tseeb tsis zoo rau peb. Lub peev xwm siab dua ntawm cov qauv silicon txhais tau hais tias 1) nyob rau hauv thawj theem ntawm lub cell ua haujlwm, thaum ib txheej passivation yog tsim, ntau lithium ions yog immobilized mus ib txhis. Thiab qhov no yog 2) lithium ions thawb sib nrug ntawm cov qauv silicon ntau dua (lawv yuav tsum nyob rau qhov chaw), uas ua rau kev puas tsuaj ntawm cov anode. Raws li qhov tshwm sim ntau lithium yuav tsum tau ua silicon anode cell (= tus nqi siab dua) Oraz ntxiv stabilization mechanisms thaiv qhov o ntawm cov qauv.
Nws zoo nkaus li tias Sila Nano tau tswj kom daws tau yam tsawg kawg ntawm qee qhov teeb meem thiab tib lub sijhawm tsim cov txheej txheem rau kev tsim khoom ntawm silicon anodes. Tshaj li 10 xyoo dhau los, cov txheej txheem tsim khoom tau nrawm dua ib txhiab zaug (1 zaug). Rau lithium-ion hlwb nrog silicon anodes mus rau hauv lub tsheb, cov txheej txheem tam sim no yuav tsum tau nrawm dua los ntawm qhov tseem ceeb ntawm 000 (qhov chaw). Lub tuam txhab kwv yees tias nyob rau hauv 100-5 xyoo tom ntej no, lithium-ion roj teeb yuav ntaus lub lag luam ntawm $ 10 ib kilowatt-teev, txhawb nqa ceev ceev thiab withstands 10 cycles, 000 xyoo ntawm kev ua haujlwm.
Sila Nano yog ib lub tuam txhab pab Mercedes (Daimler) tsim nws tus kheej lithium-ion roj teeb factories.
Qhov no yuav txaus siab rau koj:
