Lithium Metal Composite Anode Materials tuaj yeem Ua Rau Lub Zog Muaj Zog Ntawm Lithium Roj Teeb, Nrog Chav Loj Rau Kev Txhim Kho Yav Tom Ntej

Hlau lithium tuaj yeem siv ncaj qha ua cov khoom siv hluav taws xob tsis zoo, tab sis muaj peev xwm ua rau muaj kev nyab xeeb. Thaum lub sij hawm rov siv tau ntev, teeb meem xws li ntim nthuav dav thiab lithium dendrite kev loj hlob yuav tshwm sim. Kev nthuav dav ntim yuav ua rau cov qauv hluav taws xob tawg, thiab kev loj hlob ntawm lithium dendrites yuav hla lub roj teeb cais thiab ua rau lub roj teeb. Luv Circuit Court.

Hauv lub roj teeb lithium, qhov hluav taws xob tsis zoo ua lub luag haujlwm oxidizing thiab yog tus ncej uas cov hluav taws xob ntws tawm hauv Circuit Court. Cov khoom siv hluav taws xob tsis zoo yog cov khoom siv uas ua rau cov hluav taws xob tsis zoo, thiab nws qhov ua tau zoo cuam tshuam ncaj qha rau lub zog ntom ntom ntawm cov roj teeb lithium. Muaj ntau hom ntaub ntawv uas tuaj yeem siv rau qhov tsis zoo electrodes, feem ntau yog tseem nyob rau theem kev tshawb fawb. Tam sim no, cov khoom siv hluav taws xob tsis zoo feem ntau hauv cov roj teeb lithium yog cov khoom siv carbon xws li cov khoom siv ntuj tsim/khoom cua. Cov hlau lithium sib xyaw cov khoom siv anode muaj qhov zoo ntawm qhov muaj peev xwm tshwj xeeb tshwj xeeb thiab muaj peev xwm siv hluav taws xob tsawg heev. Nws tuaj yeem siv rau hauv cov roj teeb lithium kom ua rau lub zog ceev ntawm cov roj teeb lithium ntau heev. Nws yog yam tshiab ntawm cov khoom siv anode.

Kev koom ua ke ntawm cov neeg siv khoom siv hluav taws xob txuas ntxiv mus ntxiv, kev siv hluav taws xob txuas ntxiv mus, thiab nws cov ntim txuas ntxiv zuj zus, thiab cov kev xav tau rau lithium roj teeb lub zog ntom txuas ntxiv mus; kev ua siab ntev ntawm cov tsheb hluav taws xob ntshiab yog ib qho tseem ceeb uas txwv kev nce nrawm hauv nws daim ntawv thov nkag mus. Kev lag luam tsheb tshiab muaj zog xav tau sai rau cov roj teeb lithium-high-energy-density. Cov hlau lithium sib xyaw cov khoom siv anode muaj qhov siab theoretical tshwj xeeb muaj peev xwm thiab tsis tshua muaj hluav taws xob muaj peev xwm. Nws yog cov khoom siv anode zoo tshaj plaws rau lub zog muaj zog ceev lithium roj teeb. Nws cia siab tias yuav hloov cov khoom siv graphite yav tom ntej, thiab kev ua lag luam muaj chav loj rau kev txhim kho.

Raws li" Kev Tshawb Fawb Txog Kev Lag Luam thiab Kev nqis peev Cov Tswv Yim Pom Zoo Qhia Txog Cov Hlau Lithium Composite Anode Material Industry rau 2021-2025&"; Tshaj tawm los ntawm Lub Sijie Tshiab Kev Tshawb Fawb Kev Tshawb Fawb, kuv lub tebchaws' cov khoom lag luam anode yuav txuas ntxiv mus los ntawm 2015 txog 2020, nrog qhov nruab nrab txhua xyoo kev loj hlob. Ntau tshaj 30%; xyoo 2020, kuv lub tebchaws' cov khoom siv anode xa khoom yuav yog txog 370,000 tons. Nyob rau theem no, hauv kuv lub tebchaws' cov khoom lag luam anode, cov khoom siv graphite thiab cov graphite ntuj nyob hauv txoj haujlwm tseem ceeb. Yog tias cov hlau lithium sib xyaw cov khoom siv anode tuaj yeem hloov cov khoom siv graphite yav tom ntej, muaj chav dav rau kev txhim kho.

Kev npaj cov txheej txheem ntawm cov hlau lithium sib xyaw cov khoom siv anode feem ntau suav nrog: siv cov txheej txheem tshuaj tiv thaiv hauv qhov chaw los npaj cov roj teeb lithium nitride (Li3N); siv magnetron sputtering txoj hauv kev tso aC nano zaj duab xis rau ntawm cov hlau lithium; siv txoj hauv kev nqus pom, Hydrazine hydrate txo qis, khoos phis tawj compaction thiab lwm yam txheej txheem los npaj rGO/Li cov khoom siv anode sib xyaw; siv 3D cov ntaub ntawv los ua tus nqa khoom, cov hlau uas muaj hlau yaj tau txhaj rau hauv cov ntaub ntawv 3D kom tau txais cov khoom sib xyaw anode, thiab lwm yam.

Hlau lithium tuaj yeem siv ncaj qha ua cov khoom siv hluav taws xob tsis zoo, tab sis muaj peev xwm ua rau muaj kev nyab xeeb. Thaum lub sij hawm rov siv tau ntev, teeb meem xws li ntim nthuav dav thiab lithium dendrite kev loj hlob yuav tshwm sim. Kev nthuav dav ntim yuav ua rau cov qauv hluav taws xob tawg, thiab kev loj hlob ntawm lithium dendrites yuav hla lub roj teeb cais thiab ua rau lub roj teeb. Luv Circuit Court. Cov xwm txheej no txwv kev siv cov hlau lithium ua cov khoom siv hluav taws xob tsis zoo. Cov khoom siv roj ntsha lithium tsis zoo tuaj yeem daws cov teeb meem no tau zoo, yog li nws cov kev tshawb fawb txuas ntxiv mus tob dua.

Cov kws tshuaj ntsuam xyuas kev lag luam hauv Kev Xav Tshiab tau hais tias xyoo 2021, tsoomfwv Suav yuav teev cov khoom siv hluav taws xob muaj zog ntau-lithium hlau raws cov roj teeb thib ob thiab lawv cov ntaub ntawv tseem ceeb ua cov khoom tshwj xeeb tseem ceeb ntawm&"high-end functional and smart materials&] & quot;, thiab tawm tswv yim txog kev tshawb fawb yooj yim ntawm kev kawm hlau lithium-based cov roj teeb thib ob Cov teeb meem, cov ntaub ntawv tseem ceeb thiab thev naus laus zis. Tsav los ntawm txoj cai hauv tebchaws, kev nrawm ntawm kev tshawb fawb txuj ci ntawm lithium hlau sib xyaw cov khoom siv anode hauv kuv lub tebchaws thiab kev tsim khoom lag luam ntawm kev tshawb fawb tau cia siab tias yuav nrawm dua.

Xinsijie Kev Tshawb Fawb Kev Tshawb Fawb Lub Tsev Xinsijie tau cog lus los ua qhov kev tshawb fawb kev lag luam zoo tshaj plaws, thiab tau tsim cov txheej txheem kev lag luam nyob hauv tsev tsom mus rau kev tshawb fawb kev lag luam, kev tshawb fawb kev lag luam, phiaj xwm thiab kev sab laj, thiab lwm yam, nrog kev tshawb fawb kev lag luam nyob txawv teb chaws, tuam txhab lag luam txawv teb chaws qhov chaw thiab sau npe, thiab lwm yam. Lub hauv paus tseem ceeb ua lag luam nyob txawv teb chaws muab cov neeg siv khoom nrog ntau yam ntawm kev lag luam sab hauv thiab txawv teb chaws kev pab tswv yim.
