Lub zog tshiab lub tsheb lithium anode khoom muajtungsten oxide WO3 nanoparticles.

Hauv kev tsim cov tsheb fais fab tshiab, kev siv cov khoom siv lithium anode uas muaj cov tungsten oxide daj tuaj yeem muab lub zog rau lub zog roj teeb thiab txhim kho cov nqi ntawm lub tsheb.
Raws li kev lag luam tsheb tshiab muaj kev txhawj xeeb, lub roj teeb ib feem yog lub hauv paus ntawm peb lub tshuab hluav taws xob.Raws li cov neeg ua haujlwm cuam tshuam, hauv 2019, thawj pawg ntawm lub zog tshiab lub tsheb roj teeb lub zog ceev ntawm 160Wh / Kg lossis ntau dua. , tag nrho ntawm 15 qauv, raws li BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri.Lub roj teeb tshuab lawv tsim yog tag nrho raws li ternary roj teeb. Cov kws tshaj lij taw qhia. hais tias nyob rau hauv cov txheej txheem ntawm lithium anode cov ntaub ntawv, ntxiv nano daj tungsten oxide yuav ua rau lub roj teeb muaj ib tug ntau dua nqi kev ua tau zoo, thiab ces txhim kho cov kev sib tw ntawm lub zog tshiab tsheb nyob rau hauv lub thoob ntiaj teb kev ua lag luam.Qhov laj thawj yog vim li cas daj nano-loj tungsten oxide hais. siv lithium anode cov ntaub ntawv yog tias daj tungsten oxide muaj qhov zoo ntawm lub zog ntau dua thiab tus nqi qis dua.

Nano daj tungsten trioxide, WO3 hmoov, yog ib qho tshwj xeeb inorganic N-hom semiconductor khoom, uas tuaj yeem siv los npaj cov khoom siv hluav taws xob zoo, uas yog, kev npaj ceev ceev them lithium roj teeb tsis tau tsuas yog cov khoom siv hluav taws xob ntau dua, tab sis kuj txo cov nqi tsim khoom.Piv nrog cov roj teeb zoo sib xws hauv kev lag luam, cov roj teeb lithium uas muaj nanometer tungsten hmoov muaj ntau yam kev siv, thiab tuaj yeem muab lub zog txaus rau lub zog tshiab, cov cuab yeej hluav taws xob, lub xov tooj ntawm tes kov, laptops thiab lwm yam khoom siv.

Ternary Lithium roj teeb thiab Lithium Iron phosphate roj teeb txhim kho cov kev ua kom zoo nkauj.

Kev tsim kho thev naus laus zis ntawm cov khoom siv lithium cathode

Orthosilicate, txheej lithium-nplua nuj manganese-raws li, sulfide-raws li cathode cov ntaub ntawv yog cov kev tshawb fawb kub tam sim no.Hauv txoj kev xav, orthosilicate tuaj yeem tso cai rau kev sib pauv ntawm 2 Li +, uas muaj lub peev xwm theoretical siab, tab sis hauv cov txheej txheem tso tawm, lub peev xwm tiag tiag. tsuas yog ib nrab ntawm lub peev xwm theoretical.Ntxiv rau lub zog tshwj xeeb, txheej lithium nplua nuj manganese puag muaj qhov zoo ntawm tus nqi tsim nyog.Ua ntej qhov no, nws yog ib qho tsim nyog yuav tsum nrhiav txoj kev tsim khoom tsim nyog.Sulphur-based cathode cov ntaub ntawv muaj lub zog ntom ntom ntawm 2600Wh / kg, tab sis qhov ntim nthuav dav yog qhov yooj yim tshwm sim hauv cov txheej txheem them thiab tawm, uas yuav tsum tau txhim kho.
Kev tsim kho thev naus laus zis ntawm lithium anode cov ntaub ntawv

Graphene, lithium titanate thiab nano daj tungsten oxide yog cov khoom siv lithium anode zoo tshaj plaws.Graphene tuaj yeem siv los ua tus neeg sawv cev tsis zoo los ua cov khoom sib xyaw nrog cov khoom zoo thiab tsis zoo, tab sis nws tsis tuaj yeem siv ntau ntau los ua cov khoom siv los hloov graphite. cov khoom siv anode.Lithium titanate muaj lub neej voj voog ntev, mus txog ntau dua 10,000 zaug, thiab tuaj yeem them sai sai, haum rau qhov chaw tsis tas yuav tsum muaj lub zog cia.Nano daj tungsten oxide yog cov khoom siv hluav taws xob tshwj xeeb nrog lub peev xwm theoretical ntawm 693mAh / g thiab kev ua haujlwm zoo electrochromic.Tsis tas li ntawd, nws muaj qhov zoo ntawm tus nqi qis, ntau reserves thiab non-toxicity.

Hauv kev xaus, nano-loj tungsten oxide WO3 tuaj yeem siv los ua cov khoom siv hluav taws xob thiab siv hauv tsheb tshiab.

Guangzhou Hongwu Material Technology Co., Ltd. yog muabNano daj tungsten trioxide WO3nyob rau hauv tej, nrog ib lub hlis tso zis ntau tshaj 2 tons.Tsav los ntawm lub zog tshiab tsheb, peb maj mam nthuav cov kab ntau lawm, muab cov khoom zoo dua rau kev ua lag luam, thiab ua kom muaj kev sib haum xeeb rau lub zog tshiab.
