Cov graphite uas nthuav dav yog ua los ntawm cov flake graphite ntuj, uas tau txais cov khoom zoo thiab tshuaj lom neeg ntawm flake graphite, thiab kuj muaj ntau yam ntxwv thiab cov xwm txheej ntawm lub cev uas flake graphite tsis muaj. Cov graphite uas nthuav dav muaj cov hluav taws xob zoo heev thiab siv dav hauv kev tsim cov khoom siv electrode, thiab yog cov khoom siv roj zoo heev. Tus kws kho graphite Furuite hauv qab no yuav tshuaj xyuas vim li cas cov graphite uas nthuav dav tuaj yeem siv los ua roj teeb:
Nyob rau xyoo tas los no, kev tshawb fawb txog kev nthuav dav graphite ua cov khoom siv roj teeb tau dhau los ua ib qho kev tshawb fawb kub hauv kev tshawb fawb thoob ntiaj teb. Ua cov khoom siv roj teeb, nws siv cov yam ntxwv ntawm lub zog dawb ntawm cov tshuaj tiv thaiv interlayer ntawm cov graphite nthuav dav los hloov mus ua lub zog hluav taws xob, feem ntau nrog cov graphite nthuav dav ua cathode thiab lithium lossis zinc ua anode. Tsis tas li ntawd, kev ntxiv cov graphite nthuav dav rau lub roj teeb zinc-manganese tuaj yeem txhim kho qhov conductivity ntawm lub electrode thiab electrolyte, thiab muab cov khoom zoo heev molding, inhibit qhov yaj thiab deformation ntawm anode, thiab ntev lub neej kev pabcuam ntawm lub roj teeb.
Cov ntaub ntawv carbon feem ntau siv ua cov ntaub ntawv electrode vim lawv cov hluav taws xob conductivity zoo heev. Raws li hom tshiab ntawm nano-scale carbon khoom, nthuav dav graphite muaj cov yam ntxwv ntawm xoob thiab porous, thaj chaw loj thiab kev ua haujlwm siab. Nws tsis tsuas yog muaj kev coj ua zoo thiab adsorption, tab sis kuj muaj kev ruaj khov tshuaj zoo heev, yog li nws yog dav siv hauv cov ntaub ntawv electrode.
Furuite Graphite feem ntau yog koom nrog cov khoom lag luam graphite siab. Muaj ntau ntau yam thiab cov lus qhia ntawm cov graphite nthuav dav. Cov lus qhia tshwj xeeb tuaj yeem hloov kho raws li cov neeg siv khoom xav tau. Cov qauv tuaj yeem xa ntawv. Yog tias koj xav tau, thov hu rau peb.
