Peb nquag sib tham txog cov roj ntsha lithium los yog cov roj lithium, uas yog npe tom qab cov khoom siv zoo. Raws li peb txhua tus paub, qhov tsis ntawm cov roj teeb ntawm txoj kev zoo tib yam tsis yog tib yam nkaus xwb, thiab cov ntsiab lus nram qab no qhia txog qib theem ntawm cov kev txwv tam sim no. Cov lithium cobalt oxide ( LiCoO2 ), lithium manganate ( LiMn2O4 ), lithium nickel cobalt manganese oxide ( LiNiMnCoO2 los yog NMC ), lithium cobalt txhuas aluminate ( LiNiCoAlO2 los yog NCA ), lithium iron phosphate ( LiFePO4 ), lithium titanate ( Li4Ti5O12 ).
1.Lithium cobalt oxide (LiCoO2)
Lub zog siab ntawm lithium cobalt oxide ua rau nws nyiam xaiv cov xov tooj ntawm tes, phau ntawv sau thiab cov koob yees duab. Lub roj teeb muaj cov cobalt oxide cathode thiab ib qho graphite carbon anode. Lub cathode tau muaj cov qauv hauv qhov lithium ions tsiv ntawm lub anode mus rau lub cathode thaum lub sij hawm paug, thiab cov txheej txheem them cov hluav taws hauv kev tawm tsam.
2.Lithium manganate (LiMn2O4)
Lub peev xwm ntawm lithium manganate yog li ib feem peb qis dua li ntawm lithium cobaltate. Kev tsim yooj yim tso cai rau engineers xaiv lub siab tshaj plaws roj teeb lub neej los yog nce siab tshaj tam sim no (tshwj xeeb kev muaj zog) los yog peev xwm (tshwj xeeb zog)
3.lithium nickel cobalt manganese oxide (LiNiMnCoO2 los yog NMC)
Ntawm daim card ntawm NMC lus dag nyob rau hauv ua ke ntawm nickel thiab manganese. Zoo sib xws rau qhov no yog ntsev, uas cov khoom tseem ceeb hauv cov tshuaj sodium thiab chloride yog cov tshuaj lom, tab sis lawv sib xyaw ua ib lub caij ua ntsev thiab zaub mov. Nickel paub txog nws siab zog tshwj xeeb, tab sis nws txoj kev ruaj ntseg yog pluag; tus manganese spinel qauv muaj peev xwm ncav tsis tau sab hauv tiam sis tsis muaj zog. Ob yam lub cev muaj hlau ua tau zoo dua.
4.lithium cobalt txhuas aluminate (LiNiCoAlO2 los yog NCA)
Nws muaj zog ntau dua, thiab lub hwj chim tshwj xeeb thiab lub neej ntev kev ua haujlwm zoo li NMC. Tsawg tshaj li qhov tsis txaus siab yog kev ruaj ntseg thiab raug nqi. NCA yog ib txoj kev loj hlob ntxiv ntawm lithium nickel oxide; qhov ntxiv ntawm txhuas muab cov roj teeb zoo dua qub rau sawv daws.
5. phosphorus hlau phosphate (LiFePO4)
Lithium phosphate muaj cov khoom siv hluav taws xob zoo thiab tsis muaj hluav taws xob ua haujlwm. Qhov no yog tiav los ntawm cov khoom nanoscale phosphate cathode. Qhov zoo tshaj plaws yog qhov kev ntsuam xyuas siab thiab kev ua neej ntev ntev; zoo thermal stability, kev nyab xeeb kom zoo thiab kam rau ua phem.
6.lithium titanate (Li4Ti5O12)
LTO (feem ntau Li4Ti5 O12) muaj xoom lim, tsis muaj SEI zaj duab xis thiab tsis muaj lithium plating thaum lub sij hawm sai thiab kub tsis tau them, yog li muaj zoo dua thiab paug kev kawm tshaj cov pa cob co zoo li Li-ion thiab graphite anodes. Lub thermal stability ntawm kev kub muaj peev xwm kuj zoo dua li lwm cov lithium ion systems; Txawm li cas los xij, roj teeb yog kim. Lub zog tshwj xeeb tsawg, tsuas yog 65Wh / kg, uas yog sib npaug rau NiCd. Lithium titanate tau them rau 2.80 V thiab qhov kawg ntawm qhov paug yog 1.80 V.
Yog tias koj xav ua ib qho ntawm cov roj teeb saum toj saud, peb tuaj yeem muab koj cov khoom raw rau cov roj teeb no.
