Lub zog tshiab hluav taws xob tsheb tau nce zuj zus los ua thawj qhov kev xaiv rau ntau tus neeg yuav tsheb.Lawv yog cov ntse dua thiab kev lag luam ntau dua li roj tsheb, tab sis cov roj teeb tseem yog qhov teeb meem loj, xws li roj teeb lub neej, qhov ceev, qhov hnyav, tus nqi thiab kev nyab xeeb.Qhov tseeb, muaj ntau hom roj teeb fais fab.Hnub no, kuv yuav tham nrog koj txog ntau hom roj teeb lub zog tshiab tam sim no.
Yog li, cov roj teeb fais fab tam sim no feem ntau suav nrog hom hauv qab no, xws li ternary lithium roj teeb, lithium hlau phosphate roj teeb, lithium cobalt oxide roj teeb, nickel hlau hydride roj teeb, thiab cov roj teeb hauv lub xeev.Ntawm lawv, lub zog tshiab trams feem ntau siv ternary lithium roj teeb thiab lithium hlau phosphate roj teeb, uas yog lub npe hu ua "ob tus phab ej sib tw rau hegemony".
Ternary lithium roj teeb: Qhov zoo ib yam yog nickel-cobalt-manganese series ntawm CATL.Tseem muaj cov nickel-cobalt-aluminium series hauv kev lag luam.Nickel ntxiv rau lub roj teeb kom lub roj teeb muaj peev xwm khaws cia thiab txhim kho roj teeb lub neej.
Nws yog tus cwj pwm los ntawm qhov me me, lub teeb yuag, lub zog siab ntom ntom, txog 240Wh / kg, tsis zoo thermal stability, thiab ntau dua rau cov teeb meem combustion.Nws yog resistant rau tsis kub tab sis tsis mus rau high kub.Qhov kev txwv qis ntawm kev siv kub tsawg yog rho tawm 30 ° C, thiab lub zog yog attenuated li ntawm 15% thaum lub caij ntuj no.Qhov kub ntawm qhov cua sov yog nyob ib ncig ntawm 200 ° C-300 ° C, thiab qhov kev pheej hmoo ntawm kev sib tsoo tshwm sim yog siab.
Lithium hlau phosphate roj teeb: hais txog lub roj teeb lithium-ion siv lithium hlau phosphate ua cov khoom siv electrode zoo thiab carbon raws li cov khoom tsis zoo electrode.Piv nrog ternary lithium roj teeb, nws cov thermal stability zoo dua thiab nws cov nqi tsim khoom qis dua.Ntxiv mus, lub neej voj voog ntawm lithium hlau phosphate roj teeb yuav ntev dua, feem ntau 3,500 zaug, thaum ternary lithium roj teeb feem ntau pib lwj ib ncig ntawm 2,000 zaus ntawm kev them nqi thiab tawm.
Lithium cobalt oxide roj teeb: Lithium cobalt oxide roj teeb kuj yog ib ceg ntawm lithium-ion roj teeb.Lithium cobalt oxide roj teeb muaj cov qauv ruaj khov, muaj peev xwm sib piv thiab kev ua haujlwm zoo heev.Txawm li cas los xij, cov roj teeb lithium cobalt oxide muaj kev nyab xeeb tsis zoo thiab tus nqi siab.Lithium cobalt oxide roj teeb feem ntau yog siv rau cov roj teeb me me thiab nruab nrab.Lawv yog cov roj teeb ntau hauv cov khoom siv hluav taws xob thiab feem ntau tsis siv hauv tsheb.
Nickel-hlau hydride roj teeb: Nickel-hlau hydride roj teeb yog ib hom tshiab roj teeb ntsuab tsim nyob rau hauv 1990s.Nws muaj cov yam ntxwv ntawm lub zog siab, lub neej ntev, thiab tsis muaj kuab paug.Cov electrolyte ntawm nickel-hlau hydride roj teeb yog cov tshuaj uas tsis yog-flammable potassium hydroxide, yog li txawm tias muaj teeb meem xws li roj teeb luv luv tshwm sim, feem ntau nws yuav tsis ua rau muaj kev sib tsoo.Kev nyab xeeb yog lav thiab cov txheej txheem tsim khoom yog paub tab.
Txawm li cas los xij, kev them nqi hluav taws xob ntawm nickel-hlau hydride roj teeb yog qhov nruab nrab, tsis tuaj yeem siv lub zog hluav taws xob ceev ceev, thiab nws qhov kev ua tau zoo dua li ntawm lithium roj teeb.Yog li ntawd, tom qab kev siv ntau ntawm cov roj teeb lithium, cov roj teeb nickel-hlau hydride kuj tseem yuav maj mam hloov.
