Dab tsi yog qhov txawv ntawm cov roj teeb thiab NMC lithium roj teeb? Qhov twg ntawm lawv yog qhov zoo dua, thiab lub sijhawm twg lawv haum rau? Hniav roj teeb yog ib hom lithium hlau phosphate (LiFePO4) roj teeb, thiab ternary lithium roj teeb yog tag nrho hu ua ternary khoom roj teeb. Feem ntau, nws hais txog kev siv cov nickel cobalt lithium manganese oxide (Li (NiCoMn) O2, NCM) los yog npib tsib xee cobalt aluminium (NCA) ternary roj teeb cathode khoom, thiab qhov feem pua ​​ntawm nickel ntsev, cobalt ntsev thiab manganese ntsev yog kho raws li peb. cov khoom sib txawv.

1, Hniav roj teeb (lithium hlau phosphate) 1635492640186392.jpg Lithium hlau phosphate roj teeb siv lithium hlau phosphate (LiFePO4) raws li cov khoom siv cathode thiab hlau raws li cov khoom siv raw ntawm cov roj teeb rechargeable, nrog tus nqi qis, tsis muaj hlau hnyav thiab tsawg dua ib puag ncig. Dab tsi yog qhov txawv ntawm cov hniav roj teeb thiab ternary lithium ion roj teeb hauv lithium hlau phosphate siv lead ua? “Hniav roj teeb” belongs rau lithium hlau phosphate ion roj teeb. Lithium hlau phosphate ion roj teeb siv lithium hlau phosphate (LiFePO4) raws li cov khoom siv cathode thiab hlau raws li cov khoom siv raw ntawm cov roj teeb rechargeable. Nws muaj qhov zoo ntawm tus nqi qis, tsis muaj hlau hnyav thiab tsis muaj kuab paug ib puag ncig. PO daim ntawv cog lus nyob rau hauv lithium hlau phosphate siv lead ua yog ib daim ntawv cog lus ruaj khov, uas yuav tsis xau thaum khaws cia ntawm xoom ua haujlwm voltage. Kev nyab xeeb yam xws li kub kub los yog overcharge lub sij hawm, them ceev ceev, siab tso zis nyob rau hauv lub hwj chim, tsis nco, lub neej voj voog siab, tsis tshua muaj ultra-low kub yam ntxwv, tsis tshua muaj vibration ceev, tsawg zog, khoom yield thiab sib xws kuj tau nug.

2, Ternary lithium ion roj teeb Ternary lithium-ion roj teeb yog tag nrho hu ua ternary khoom siv roj teeb, uas feem ntau yog hais txog kev siv cov nickel cobalt lithium manganese oxide (Li (NiCoMn) O2, NCM) los yog nickel cobalt txhuas (NCA) ternary roj teeb cathode cov ntaub ntawv , thiab qhov kev faib ua feem ntawm nickel ntsev, cobalt ntsev thiab manganese ntsev yog kho raws li peb yam sib txawv. Lub npe hu ua ternary roj teeb suav nrog ntau yam sib txawv ntawm cov roj teeb rechargeable. Los ntawm cov tsos, nws tuaj yeem muab faib ua cov ntim ntim tau yooj yim, cylindrical rechargeable roj teeb thiab square plhaub rechargeable roj teeb. Nws lub zog nominal yog siab dua li ntawm lub zog, kev ua haujlwm siab ua haujlwm voltage platform, siab vibration ceev, mileage, siab zog thiab kub kev ntseeg siab, tab sis nws muaj zoo heev ultra-low kub yam ntxwv thiab siab project nqi. Qhov zoo thiab qhov tsis zoo ntawm ternary lithium ion roj teeb saum toj no thiab lithium hlau phosphate fais fab lithium roj teeb tuaj yeem raug qhia. Lub ntsiab zoo ntawm lithium ion phosphate roj teeb yog kev nyab xeeb thiab ruaj khov thiab ntev kev pab cuam lub neej ntawm circulating system. Qhov tsis zoo yog cov yam ntxwv tsis zoo ntawm qhov kub thiab txias thiab tsis tshua muaj zog. Txawm li cas los xij, lithium-ion roj teeb tuaj yeem ua kom muaj txiaj ntsig zoo ntawm cov txheeb ze, tab sis nws cov yam ntxwv kub kub tsis zoo. Piv nrog lithium-ion phosphoric acid roj teeb, nws txoj kev nyab xeeb thiab kev ntseeg tau me ntsis tsis zoo. Nrog kev nce ntawm kev lag luam tsheb tshiab lub zog, daim ntawv thov ntawm cov roj teeb rov qab tau dhau los ua ntau dua. Tsis yog txhua tus paub txog cov roj teeb lithium-ion siv hauv tsheb. Txawm tias nyob rau hauv tas li ntawd mus rau lub configuration ntawm ntshiab hluav taws xob tsheb, nws kuj yog ib tug zoo piv txwv nyob rau hauv lwm yam teb, xws li cov xov tooj ntawm tes. Txhua yam yog qhov zoo thiab qhov tsis zoo. Tshaj ib qib kev thov zoo, peb yuav tsum nkag siab nws. Qhov zoo ntawm lithium-ion roj teeb yog tias lawv tsis muaj lub cim xeeb thiab kev ua haujlwm kub ntau. Txawm tias tom qab lub sijhawm ua haujlwm ntev, kev cia siab ntawm cov khoom tuaj yeem khaws cia. Cov roj teeb lithium ion tau muab faib ua lithium ion roj teeb thiab lithium ion roj teeb theem nrab.

3, Kev sib piv zoo thiab qhov tsis zoo ntawm cov roj teeb thiab cov roj teeb lithium ternary Lub roj teeb lithium-ion no hloov tau ntau dua li cov roj teeb uas siv tau, tsim nyog rau kev them nyiaj sai, tuaj yeem khaws ntau dua 80% ntawm lub roj teeb hauv lub sijhawm luv luv, thiab muaj zog polarity. xauv peev xwm. Nws muaj lub zog siab thiab lub roj teeb ntev dua yam tsis muaj kev puas tsuaj rau cov tshuaj. Qhov tsis xws luag ntawm ternary lithium ion roj teeb yog pom tseeb. Tam sim no, feem ntau cov roj teeb lithium-ion ua haujlwm hauv cov kua lossis colloidal systems. Cov duab ntawm ternary lithium-ion roj teeb zoo li no. Nyob rau lub caij ntuj no, vim qhov kub tsis tshua muaj nyob rau sab qab teb, cov kua lossis cov gel hauv cov roj teeb rov qab yuav ua rau qeeb thiab qeeb txawm tias nws tsis coagulate. Qhov cuam tshuam tsis zoo yog tias kev ua haujlwm ntawm cov roj teeb rov qab tau raug txo qis, ua rau lub zog tsis txaus, lub zog tsis txaus thiab txawm tias kaw. Lub taub hau rechargeable roj teeb yog hu ua lithium hlau phosphate rechargeable roj teeb. Nws yog feem ntau hu ua lub taub hau rechargeable roj teeb vim hais tias nws tau muab tso rau hauv lub roj teeb pob zoo li cov hniav. Cov riam lub taub hau thib ob roj teeb muaj zog tiv taus txias dua li ternary lithium-ion roj teeb. Lub lithium ion core muaj tag nrho cov thermal paug cheeb tsam thiab lub zog tshwj xeeb. Cov txheeb ze ntawm cov hniav roj teeb tsis siab dua li ntawm ternary lithium-ion roj teeb, tab sis qhov kev nyab xeeb yog siab dua li ntawm ternary lithium-ion roj teeb. Piv nrog rau qhov tsis ruaj khov ntawm ternary lithium-ion roj teeb, riam disk thib ob roj teeb muaj kev nyab xeeb kev nyab xeeb thiab kev ua haujlwm ntev. Tom qab nyeem tsab xov xwm no, peb pom tias qhov tseeb, cov roj teeb hniav thiab ternary lithium roj teeb muaj lawv tus kheej zoo. Ntxiv rau lawv qhov kev ua tau zoo, lawv cov nqi kuj txawv heev. Yog tias koj xav paub ntau ntxiv txog qhov sib txawv ntawm cov roj teeb hniav thiab ternary lithium roj teeb thiab pab koj xaiv, tiv tauj peb yog qhov kev xaiv zoo dua.
