Kev Taw Qhia:
Cov roj teeb lithium tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub, muab zog rau txhua yam los ntawm cov xov tooj ntse thiab cov laptops mus rau cov tsheb fais fab thiab cov tshuab khaws cia hluav taws xob. Ntawm ntau hom roj teeb lithium hauv khw, ob txoj kev xaiv nrov yog cov roj teeb lithium hlau phosphate (LiFePO4) thiab cov roj teeb lithium ternary. Kev nkag siab txog qhov sib txawv ntawm ob hom roj teeb lithium no yog qhov tseem ceeb rau kev txiav txim siab paub thaum xaiv qhov chaw fais fab zoo rau ib qho kev siv tshwj xeeb.
Lub roj teeb lithium hlau phosphate (LiFePO4)
Lub roj teeb Lithium hlau phosphate, tseem hu ua LFP roj teeb, yog lub roj teeb lithium-ion uas siv tau dua los ntawm kev siv lithium hlau phosphate ua cov khoom siv cathode. Cov roj teeb no paub txog lawv lub zog ceev ceev, lub neej ntev, thiab kev ruaj khov zoo heev ntawm thermal thiab tshuaj lom neeg. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm LiFePO4 roj teeb yog lawv txoj kev nyab xeeb, vim tias lawv tsis tshua muaj kev kub ntxhov thiab tiv taus kev them ntau dhau thiab luv luv dua li lwm hom roj teeb lithium.
Lub roj teeb lithium peb txheej
Lub roj teeb lithium ternary, ntawm qhov tod tes, yog lub roj teeb lithium-ion uas siv cov khoom sib xyaw ua ke ntawm nickel, cobalt, thiab manganese hauv cov khoom siv cathode. Cov hlau sib xyaw ua ke no ua rau cov roj teeb lithium ternary ua tiav qhov ceev zog thiab lub zog tso zis ntau dua piv rau cov roj teeb lithium hlau phosphate. Cov roj teeb lithium ternary feem ntau siv rau hauv cov tsheb fais fab thiab cov ntawv thov fais fab siab, qhov twg qhov ceev zog thiab kev them ceev yog qhov tseem ceeb.
Qhov sib txawv tseem ceeb:
1. Lub zog ceev:Ib qho ntawm qhov sib txawv tseem ceeb ntawm lithium iron phosphate thiab ternary lithium roj teeb yog lawv lub zog ceev. Ternary lithium roj teeb feem ntau muaj lub zog ceev dua, uas txhais tau tias lawv tuaj yeem khaws cia ntau lub zog hauv tib lub ntim lossis qhov hnyav dua li lithium iron phosphate roj teeb. Qhov no ua rau ternary lithium roj teeb zoo tagnrho rau cov ntawv thov uas xav tau lub zog cia siab, xws li tsheb fais fab thiab cov khoom siv hluav taws xob nqa tau.
2. Lub neej voj voog:Cov roj teeb lithium iron phosphate paub txog lawv lub neej ntev thiab muaj peev xwm tiv taus ntau lub sijhawm them thiab tso tawm yam tsis muaj kev puas tsuaj loj heev. Qhov sib txawv, txawm hais tias cov roj teeb lithium ternary muab lub zog ceev dua, lawv lub neej voj voog yuav luv dua piv rau cov roj teeb lithium iron phosphate. Qhov sib txawv ntawm lub neej voj voog yog qhov tseem ceeb xav txog thaum xaiv lub roj teeb rau kev siv mus sij hawm ntev thiab kev ruaj khov.
3. Kev Nyab Xeeb: Rau cov roj teeb lithium, kev nyab xeeb yog qhov tseem ceeb. Cov roj teeb Lithium hlau phosphate raug suav hais tias muaj kev nyab xeeb dua li cov roj teeb lithium ternary vim lawv qhov ruaj khov thiab tiv taus thermal runaway. Qhov no ua rau cov roj teeb LiFePO4 yog thawj qhov kev xaiv rau kev siv kev nyab xeeb ua ntej xws li cov txheej txheem khaws cia hluav taws xob thiab kev thaub qab hluav taws xob ruaj khov.
4. Tus nqi: Piv nrog cov roj teeb lithium iron phosphate, tus nqi tsim khoom ntawm cov roj teeb lithium ternary feem ntau siab dua. Tus nqi siab dua yog vim siv nickel, cobalt thiab manganese hauv cov ntaub ntawv cathode, nrog rau cov txheej txheem tsim khoom nyuaj uas xav tau kom ua tiav qhov ceev ntawm lub zog thiab lub zog tso zis. Qhov sib txawv, cov roj teeb lithium iron phosphate paub txog lawv cov nqi tsim nyog, ua rau lawv yog qhov kev xaiv nrov rau cov ntawv thov uas tus nqi ua lub luag haujlwm tseem ceeb hauv cov txheej txheem txiav txim siab.
Xaiv lub roj teeb uas haum rau koj cov kev xav tau
Thaum xaiv cov roj teeb lithium iron phosphate thiab cov roj teeb lithium ternary, yuav tsum xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov uas xav tau. Rau cov ntawv thov uas muaj kev nyab xeeb, lub neej ntev thiab kev siv nyiaj tsim nyog yog qhov tseem ceeb, cov roj teeb lithium iron phosphate yuav yog thawj qhov kev xaiv. Ntawm qhov tod tes, rau cov ntawv thov uas xav tau lub zog ceev ceev, lub peev xwm them ceev ceev, thiab lub zog tso zis siab, cov roj teeb lithium ternary yuav yog qhov kev xaiv zoo dua.
Hauv kev xaus lus, ob lub roj teeb lithium hlau phosphate thiab cov roj teeb lithium peb hom muaj cov txiaj ntsig tshwj xeeb thiab tau tsim los ua kom tau raws li cov kev xav tau sib txawv. Kev nkag siab txog qhov sib txawv ntawm ob hom roj teeb lithium no yog qhov tseem ceeb rau kev xaiv lub zog kom raug uas ua tau raws li cov kev xav tau tshwj xeeb ntawm daim ntawv thov. Thaum thev naus laus zis txuas ntxiv mus, thev naus laus zis roj teeb lithium yuav tsum txhim kho ntxiv, muab ntau txoj kev xaiv rau kev daws teeb meem khaws cia hluav taws xob zoo thiab ruaj khov.
