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