Vim li cas Automotive roj teeb txhuas cov ntaub ntawv nqa tau tus nqi zoo? To taub txoj ntsiab cai hauv ib tsab xov xwm

Lub lattice qauv ntawm txhuas hlau yog sib txuam nrog qhov loj ntawm lithium ions, ua rau nws yooj yim rau tsim lithium aluminium alloys nrog Li ⁺, yog li ua rau hnyav electrochemical corrosion. Thaum lithium tau muab tso rau hauv Aluminium plhaub ntawm lub roj teeb lithium, nws yuav maj mam tsim cov khoom xws li lithium oxide thiab lithium hydroxide, uas yuav ua rau muaj kev cuam tshuam ntxiv nrog CO ₂ hauv huab cua los tsim cov khoom xws li lithium carbonate, thaum kawg ua rau lub roj teeb tsis ua haujlwm. Los ntawm qhov kev xav ntawm lub peev xwm, lub peev xwm ntawm lithium ntawm txhuas yog li 0.3V (vs Li ⁺ / Li), uas siab dua li 0.01-0.2V ntawm graphite tsis zoo electrode. Yog tias lub peev xwm ntawm Aluminium rooj plaub rau cov khoom siv hluav taws xob tshiab tsawg, nws yuav nyiam ntxig lithium dua li graphite, ua rau lub plhaub tsis tuaj yeem rov qab. Yog li ntawd, nws yog ib qho tsim nyog los tswj cov txhuas lub plhaub muaj peev xwm ntawm cov roj teeb lithium saum toj ntawm lithium insertion peev xwm txhawm rau tiv thaiv corrosion los ntawm cov hauv paus hniav.

Los ntawm qhov kev xav ntawm tus qauv electrode muaj peev xwm, txhuas muaj zog txo qis thiab yooj yim oxidized thiab yaj hauv ib puag ncig electrolyte, tsim cov ntsiab lus corrosion uas cuam tshuam rau cov qauv thiab kev nyab xeeb ntawm cov roj teeb. Txawm li cas los xij, qhov zoo electrode ntawm lithium-ion roj teeb muaj peev xwm ntawm 3V-4.5V lossis siab dua thaum them nyiaj. At this potential, the Lithium battery aluminum case will quickly generate a dense, stable, and insulating aluminum oxide passivation film, which can prevent the shell from continuing to be oxidized and dissolved, achieving long-term stable operation. Qhov ntawd yog hais tias, tso cov txhuas casing ntawm lub roj teeb lithium ntawm lub peev xwm zoo tuaj yeem siv cov nyhuv passivation kom ua tiav kev tiv thaiv tus kheej.

Yog tias LiFePO4 roj teeb pob tsis ua nrog cov electrode zoo, yuav muaj qhov sib txawv ntawm qhov zoo electrode thiab lub plhaub hauv lub roj teeb. Qhov sib txawv muaj peev xwm no yuav ua rau lub zog tsis muaj zog los ntawm cov electrolyte, ua rau cov micro short circuits thiab nws tus kheej tawm, uas yuav txo tau lub roj teeb muaj peev xwm thiab lub voj voog lub neej ntev. Tom qab txuas lub zog tshiab aluminium roj teeb rooj rau qhov zoo electrode equipotential, tsis muaj qhov sib txawv ntawm lub plhaub thiab cov hluav taws xob zoo, uas tuaj yeem txo qis sab hauv thiab sab cuam tshuam, txhim kho cov roj teeb sib xws thiab kev pab cuam lub neej, thiab yooj yim rau kev saib xyuas thiab kev tiv thaiv logic ntawm lub roj teeb tswj system.

Nws yuav tsum tau qhia meej tias lub roj teeb lub plhaub nws tus kheej tsis yog "ua kom muaj txiaj ntsig zoo", tab sis ncaj qha txuas mus rau lub davhlau ya nyob twg zoo ntawm lub roj teeb hauv nws cov qauv tsim, tuav tib lub peev xwm. Qhov kev tsim no ua tiav daws cov teeb meem tseem ceeb xws li lithium tso rau hauv lub plhaub txhuas ntawm lithium roj teeb, electrochemical corrosion, passivation tiv thaiv, thiab muaj peev xwm sib txawv to. Nws tsis tsuas yog leverages qhov zoo ntawm lub teeb yuag aluminium, siab thermal conductivity, molding yooj yim, thiab tus nqi nruab nrab, tab sis kuj ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab lub neej ntev ntawm lub roj teeb. Qhov no kuj yog qhov laj thawj tseem ceeb vim li cas square EV tsheb roj teeb vaj tsev nyob feem ntau siv cov tshuaj no.

Yog hais tias koj xav tau customize los yog muasAutomotive roj teeb aluminium case, thov koj tuaj yeem sab laj thiab sib tham txhua lub sijhawm. Peb yuav muab koj nrog kev txhawb nqa kev tshaj lij thiab cov khoom lag luam daws teeb meem.
