Dab tsi yog lithium roj teeb diaphragm

Lub diaphragm ntawm lithium roj teeb yog cov yeeb yaj kiab ntawm qhov zoo thiab qhov tsis zoo ntawm cov roj teeb lithium. Thaum lub roj teeb lithium nqa tawm cov tshuaj tiv thaiv electrolytic, nws tuaj yeem cais cov theem zoo thiab tsis zoo kom tsis txhob cuam tshuam luv luv. Tsis tas li ntawd, nws tuaj yeem ua rau cov ions zoo ntawm cov tshuaj electrolyte dawb. Tus nqi ntawm diaphragm suav txog li 10 feem pua ​​​​ntawm cov nqi ntawm lithium roj teeb. Qhov chaw sab hauv tsev ntawm kev muag khoom lag luam tsis loj, thiab cov nyiaj tau los ntawm theem no yog nyob nruab nrab ntawm 50 feem pua ​​-60 feem pua, uas yog qhov loj tshaj plaws ntawm plaub qhov tseem ceeb raw khoom.

Lub diaphragm belongs rau thaj tsam ntawm cov cuab tam hnyav. Ntawm cov plaub loj raw khoom ntawm lithium roj teeb, qhov project peev tuam txhab muaj peev xwm ntau lawm thiab yuav tsum tau nqis peev ntau ntawm cov cuab tam. Yog li ntawd, tsis yog tsuas yog ib qho kev fortress xwb, tab sis kuj yog kev yuav khoom, kev hloov kho thiab kev teeb tsa ntawm cov tshuab thiab khoom siv feem ntau siv sijhawm 2-3 xyoo. Tsuas yog tom qab lub sijhawm ntev ntawm txoj kab nqes nce siab tuaj yeem ua kom ntseeg tau tias muaj lub fortress zoo li cov khoom lag luam zoo. Tsis tas li ntawd, tus nqi depreciation nyob rau hauv daim teb yog siab dhau lawm, cov txheej txheem txheej txheem yog dhau los lawm, thiab lub peev xwm ntau lawm yog outdated. Nws yog qhov yooj yim heev los hloov los ntawm kev muag khoom, thiab cov lag luam me thiab nruab nrab thiab cov lag luam tshiab tsis tuaj yeem muaj sia nyob. Cov tuam txhab uas muaj qhov zoo ntawm preemptive ua si nyob rau hauv lub sij hawm ntev kev tsim kho vaj tse yuav sau tau zoo tib yam nyob rau hauv cov ntaub ntawv pov thawj ntawm cov neeg muas zaub nyob rau hauv nruab nrab thiab qis dua. Vim tias lub diaphragm muaj kev phom sij heev rau cov yam ntxwv thiab qhov ntsuas kev nyab xeeb ntawm cov roj teeb uas siv tau, lub sij hawm txheeb xyuas lub sij hawm ntawm cov roj teeb rechargeable feem ntau yuav tsum yog 2-3 xyoo. Los ntawm kev nkag mus rau hauv kev lag luam diaphragm mus rau cov khoom loj, nws yuav tsum yog li 4-6 xyoo. Tsis tas li ntawd, cov peev txheej nthuav dav thiab rov ua dua tshiab ntawm kev ua cov thev naus laus zis ua rau qhov zoo ntawm cov tuam txhab ua lag luam ua ntau dua thiab pom tseeb thiab nyuaj rau distort.

Lub diaphragm ntawm lithium roj teeb tuaj yeem muab faib ua hom kev npaj qhuav raws li nws cov txheej txheem npaj cov phaj microporous (ntau cov roj teeb lithium hlau phosphate rechargeable roj teeb). Kev npaj ntub dej thiab ua cov thev naus laus zis (ntau ntawm ternary lithium roj teeb)

Cov txheej txheem ntub dej tag nrho muaj kev nyuaj siab thiab raug. Nws tuaj yeem tau txais cov porosity siab thiab zoo huab cua permeability. Nws tuaj yeem tsim lub diaphragm nrog lub teeb yuag, siab toughness thiab siab efficiency zog txheeb ze ntom. Nws yog qhov yooj yim dua los xav txog qhov yuav tsum tau ua ntawm nruab nrab thiab qis qis ntawm cov roj teeb lithium rau lub teeb yuag, qhov chaw loj thiab kev ua haujlwm siab zog txheeb ze. Yog li ntawd, nrog rau txoj kev loj hlob ntawm cov kev xav tau nce ntxiv rau qhov nruab nrab thiab qis qis ntawm cov khoom siv hluav taws xob lithium roj teeb thiab 3C daim ntawv thov, qhov kev thov rau kev kuaj ntub dej diaphragms tau maj mam dhau ntawm qhov ntsuas qhuav diaphragms, nce los ntawm 40 feem pua ​​​​hauv 16 xyoo mus rau ntau dua. 70 feem pua ​​tam sim no. Tsis tas li ntawd, vim yog siv high-pressure polyethylene nyob rau hauv ntub manufacturing, lub melting point yog tsawg, yog li ntawd lub tshav kub kuj tsis muaj zog, uas kuj yog ib qho teeb meem ntawm ternary roj teeb.
