Ntchito za PTFE High-Temperature Fabric mu Lithium Battery Industry

Monga gwero wopanga PTFE mkulu-kutentha nsalu, Jiangsu Aokai New Materials amakupatsirani chidziwitso chaukadaulo. Pakupanga batire ya lithiamu, nsalu ya PTFE yotentha kwambiri imagwiritsidwa ntchito makamaka kuti itetezedwe, kudzipatula komanso kutumiza munjira zazikuluzikulu chifukwa cha kukana kwake kutentha kwambiri, kusakhazikika kwamankhwala ndi katundu wosagwira ndodo. Kukaniza kwake ku dzimbiri kwa electrolyte kumaphatikizapo zofunikira kwambiri zamafakitale kuposa kukana kwa dzimbiri.

Ntchito Yoyambira 1: Electrode Production ndi Cell Assembly

Popanga maelekitirodi a batri ndi njira zolumikizira ma cell, nsalu ya PTFE yotentha kwambiri imagwiritsidwa ntchito kwambiri potumiza, kuteteza komanso kudzipatula kotentha.

Electrode Drying Conveyor Belt  Imagwira ntchito ngati lamba wotumizira panthawi yakutentha kwambiri kwa ma elekitirodi abwino komanso oyipa pa 120 ℃ ~ 180 ℃. Mphamvu yake yotsika kwambiri imalepheretsa kumamatira kwa zida za ternary, graphite ndi ma slurries ena, kupewa kuipitsidwa ndi kuwonongeka kwa zokutira zama elekitirodi.

Kusindikiza kwa Cell Hot Press  Ndi makulidwe wamba a 0.18 mm, imakhala ngati gawo lodzipatula komanso chitetezo pakati pa mutu wotentha ndi cell thumba posindikiza kutentha. Kugonjetsedwa ndi kutentha pamwamba pa 240 ℃, kumatsimikizira kutentha kwa yunifolomu, kumalepheretsa kumamatira komanso kumawonjezera zokolola.

Kuwotcherera kwa Tab ndi Kuteteza Kumakani Otentha  Kumagwiritsidwa ntchito ngati zotchingira ndi kudzipatula pakuwotcherera tabu ndikukanikiza kotentha pafupifupi 200 ℃. Pokhala ndi kutsekemera kwakukulu kokhala ndi dielectric yosasintha pansi pa 2.6, imapewa bwino mabwalo afupikitsa, imalimbana ndi nthunzi ya electrolyte, ndipo imalepheretsa kukana kowonjezereka chifukwa cha dzimbiri ndi makutidwe ndi okosijeni a tabu zamkuwa / aluminiyamu.

Ntchito Yoyambira 2: Msonkhano wa Battery Pack ndi Chitetezo cha System

Pamsonkhano wa batri pack, imayang'ana kwambiri chitetezo chamagetsi ndi kasamalidwe kamafuta.

Kudzipatula Kwapakati Pakati pa Maselo  Kuyika pakati pa maselo amodzi, kumapereka kutsekemera kwabwino kwambiri ndi kutentha kwa moto mpaka ku UL94 V-0 kalasi , kuteteza maulendo afupikitsa ndi kufalikira kwa kutentha kwa kutentha.

Mawaya a M'kati ndi Chitetezo Chachigawo  Amakulunga mawaya apamwamba kwambiri ndi zolumikizira kuti apereke kutentha kwapamwamba komanso kusindikiza, kupewa maulendo afupiafupi omwe amayamba chifukwa cha dzimbiri la electrolyte.

Thermal Management System Auxiliary Material  Ndi osiyanasiyana kutentha kukana kwa -196 ℃ ~ 300 ℃  ndi controllable matenthedwe madutsidwe, ntchito ngati mfundo m'munsi pa kutentha kutchinjiriza gaskets ndi mapepala matenthedwe conductive kulinganiza kutentha mkati batire mapaketi.

Kusindikiza Kwa Battery Pack Yonse  Kumagwiritsidwa ntchito posindikiza nyumba ya batri, kumakana kulowa kunja kwa chinyezi ndi dzimbiri kuchokera ku kutuluka kwakung'ono kwa electrolyte mkati.

Chofunikira Chapadera 1: Kukaniza Kwabwino Kwambiri Pazinthu Zosiyanasiyana za Electrolyte

Lithium batire electrolyte ndi zowononga kwambiri, kotero kukana mankhwala ndi chizindikiro chofunika kwambiri cha PTFE mkulu kutentha nsalu:

Organic Solvents  Zigawo zazikulu za electrolyte monga Ethylene Carbonate (EC) ndi Dimethyl Carbonate (DMC) ndi zosungunulira zamphamvu za polar. Mapulasitiki wamba adzatupa kapena kusungunuka atawululidwa, pomwe PTFE imakhalabe yosakhudzidwa.

Corrosive Electrolytes  Lithium Hexafluorophosphate (LiPF₆), mchere wapakati wa electrolyte, umamva chinyezi komanso kutentha ndipo umawola mosavuta kuti upange Hydrofluoric Acid (HF). HF imawononga kwambiri ndipo imatha kuwononga magalasi ndi zitsulo zambiri. Nsalu ya PTFE yotentha kwambiri imapereka kukana kwambiri kwa hydrofluoric acid ndikusunga magwiridwe antchito m'malo ovuta.

Kukhazikika kwa Electrochemical  Pansi pa ma voliyumu apamwamba komanso kutulutsa-charge-charge yogwira ntchito mkati mwa mabatire, PTFE imakhala ndi zinthu zokhazikika zamakemikolo, zomwe sizipanga mbali ndi electrolyte komanso palibe kuwonongeka kwa electrolyte.

Salt Spray Corrosion Resistance  Electrolyte kutayikira kumapanga utsi wonyezimira wamchere, pomwe nsalu ya PTFE yotentha kwambiri imawonetsa kulolerana kwambiri.

Chofunikira Chapadera 2: Kukumana ndi Magwiridwe Okhwima a Battery

Zapamwamba zakuthupi ndizofunika; Kukhazikika kwanthawi yayitali m'malo enieni a batri kuyenera kuyesedwa mwamphamvu:

Mayeso Okalamba a Electrolyte  Iyi ndiye njira yotsimikizika kwambiri komanso yovuta kwambiri. Zitsanzo zimamizidwa mu electrolyte yofananira ndikusungidwa kwa masiku kapena masabata kutentha kwa chipinda kapena kutentha kwapamwamba monga 60 ℃ ndi 85 ℃. Zogulitsa zoyenerera sizimawonetsa kuphulika, delamination kapena kusungunuka ndi kuchepa thupi kwambiri.

Mwachidule, nsalu ya PTFE yotentha kwambiri imakhala ngati chophimba choteteza, chotchinga chodzipatula komanso kutumiza sing'anga pakupanga batire la lithiamu. Kaya kupirira dzimbiri la electrolyte mkati mwa maselo kapena kupereka chitetezo chokhazikika pakutentha kwambiri monga kukanikiza ndi kuwotcherera, ntchito yake yodalirika ndiyofunikira kuti zitsimikizire zokolola, chitetezo chogwira ntchito komanso moyo wautali wa mabatire a lithiamu.

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna kuphunzira mwatsatanetsatane za luso lazigawo, zochitika zamagwiritsidwe ntchito ndi mayankho makonda amtundu wathu wonse, kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi yomatira ya PTFE, lamba wotentha kwambiri wa PTFE, lamba wamakina osakanizika, mbali imodzi ya PTFE yokutidwa, nsalu yotchinga ndi magalasi apamwamba, chonde osamva kutentha kwa magalasi, chonde musakane. tiuzeni kudzera:
