Izicelo ze-PTFE High-Temperature Fabric ku-Lithium Battery Industry

Njengomkhiqizi womthombo wendwangu ye-PTFE ephezulu yokushisa, I-Jiangsu Aokai New Materials ikunikeza isingeniso esiphrofeshinali. Ekwenziweni kwebhethri ye-lithium, indwangu ye-PTFE enezinga eliphezulu lokushisa isetshenziswa kakhulukazi ukuze kuvikelwe, ihlukaniselwe futhi idluliselwe ezinqubweni ezibalulekile ngenxa yokumelana kwayo nezinga lokushisa eliphezulu, ukungabi namakhemikhali kwamakhemikhali kanye nempahla engelona induku. Ukumelana kwayo nokugqwala kwe-electrolyte kuhilela izidingo zezimboni eziqine kakhulu kunokumelana nokugqwala okulula.

Ukusetshenziswa Okubalulekile 1: Ukukhiqizwa Kwe-Electrode kanye Nomhlangano Weseli

Ekwenziweni kwama-electrode ebhethri nezinqubo zokuhlanganisa amaseli, indwangu ye-PTFE enezinga eliphezulu lokushisa isetshenziswa kabanzi ukudlulisa, ukuvikela kanye nokuhlukaniswa ngokucindezela okushisayo.

I-Electrode Drying Conveyor Belt  Isebenza njengebhande lokudlulisa ngesikhathi somiswa kwezinga lokushisa eliphezulu lama-electrode aqondile noma angalungile ku-120℃~180℃. Amandla ayo aphansi avimbela ukunamathela kwezinto ze-ternary, i-graphite nezinye i-slurries, ukugwema ukungcoliswa kanye nokulimala kwezingubo ze-electrode.

I-Cell Hot Press Sealing  Ngobukhulu obujwayelekile obungu-0.18 mm, isebenza njengesendlalelo esihlukanisayo nesivikelayo phakathi kwekhanda elicindezelayo elishisayo neseli yesikhwama ngesikhathi sokuvalwa okushisayo. Imelana namazinga okushisa angaphezu kuka-240 ℃, iqinisekisa ukudluliswa kokushisa okufanayo, ivimbela ukunamathela futhi ithuthukise isivuno sokupakisha.

I-Tab Welding kanye nokuvikelwa kwe-Hot Press  Isetshenziswa njengokuvikela nokuhlukanisa phakathi kwethebhu yokushisela nokucindezela okushisayo cishe ku-200℃. Ifaka ukufakwa okuphezulu kwe-dielectric okungaguquki ngaphansi kuka-2.6, igwema ngokuphumelelayo izifunda ezimfushane, imelana nomhwamuko we-electrolyte, futhi ivimbela ukumelana nokwanda okubangelwa ukugqwala kanye ne-oxidation yamathebhu ethusi/i-aluminium.

Uhlelo 2 Oluyisisekelo: Ukuhlanganisa Iphakethe Lebhethri Nokuvikelwa Kwesistimu

Ekuhlanganiseni kwephakethe lebhethri, igxile ekuphepheni kukagesi kanye nokuphathwa kwe-thermal.

I-Insulation Isolation Phakathi Kwamaseli  Abekwe phakathi kwamaseli ngamanye, inikeza ukufakwa kwe-insulation okuhle kakhulu kanye ne-flame retadancy kuze kufike ku- UL94 V-0 grade , ukuvimbela ama-circuits amafushane kanye nokusabalala kwe-thermal runaway.

Izintambo zangaphakathi kanye nokuvikelwa kwengxenye  Igoqa izintambo ezinama-voltage aphezulu kanye nezixhumi ukuze inikeze ukufakwa kwezinga lokushisa okuphezulu nokuvala, ukugwema amasekhethi amafushane okubangelwa ukugqwala kwe-electrolyte.

I-Thermal Management System Auxiliary Material  Inebanga elibanzi lokumelana nezinga lokushisa elingu --196℃~300℃  kanye ne-thermal conductivity elawulekayo, isetshenziswa njengento eyisisekelo yama-gaskets okufaka ukushisa kanye namashidi e-thermal conductive ukulinganisa izinga lokushisa langaphakathi lamaphakethe ebhethri.

Sekukonke Ukuvala Kwephakethe Lebhethri  Kusetshenziswa ekuvaleni kwezindlu kwephakethe lebhethri, imelana nokungena komswakamo wangaphandle kanye nokugqwala okuvela ekuvuzeni okuncane kwangaphakathi kwe-electrolyte.

Isidingo Esikhethekile 1: Ukumelana Okuhle Kakhulu Ezingxenyeni Ezihlukahlukene Ze-Electrolyte

I-electrolyte yebhethri ye-lithium igqwala kakhulu, ngakho ukumelana kwamakhemikhali kuyinkomba yokusebenza ebalulekile yendwangu ye-PTFE enezinga eliphezulu lokushisa:

I-Organic Solvents  Izingxenye eziyinhloko ze-electrolyte njenge-Ethylene Carbonate (EC) ne-Dimethyl Carbonate (DMC) yizincibilikisi eziqinile ze-polar. Amapulasitiki avamile azokhukhumala noma ancibilike lapho eveziwe, kuyilapho i-PTFE ihlala ingathinteki ngokuphelele.

I-Corrosive Electrolytes  I-Lithium Hexafluorophosphate (LiPF₆), usawoti owumgogodla we-electrolyte, izwela umswakama nokushisa futhi ibola kalula ikhiqize i-Hydrofluoric Acid (HF). I-HF igqwala kakhulu futhi ingaguguleka ingilazi nezinsimbi eziningi. Indwangu ye-PTFE enezinga eliphezulu lokushisa iletha ukumelana okuvelele ku-hydrofluoric acid futhi igcina ukusebenza okuzinzile ezindaweni ezinokhahlo.

Ukuzinza Kwe-Electrochemical  Ngaphansi kwezimo zokusebenza kwamandla kagesi aphezulu kanye nokushajwa kokushajwa ngaphakathi kwamabhethri, i-PTFE ifaka izici zamakhemikhali ezizinzile, ingakhiqizi ukusabela okuseceleni nge-electrolyte futhi akukho ukubola kwe-electrolyte okuyi-catalytic.

I-Salt Spray Corrosion Resistance Resistance  Electrolyte ukuvuza kwakha isifutho sikasawoti esigqwala kakhulu, lapho indwangu ye-PTFE enezinga lokushisa eliphezulu ikhombisa ukubekezelelana okuhle kakhulu.

Isidingo Esikhethekile 2: Ukuhlangabezana Nezimo Zokusebenza Zebhethri Eziqinile

Izinto ezibonakalayo eziphezulu ziyisisekelo; ukuzinza kwesikhathi eside ezindaweni zangempela zebhethri kufanele kuphumelele uhlolo oluqinile lokusebenza:

I-Electrolyte Immersion Aging Test  Lena yindlela yokuqinisekisa eqondile nebucayi kakhulu. Amasampula acwiliswa ku-electrolyte elungisiwe futhi agcinwa izinsuku noma amasonto endaweni yokushisa yegumbi noma amazinga okushisa aphakeme afana no-60℃ kanye no-85℃. Imikhiqizo efanelekile ayikhombisi ukubhamuza, ukubola noma ukuncibilika ngokuncipha kwesisindo esiphansi kakhulu.

Kafushane, indwangu ye-PTFE enezinga eliphezulu lokushisa isebenza njengesembozo esivikelayo, isithiyo sokuzihlukanisa kanye nokudlulisa okuphakathi kulo lonke ukukhiqizwa kwebhethri ye-lithium. Kungakhathaliseki ukuthi ibekezelela ukugqwala okukhulu kwe-electrolyte ngaphakathi kwamaseli noma ukunikeza ukuvikeleka okuzinzile ezinqubweni zokushisa okuphezulu ezifana nokucindezela okushisayo nokushisela, ukusebenza kwayo okuthembekile kubalulekile ukuze kuqinisekiswe isivuno sokukhiqiza, ukuphepha kokusebenza kanye nempilo yomjikelezo omude wamabhethri e-lithium.
