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 izi-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 okwandayo 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 okuqhuba ukushisa ukuze kulinganiswe izinga lokushisa langaphakathi lamaphakethe ebhethri.

Sekukonke Ukuvala Kwephakethe Lebhethri  Kusetshenziswa ekuvaleni kwezindlu zephakethe 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 ezifana ne-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 zamandla kagesi aphezulu kanye nokushajwa kokushajwa ngaphakathi kwamabhethri, i-PTFE ifaka izici zamakhemikhali ezizinzile, ingakhiqizi ukusabela okuseceleni kwe-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 ukubekezelela 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 indlela yokuqinisekisa eqondile nebucayi kakhulu. Amasampuli 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.
