Usetyenziso lwe-PTFE High-Temperature Fabric in Lithium Battery Industry

Njengomvelisi we-PTFE welaphu lobushushu obuphezulu, I-Jiangsu Aokai New Materials ikunika intshayelelo yobungcali. Kwimveliso yebhetri ye-lithium, ilaphu le-PTFE elinobushushu obuphezulu lisetyenziselwa ukukhusela, ukuhlukaniswa kunye nokuhanjiswa kwiinkqubo eziphambili ngenxa yokumelana nokushisa okuphezulu, ukungabi namachiza kunye nepropati engaguqukiyo. Ukuxhathisa kwayo kwi-electrolyte corrosion ibandakanya iimfuno ezingqongqo kakhulu zefektri kunokumelana nokukhula okulula.

ISicelo esingundoqo 1: Ukuveliswa kwe-Electrode kunye neNdibano yeeSeli

Ekwenziweni kwee-electrode zebhetri kunye neenkqubo zokuhlanganisa iiseli, ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa kakhulu ukuhambisa, ukukhuselwa kunye nokucinezelwa okushushu bodwa.

I-Electrode Drying Conveyor Belt  Isebenza njengebhanti yokuhambisa ngexesha lokumisa ubushushu obuphezulu be-electrode elungileyo kunye ne-negative kwi-120 ℃ ~ 180 ℃. Amandla ayo aphantsi komhlaba athintela ukunamathela kwezinto ze-ternary, igraphite kunye nezinye i-slurries, ukuphepha ukungcoliswa kunye nomonakalo kwiingubo ze-electrode.

Ukutywinwa kwe-Cell Hot Press  Ngobunzima obuqhelekileyo be-0.18 mm, busebenza njengento yodwa kunye nokhuseleko phakathi kwentloko ecinezelayo eshushu kunye ne-pouch cell ngexesha lokutywinwa kwe-thermal. Ukumelana namaqondo obushushu angaphezu kwe-240 ℃, iqinisekisa ukuhanjiswa kobushushu obufanayo, inqanda ukuncamathela kwaye iphucula isivuno sokupakisha.

I-Tab Welding kunye noKhuseleko lwe-Hot Press  Isetyenziswa njengento yokukhusela kunye neyodwa ngexesha le-tab ye-welding kunye noxinzelelo olushushu malunga ne-200℃. Ebonisa ukugquma okuphezulu kunye ne-dielectric constant engaphantsi kwe-2.6, ikhusela ngokufanelekileyo iisekethe ezimfutshane, ixhathisa umphunga we-electrolyte, kwaye ikhusela ukuchasana okwandisiweyo okubangelwa ukubola kunye ne-oxidation yeethebhu zethusi / i-aluminium.

ISicelo esingundoqo se-2: INdibano yePakethi yeBattery kunye nokuKhuselwa kweNkqubo

Kwindibano yokupakisha ibhetri, igxile kukhuseleko lombane kunye nolawulo lwe-thermal.

I-Insulation Isolation phakathi kweeSeli  ezibekwe phakathi kweeseli zomntu ngamnye, zibonelela ngokugqwesileyo kunye nokutshatyalaliswa komlilo ukuya kwi- UL94 V-0 ibakala , ukuthintela iisekethe ezimfutshane kunye nokusasazeka kwe-thermal runaway.

I-Internal Wiring kunye noKhuseleko lweCandelo  Igubungela i-wiring ye-voltage ephezulu kunye nezixhumi ukubonelela ngobushushu obuphezulu kunye nokutywinwa, ukuphepha iisekethe ezimfutshane ezibangelwa yi-electrolyte corrosion.

I-Thermal Management System eNcedisayo yeMathiriyeli  Ngoluhlu olubanzi lokumelana nobushushu be -196 ℃ ~ 300 ℃  kunye nokulawulwa kwe-thermal conductivity, isetyenziselwa njengesiseko sezinto ezisisiseko se-gaskets yokugquma ubushushu kunye namaphepha okuqhuba i-thermal ukulinganisa ubushushu bangaphakathi beepakethi zebhetri.

Ukutywinwa kwePakethi yeBattery xa iyonke  iFakelwe kwibhetri yepakethe yokutywinwa kwezindlu, iyaxhathisa ukungena kokufuma kwangaphandle kunye nokubola kokuvuza okuncinci kwe-electrolyte yangaphakathi.

Imfuno ekhethekileyo ye-1: Ukuchasana okugqwesileyo kwiintlobo ezahlukeneyo ze-Electrolyte

I-electrolyte yebhetri yeLithium iyonakalise kakhulu, ke ngoko ukumelana neekhemikhali luphawu olubalulekileyo lokusebenza kwelaphu lobushushu obuphezulu be-PTFE:

Izinyibilikisi ze-Organic  Amalungu angundoqo e-electrolyte afana ne-Ethylene Carbonate (EC) kunye ne-Dimethyl Carbonate (DMC) zizinyibilikisi ezomeleleyo ze-polar. Iiplastiki eziqhelekileyo ziya kudumba okanye zinyibilike xa ziveziwe, ngelixa i-PTFE ihlala ingachaphazeleki ngokupheleleyo.

I-Corrosive Electrolytes  I-Lithium Hexafluorophosphate (LiPF₆), eyona tyuwa ingundoqo ye-electrolyte, inovelwano kukufuma nobushushu kwaye ibola lula ukuvelisa i-Hydrofluoric Acid (HF). I-HF iyonakalise kakhulu kwaye inokukhukulisa iglasi kunye neentsimbi ezininzi. Ilaphu le-PTFE elinobushushu obuphezulu linikezela ukuxhathisa okubalaseleyo kwi-hydrofluoric acid kwaye ligcina ukusebenza okuzinzileyo kwiindawo ezinoburharha.

Ukuzinza kwe-Electrochemical  Ngaphantsi kombane ophezulu kunye neemeko zokusebenza zokukhutshwa kwentlawulo ngaphakathi kweebhetri, i-PTFE ibonisa iipropati zekhemikhali ezizinzile, ukuvelisa akukho zimpendulo zecala kunye ne-electrolyte kwaye akukho ukubola kwe-catalytic ye-electrolyte.

Isitshizi seTyuwa ukuNxwala kokuNgxwala  kwe-Electrolyte ukuvuza kwenza isitshizi setyuwa esonakalisayo, apho ilaphu le-PTFE elinobushushu obuphezulu libonisa unyamezelo olugqwesileyo.

IMfuneko eKhethekileyo yesi-2: Ukuhlangabezana neeMeko zokuSebenza kweBhetri ezingqongqo

Iipropati zezinto eziphezulu zisisiseko; Uzinzo lwexesha elide kwindawo yebhetri yokwenyani kufuneka luphumelele iimvavanyo ezinzima zokusebenza:

Uvavanyo lokuguga lwe-Electrolyte  Le yeyona ndlela ichanekileyo kwaye ibaluleke kakhulu yokuqinisekisa. Iisampulu zintywiliselwa kwi-electrolyte eyenziweyo kwaye igcinwe iintsuku okanye iiveki kwiqondo lobushushu begumbi okanye amaqondo obushushu aphezulu anje nge60℃ kunye ne85℃. Iimveliso ezifanelekileyo azibonisi ukudumba, ukudilika okanye ukunyibilika ngokuncipha okuphantsi kobunzima.

Isishwankathelo, ilaphu lobushushu obuphezulu be-PTFE lisebenza njengesigqubuthelo esikhuselayo, isithintelo sokwahlula kunye nokuhambisa okuphakathi kulo lonke ukwenziwa kwebhetri ye-lithium. Ingaba ukunyamezela ukubola kwe-electrolyte enzima ngaphakathi kweeseli okanye ukubonelela ngokhuseleko oluzinzileyo kwiinkqubo eziphezulu zokushisa ezifana nokucofa okutshisa kunye ne-welding, ukusebenza kwayo okuthembekileyo kubalulekile ukuqinisekisa isivuno semveliso, ukhuseleko lokusebenza kunye nobomi bomjikelezo omude weebhetri ze-lithium.
