Ukukhetha Umshini Ofanele Wokumboza Wokukhiqiza Amabhethri e-Lithium-Ion
Isingeniso
Ekukhiqizweni kwamabhethri e-lithium-ion, ikhwalithi ye-electrode inquma ngqo ukusebenza kwebhethri kanye nokusebenza kahle kokukhiqiza. Kodwa-ke, abakhiqizi bavame ukubhekana nezinselele ezifana nokungahambisani kokugqoka, ukusebenza kahle okuphansi, kanye namazinga aphezulu okukhubazeka.
Ukuze kuxazululwe lezi zinkinga, imishini yokumboza isibe yimishini ebalulekile emigqeni yokukhiqiza amabhethri yesimanje.
Uyini Umshini Wokumboza?
Umshini wokumboza usetshenziselwa ukufaka udaka ku-aluminium noma ku-copper foil ukuze kwakhiwe ama-electrode ebhethri. Usetshenziswa kabanzi ku:
- Amabhethri kagesi e-EV
- Izinhlelo zokugcina amandla (ESS)
- Amabhethri e-lithium-ion asetshenziswa ngabathengi
Kungenye yezinyathelo ezibaluleke kakhulu ekukhiqizweni kwama-electrode.
Kungani Ukugqoka Kubaluleke Kangaka? (Amaphuzu Obuhlungu Embonini)
- Ukumbozwa okungalingani kuholela ekusebenzeni kwebhethri okungalingani
- Amaphutha anjengama-bubbles kanye nemifantu anciphisa isivuno
- Imigqa yokumboza yendabuko ivame ukusebenza ku-80–100 m/min, okunciphisa ukusebenza kahle kokukhiqiza ngezinga elikhulu
- Imfucuza yezinto ezibonakalayo inyusa izindleko zokukhiqiza
Izixazululo Ezivamile Zokumboza
1. Ukwembozwa kwe-Extrusion (Slot Die)
- Ukunemba okuphezulu
- Ifanele ukukhiqizwa okusheshayo
2. Ukugqoka nge-Gravure
- Isetshenziselwa ukugqoka i-primer
- Kuqiza kahle
3. Isimbozo Sokuhlukanisa
- Kuthuthukisa ukusebenza kokuphepha
Kungani Ukugqoka Okunezinhlangothi Ezimbili Kuqala Ukuba Okujwayelekile
Uma kuqhathaniswa nokugqoka ohlangothini olulodwa, ukugqoka ohlangothini olulodwa kunikeza:
- Ukuthuthukiswa kokusebenza kahle kokukhiqiza cishe ngo-60-80% ezindaweni zokukhiqiza eziqhubekayo
- Ukuzinza okungcono
- Izindleko eziphansi
Kubaluleke kakhulu ekukhiqizweni kwebhethri elikhulu.
Isixazululo Esinconywayo: I-Double-Layer High-Speed Extrusion Coater
Ukuze kuhlangatshezwane nalezi zidingo, abakhiqizi abaphambili basebenzisa imishini yokumboza i-extrusion enezingqimba ezimbili ngesivinini esikhulu.
Ukuze kukhiqizwe amabhethri asheshayo namakhulu, abakhiqizi bavame ukusebenzisa izinhlelo zokumboza ezihlanganisiwe ezakhiwe abahlinzeki abanjengoPengjin, ikakhulukazi kumaphrojekthi asezingeni le-gigafactory adinga kokubili ukunemba kanye nokusetshenziswa.
Izici Eziyinhloko:
- Sheshisa kuze kufike ku- 160 m/min, okuvumela ukudluliswa okuphezulu
- Ubuningi obuphindwe kabili ≤ ±1.0%
- Ukulawula ukucindezeleka ≤ ±2N
- Ukuqondanisa ≤ ±0.5 mm
Ekuthuthukisweni okusebenzayo, abanye abakhiqizi bamabhethri babike ukuthuthuka kokusebenza kahle okungaphezu kuka-30% ngemuva kokushintsha kusuka ezinhlelweni zokumboza ezivamile kuya kwizixazululo zokukhipha ezingqimba ezimbili, kanye nokuncipha kwemfucuza yezinto ezibonakalayo.
Izimo Zohlelo Lokusebenza
- Izimboni ezinkulu zamabhethri e-EV
- Imigqa yokukhiqiza isitoreji samandla
- Ukukhiqizwa kwamabhethri kwabathengi
- Imigqa yokushayela ye-R&D
Isiphetho
Ekukhiqizweni kwamabhethri e-lithium, imishini yokumboza ayiyona nje imishini ebalulekile kodwa futhi iyisici esibalulekile ekunqumeni ukuncintisana kokukhiqiza.
Njengoba isidingo sokusebenza kahle kanye nokungaguquguquki sikhula, izixazululo zokumboza ezinezinhlangothi ezimbili ezisheshayo ziya ngokuya zamukelwa ngabakhiqizi abaphambili.
Uma usebenza kuphrojekthi entsha yebhethri noma ulungisa umugqa wokukhiqiza okhona, ukuqonda ikhambi elifanele lokumboza kungenza umehluko omkhulu. Ukuhlola ubuchwepheshe obutholakalayo nokubonisana nabahlinzeki bemishini abanolwazi kungakusiza ukuthi wenze isinqumo esinolwazi oluthe xaxa.
