Iyini i-copper foil?
Icwecwe lethusi lisho umucu wethusi omncane kakhulu noma ishidi elinogqinsi olungaphansi kuka-200μm olucutshungulwa yi-electrolysis kanye ne-calendering, esetshenziswa kakhuluizifunda electronic, lithium-iyoniamabhethrinezinye izinkambu ezihlobene.
Ucwecwe lwethusi lungahlukaniswa lube izinhlobo ezimbili ngokuya ngenqubo yokukhiqiza ehlukene: ucwecwe lwethusi lwe-electrolytic kanye nocwecwe lwethusi olugoqiwe.
Ucwecwe lwethusi lwe-Electrolytic lusho ucwecwe lwethusi lwensimbi olukhiqizwa i-electrolysis enempahla yethusi njengento eluhlaza eyinhloko.
Ucwecwe lwethusi olugoqiwe lubhekisela emkhiqizweni owenziwe ngokugingqika ngokuphindaphindiwe futhi uhlanganiswe emgqeni wethusi onemba kakhulu ngomgomo wokucubungula ipulasitiki.
Ngokwezinkambu ezihlukene zohlelo lokusebenza, ingahlukaniswa ibe yi-foil yethusi yebhethri ye-lithium-ion kanye ne-foil yethusi evamile.
I-copper foil yebhethri ye-lithium-ion isetshenziswa ngokuyinhloko njengomqoqi wamanje we-anode webhethri ye-lithium-ion, futhi iyingxenye ebalulekile yesakhiwo se-electrode.
Ucwecwe lwethusi olujwayelekile luwungqimba oluncane lwe-foil yethusi olufakwe ungqimba olungezansi lwebhodi lesifunda, okungenye yezinto ezibalulekile eziyisisekelo ze-copper clad laminate (CCL) kanye nebhodi lesifunda eliphrintiwe (PCB), futhi lidlala indima yomqhubi.
I-copper foil yebhethri ye-lithium-ion isebenza njengesithwali se-anode material, kanye nomqoqi kanye nomqhubi we-anode electron yebhethri ye-lithium. Ngenxa ye-conductivity enhle, ukuthungwa okuthambile, ubuchwepheshe bokukhiqiza obuvuthiwe, kanye nenani eliphansi uma kuqhathaniswa, isiphenduke into ethandwayo yomqoqi wamanje we-anode wamabhethri e-lithium-ion.
Kodwa-ke, njengomqoqi wamanje we-anode wendabuko webhethri ye-lithium-ion, i-copper foil inezinkinga ezithile okunzima ukuzixazulula, okuhlanganisa izindleko eziphezulu zokukhiqiza kanye nezingozi zokuphepha ezibangelwa izinto zokusetshenziswa.
Ngakho-ke, indlela yamanje yokuthuthukiswa kwe-foil yethusi yendabuko icacile - ukuze ibe mncane futhi ikhanyise eyodwa ngobuningi obukhulu. Uma i-foil yethusi inogqinsi oluzacile, izoba nesisindo esincane seyunithi ngayinye yendawo, ukumelana nokuncane, kanye nokuminyana kwamandla ebhethri aphezulu.
Njengoba ukushuba kwefoyili yethusi esetshenziselwa ibhethri ye-lithium-ion kuba mncane, amandla okuqina kanye nokumelana nokuwohloka kokucindezela kuncipha. Ngamanye amazwi, i-foil yethusi ithambekele kakhulu ekuqhekekeni noma ekuqhekekeni, okungase kuthinte ukuphepha kwebhethri ye-lithium-ion. Ngaphandle kwalokho, lezo zici ezihlanganisa ukufana kogqinsi, amandla aqinile, kanye nokumanzisa kwendawo kunomthelela oqondile kumthamo, izinga lokukhiqiza, ukumelana, nempilo yesevisi yefoyili yethusi. Ngakho-ke, ukulinganiswa kokuqina kwe-foil yethusi kuyinqubo ebalulekile yokukhiqizwa kwe-foil yethusi.
Ngokusho kobukhulu be-foil yethusi, ingahlukaniswa ibe:
I-foil yethusi ezacile (≤6μm)
I-foil yethusi ezacile kakhulu (6-12μm)
I-foil yethusi ezacile (12-18μm)
I-foil yethusi evamile (18-70μm)
I-foil yethusi ewugqinsi (> 70μm)
Ubukhulu be-X-ray ku-inthanethi (okwangempeladensity) ukulinganisagauge forucwecwe lwethusieyakhiwe i-Dacheng Precision ingasetshenziswa ekuhlolweni kokuqina kwe-foil yethusi enjinini ye-foil engcolile kanye nenqubo yokusika. Ukunemba kwayo okuphezulu kungasiza ukunqoba izinkinga zokukhiqiza ze-foil yethusi esebenza kahle kakhulu.
Izinzuzo zokuqina kwe-X-ray ku-inthanethi (okwangempeladensity) ukulinganisagauge forucwecwe lwethusi
- Uhlaka lokuskena lungenziwa ngokwezifiso ngokuya ngosayizi wenkundla.
- Ingakwazi ukuthola ukutholakala ku-inthanethi kokuminyana kwe-areal ye-copper foil, futhi inomsebenzi wempendulo yedatha yesikhathi sangempela ukuze kuzuzwe umphumela ozenzakalelayo we-loop evaliwe. Ingacindezela kakhulu ukuguquguquka kokuminyana kwendawo, futhi ilawule ukuguquguquka kwebanga elingu-+0.3um.
- Uhlelo lokuzilinganisa luqeda zonke izinhlobo zezici zokuphazamiseka ukuze kuqinisekiswe ukusebenza okuzinzile nokunembile kwesistimu yokulinganisa.
Isistimu ye-loop evaliwe yogqinsi lwe-X-ray ku-line (ukuminyana kwe-areal) igeji yokulinganisa yefoyili yethusi ingafinyelela ukutholwa kwesikhathi sangempela kogqinsi noma idatha yokuminyana kwe-real, elawula ukuvulwa kwamavalvu. Isistimu yokulinganisa ingabala ngesikhathi esisodwa ukuchezuka kwendawo ngayinye yokulinganisa, ilawule i-valve yokugeleza ngokuvumelana nesimiso sokulawula se-PID, ukuze ilawule ukushuba noma ukuminyana kwendawo.
Singenza imishini egcizelele ngokwezidingo zakho zobuchwepheshe. Noma yimiphi imibuzo siyajabula ukuyiphendula, pls thumela imibuzo yakho nama-oda.
