Yintoni ifoyile yobhedu?
Ifoyile yobhedu ibhekiselele kumcu wobhedu obhityileyo kakhulu okanye ishiti elinobunzima obungaphantsi kwe-200μm ecutshungulwa yi-electrolysis kunye ne-calendering, esetyenziswa kakhuluiisekethe zombane, lithium-ioniibhetrikunye neminye imimandla enxulumeneyo.
Ifoyile yobhedu inokwahlulwa ibe ziindidi ezimbini ngokwenkqubo yokuvelisa eyahlukileyo: ifoyile yobhedu ye-electrolytic kunye nefoyile yobhedu eqengqelekayo.
Ifoyile yobhedu ye-Electrolytic ibhekisa kwifoyile yobhedu yesinyithi eveliswa yi-electrolysis ngezinto zobhedu njengeyona nto iphambili ekrwada.
Ifoyile yobhedu eqengqelekisiweyo ibhekisa kwimveliso eyenziwe ngokuqengqeleka ngokuphindaphindiweyo kunye nokuqhotyoshelwa kumcu wobhedu ochanekileyo ngomgaqo wokusetyenzwa kweplastiki.
Ngokwamacandelo ahlukeneyo esicelo, inokwahlulwa ibe yifoyile yobhedu yebhetri ye-lithium-ion kunye ne-foil yobhedu eqhelekileyo.
I-copper foil ye-lithium-ion ibhetri isetyenziswa kakhulu njenge-anode umqokeleli wangoku webhetri ye-lithium-ion, kwaye iyinxalenye ebalulekileyo yesakhiwo se-electrode.
Ifoyile yobhedu esemgangathweni ngumaleko obhityileyo wefoyile yobhedu ebekwe kumaleko asezantsi ebhodi yesekethe, yenye yezinto ezibalulekileyo ezisisiseko selaminate yobhedu (CCL) kunye nebhodi yesekethe eprintiweyo (PCB), kwaye idlala indima yomqhubi.
I-copper foil ye-lithium-ion ibhetri isebenza njengomphathi wezinto ze-anode, kunye nomqokeleli kunye nomqhubi we-anode electron ye-lithium ibhetri. Ngenxa ye-conductivity entle, ukuthungwa okuthambileyo, itekhnoloji yokuvelisa eqolileyo, kunye nexabiso eliphantsi ngokwentelekiso, iye yaba yinto ekhethwayo kumqokeleli wangoku we-anode yeebhetri ze-lithium-ion.
Nangona kunjalo, njengomqokeleli we-anode yangoku yebhetri ye-lithium-ion, i-foil yobhedu ineengxaki ezithile ezinzima ukuzicombulula, kubandakanywa iindleko eziphezulu zokuvelisa kunye neengozi zokhuseleko ezibangelwa yizinto eziluhlaza.
Ngoko ke, indlela yokuphuhlisa yangoku ye-foil yobhedu yendabuko icacile - ukuba ibe yincinci kwaye ilula enye enobuninzi obuphezulu. Ukuba ifoyile yobhedu inobungqingqwa obuncinci, iya kuba nobunzima obulula beyunithi yendawo nganye, ukuchasana okuncinci, kunye noxinzelelo lwamandla ebhetri aphezulu.
Njengoko ubukhulu befoyile yobhedu esetyenziselwa ibhetri ye-lithium-ion buba buthathaka, amandla okuqina kunye nokumelana ne-deformation yoxinzelelo kuncipha. Ngamanye amazwi, i-foil yobhedu iyancipha ngakumbi ukuphuka okanye ukuqhekeka, okunokuchaphazela ukhuseleko lwebhetri ye-lithium-ion. Ngaphandle koko, ezo zinto zibandakanya ukufana kobukhulu, amandla okuqina, kunye nokumanzisa komphezulu kunefuthe elithe ngqo kumthamo, izinga lesivuno, ukuxhathisa, kunye nobomi benkonzo yefoyile yobhedu. Ngoko ke, ukulinganiswa kobunzima be-foil yobhedu yinkqubo ebalulekileyo yokuvelisa i-foil yobhedu.
Ngokobunzima befoyile yobhedu, inokwahlulwa ibe:
Ifoyile yobhedu ebhityileyo (≤6μm)
Ifoyile yobhedu ebhityileyo kakhulu (6-12μm)
Ifoyile yobhedu ebhityileyo (12-18μm)
Ifoyile yobhedu eqhelekileyo (18-70μm)
Ifoyile yobhedu engqindilili (> 70μm)
X-reyi kwi-intanethi ubukhulu (indawodensity) ukulinganisaigeyiji yeifoyile yobheduiphuhliswe yi-Dacheng Precision ingasetyenziswa kuhlolo olungqingqwa lwefoyile yobhedu kwi-injini yefoyile ekrwada kunye nenkqubo yokuqhawula. Ukuchaneka kwayo okuphezulu kunokunceda ukunqoba iingxaki zemveliso ye-high-performance ultra-thin copper foil.
Izinto ezilungileyo zeX-reyi kwi-intanethi ubukhulu (indawodensity) ukulinganisaigeyiji yeifoyile yobhedu
- Isakhelo sokuskena sinokwenziwa ngokwesayizi yentsimi.
- Iyakwazi ukufezekisa ukufunyanwa kwe-intanethi ye-foil ye-copper density yendawo, kwaye inomsebenzi wengxelo yedatha yexesha langempela ukufezekisa umphumo wokuvala i-loop. Inokucinezela kakhulu ukuguquguquka koxinzelelo lwendawo, kunye nokulawula ukuguquguquka koluhlu lwe +0.3um.
- Inkqubo yokulinganisa i-self-calibration isusa zonke iintlobo zokuphazamiseka ukuze kuqinisekiswe ukusebenza okuzinzileyo kunye nokuchanekileyo kwenkqubo yokulinganisa.
Inkqubo evaliweyo ye-X-reyi kwi-line ubukhulu (ubuninzi be-areal) igeyiji yokulinganisa i-foil yobhedu inokufezekisa ukufunyanwa kwexesha langempela lobuninzi okanye idatha yobuninzi bendawo, ukulawula ukuvulwa kwevalve. Inkqubo yokulinganisa inokubala ngexesha elifanayo ukuphambuka kwendawo nganye yokulinganisa, ukulawula i-valve yokuhamba ngokomgaqo wokulawula i-PID, ukuze ulawule ubuninzi okanye ubuninzi bendawo.
Sinokwenza izixhobo ezilungiselelwe ngokweemfuno zakho zobugcisa. Nayiphi na imibuzo siyavuya ukuyiphendula, pls thumela imibuzo yakho kunye nemiyalelo.
