Ukwenziwa kwezinto ezinhle nezingezinhle

Ekulungiseni izinto ze-electrode ezingaphili zamabhethri e-lithium ion, ukusabela kwesimo esiqinile sokushisa okuphezulu yikona okuvame ukusetshenziswa kakhulu.Izinga lokushisa eliphezulu eliqinile lesigaba sokusabela: libhekisela enqubweni lapho izinto ezisabelayo ezihlanganisa izinto zesigaba esiqinile zisabela isikhathi esithile ezingeni lokushisa elithile futhi zikhiqize ukusabela kwamakhemikhali ngokuhlukana phakathi kwezakhi ezihlukahlukene ukuze kukhiqizwe izinhlanganisela eziqine kakhulu ezingeni lokushisa elithile. , okuhlanganisa ukusabela okuqinile-okuqinile, ukusabela kwegesi eqinile kanye nokusabela koketshezi oluqinile.

Ngisho noma indlela ye-sol-gel, indlela ye-coprecipitation, indlela ye-hydrothermal kanye nendlela ye-solvothermal isetshenziswa, ukusabela kwesigaba esiqinile noma i-solid-phase sintering ekushiseni okuphezulu kuyadingeka.Lokhu kungenxa yokuthi isimiso sokusebenza sebhethri ye-lithium-ion sidinga ukuthi impahla yayo ye-electrode ingafaka ngokuphindaphindiwe futhi isuse i-li +, ngakho-ke isakhiwo sayo se-lattice kufanele sibe nokuzinza okwanele, okudinga ukuthi i-crystallinity yezinto ezisebenzayo kufanele ibe phezulu futhi isakhiwo se-crystal kufanele sibe njalo. .Lokhu kunzima ukufeza ngaphansi kwezimo zokushisa eziphansi, ngakho-ke izinto ze-electrode zamabhethri e-lithium-ion asetshenziswa ngempela manje ngokuyisisekelo zitholakala ngokusabela kwe-high-temperature solid-state reaction.

I-cathode material processing processing line ikakhulukazi ihlanganisa uhlelo lokuxuba, uhlelo lwe-sintering, uhlelo lokuchoboza, uhlelo lokugeza amanzi (i-nickel ephezulu kuphela), uhlelo lokupakisha, uhlelo lokudlulisa impushana kanye nesistimu yokulawula ehlakaniphile.

Lapho inqubo yokuxuba emanzi isetshenziswa ekukhiqizeni izinto ze-cathode zamabhethri e-lithium-ion, izinkinga zokomisa zivame ukuhlangana nazo.Ama-solvents ahlukene asetshenziswa ekuxubeni okumanzi azoholela ezinkambisweni ezahlukene zokumisa kanye nemishini.Njengamanje, kunezinhlobo ezimbili eziyinhloko zezincibilikisi ezisetshenziswa ekuxubeni okumanzi: izincibilikisi ezingenawo amanzi, okuyizincibilikisi eziphilayo ezifana ne-ethanol, i-acetone, njll;I-solvent yamanzi.Imishini yokomisa yokuxuba okumanzi kwe-lithium-ion battery cathode materials ikakhulukazi ihlanganisa: vacuum rotary dryer, vacuum rake dryer, spray dryer, vacuum belt dryer.

Ukukhiqizwa kwezimboni zezinto ze-cathode zamabhethri e-lithium-ion ngokuvamile kusebenzisa inqubo ye-solid-state synthesis synthesis yezinga eliphezulu lokushisa, futhi umnyombo wayo kanye nemishini eyinhloko i-sintering kiln.Izinto zokusetshenziswa zokukhiqiza izinto ze-lithium-ion battery cathode zixutshwe ngokulinganayo futhi zomiswe, bese zilayishwa kuhhavini ukuze zifakwe emanzini, bese zithululwa kuhhavini zibe yinqubo yokuchotshozwa nokuhlukanisa.Ukuze kukhiqizwe izinto ze-cathode, izinkomba zobuchwepheshe nezomnotho ezifana nezinga lokushisa lokulawula izinga lokushisa, ukufana kwezinga lokushisa, ukulawulwa komkhathi nokufana, ukuqhubeka, amandla okukhiqiza, ukusetshenziswa kwamandla kanye ne-automation degree ye-ovini kubaluleke kakhulu.Njengamanje, imishini eyinhloko yokushisa esetshenziswa ekukhiqizeni izinto ze-cathode yi-pusher kiln, i-roller kiln kanye nesithando somlilo sensimbi.

◼ I-roller kiln iwuhubhe losayizi ophakathi nendawo enokufudumeza okuqhubekayo nokucwilisa.

◼ Ngokomkhathi wesithando somlilo, njenge-pusher kiln, i-roller kiln nayo ihlukaniswe yaba i-air kiln kanye ne-atmosphere.

• I-Air Kiln: ikakhulukazi esetshenziselwa izinto zokushisa ezidinga umoya we-oxidizing, njengezinto ze-lithium manganate, izinto ze-lithium cobalt oxide, izinto ze-ternary, njll;
• I-Atmosphere Kiln: ikakhulukazi esetshenziselwa izinto ze-NCA ternary, izinto ze-lithium iron phosphate (LFP), izinto ze-graphite anode nezinye izinto ezishisayo ezidinga umoya (njenge-N2 noma i-O2) ukuvikelwa kwegesi.

◼ I-roller kiln ithatha inqubo yokugingqa, ngakho ubude behhashi ngeke buthintwa amandla ashukumisayo.Ngokwethiyori, kungaba okungenamkhawulo.Izici zesakhiwo somgodi wesithando somlilo, ukungaguquguquki okungcono lapho kuqhunyiswa imikhiqizo, kanye nesakhiwo esikhulu sembobo yomlilo kulungele ukuhamba komoya esithandweni kanye nokukhipha amanzi kanye nokukhishwa kwenjoloba kwemikhiqizo.Ithuluzi elincanyelwayo lokuthatha indawo ye-pusher kiln ukuze uthole ukukhiqizwa okuphezulu ngempela.

◼ Njengamanje, i-lithium cobalt oxide, i-ternary, i-lithium manganate nezinye izinto ze-cathode zamabhethri e-lithium-ion zishiswa kuhhavini ye-roller emoyeni, kuyilapho i-lithium iron phosphate ifakwa kuhhavini ye-roller evikelwe i-nitrogen, futhi i-NCA ifakwe ku-roller. iziko elivikelwe umoya-mpilo.
