Isingeniso:
Amabhethri e-lithiumuhlobo lwebhethri olusebenzisa insimbi ye-lithium noma i-lithium alloy njengento engeyona i-electrode futhi lusebenzisa isisombululo se-electrolyte esingemanzi. Ngenxa yezakhiwo zamakhemikhali ezisebenzayo kakhulu zensimbi ye-lithium, ukucubungula, ukugcina, kanye nokusetshenziswa kwensimbi ye-lithium kunezidingo eziphezulu kakhulu zemvelo. Okulandelayo, ake sibheke izinqubo ze-homogenization, coating, kanye ne-rolling ekulungiseleleni amabhethri e-lithium.
Ukuhlanganiswa kwe-electrode okuhle nokubi
I-electrode yebhethri le-lithium-ion iyisici esibaluleke kakhulu seseli yebhethri. I-homogenization ye-electrode enhle nembi ibhekisela enkambisweni yokulungiselela i-slurry eboshwe kumashidi e-electrode amahle nembi e-lithium ion. Ukulungiswa kwe-slurry kudinga ukuxuba izinto ze-electrode ezinhle, izinto ze-electrode ezimbi, i-ejenti eqhubayo kanye ne-binder. I-slurry elungiselelwe idinga ukufana futhi izinzile.
Abakhiqizi abahlukene bebhethri le-lithium banezindlela zabo zenqubo yokwenza i-homogenization. Ukuhleleka kokufaka izinto, isilinganiso sokufaka izinto kanye nenqubo yokuxuba enkambisweni yokwenza i-homogenization kunethonya elikhulu emphumeleni wokwenza i-homogenization. Ngemva kokwenza i-homogenization, i-slurry idinga ukuhlolwa okuqukethwe okuqinile, i-viscosity, ubuncane, njll. ukuqinisekisa ukuthi ukusebenza kwe-slurry kuyahlangabezana nezidingo.
Ukugqoka
Inqubo yokumboza inqubo esekelwe ekufundweni kwezakhiwo zoketshezi, lapho ungqimba olulodwa noma ngaphezulu loketshezi lumbozwa khona ku-substrate. I-substrate ivame ukuba ifilimu eguquguqukayo noma iphepha elisekelayo, bese ungqimba loketshezi olumboziwe lomiswa kuhhavini noma luhlanzwe ukuze kwakhiwe ungqimba lwefilimu olunemisebenzi ekhethekile.
Ukumboza kuyinqubo ebalulekile ekulungiseleleni amaseli ebhethri. Ikhwalithi yokumboza ihlobene ngqo nekhwalithi yebhethri. Ngesikhathi esifanayo, amabhethri e-lithium-ion azwela kakhulu kumswakama ngenxa yezici zesistimu. Inani elincane lomswakama lingaba nomthelela omkhulu ekusebenzeni kukagesi kwebhethri; izinga lokusebenza kokumboza lihlobene ngqo nezinkomba ezisebenzayo njengezindleko kanye nesilinganiso esifanelekile.
Inqubo yokukhiqiza ukumboza
I-substrate embozwe iyasuswa kudivayisi yokukhulula bese ifakwa emshinini wokumboza. Ngemva kokuba ikhanda nomsila we-substrate kuxhunywe ukuze kwakheke ibhande eliqhubekayo etafuleni lokunamathisela, kufakwa kudivayisi yokulungisa ukucindezeleka kanye nedivayisi yokulungisa ukuphambuka okuzenzakalelayo yidivayisi yokudonsa, bese kungena kudivayisi yokumboza ngemva kokulungisa ukucindezeleka kwendlela yeshidi kanye nendawo yendlela yeshidi. I-slurry yesigxobo se-pole imbozwe ngezigaba kudivayisi yokumboza ngokuya ngenani lokumboza elinqunyiwe kanye nobude obungenalutho.
Uma kugqokwa izinhlangothi ezimbili, uqweqwe lwangaphambili kanye nobude obungenalutho kulandelelwa ngokuzenzakalelayo ukuze kugqokwe. I-electrode emanzi ngemva koqweqwe ithunyelwa esiteshini sokomisa ukuze yome. Izinga lokushisa lokomisa libekwa ngokwejubane loqweqwe kanye nobukhulu boqweqwe. I-electrode eyomile igoqwa ngemva kokulungiswa kokucindezeleka kanye nokulungiswa kokuphambuka okuzenzakalelayo kwesinyathelo esilandelayo sokucubungula.
Ukugingqa
Inqubo yokugoqa izingcezu ze-lithium battery pole inqubo yokukhiqiza ecindezela ngokulinganayo izinto zokusetshenziswa ezifana nezinto ezisebenzayo, ama-conductor agent kanye nama-binder ku-foil yensimbi. Ngenqubo yokugoqa, ingcezu ye-pole ingaba nendawo esebenzayo ye-electrochemical ephezulu, ngaleyo ndlela ithuthukise ubuningi bamandla kanye nokusebenza kokushaja nokukhipha kwebhethri. Ngesikhathi esifanayo, inqubo yokugoqa ingenza futhi ingcezu ye-pole ibe namandla aphezulu esakhiwo kanye nokuvumelana okuhle, okusiza ukuthuthukisa impilo yomjikelezo kanye nokuphepha kwebhethri.
Inqubo yokukhiqiza egoqekayo
Inqubo yokugoqa izingcezu ze-lithium battery pole ihlanganisa ikakhulukazi ukulungiswa kwezinto zokusetshenziswa, ukuxuba, ukuqinisa, ukubumba nezinye izixhumanisi.
Ukulungiswa kwezinto zokusetshenziswa kuhilela ukuxuba izinto zokusetshenziswa ezahlukene ngokulinganayo bese ufaka inani elifanele le-solvent ukuze uxube ukuze uthole i-slurry eqinile.
Isixhumanisi sokuxuba siwukuxuba izinto zokusetshenziswa ezahlukene ngokulinganayo ukuze kuhlanganiswe futhi kulungiswe okulandelayo.
Isixhumanisi sokuqiniswa siwukucindezela i-slurry ngokucindezela kwe-roller ukuze izinhlayiya zezinto ezisebenzayo zibekwe eduze ukuze zakhe ucezu lwe-pole olunamandla athile esakhiwo. Isixhumanisi sokubumba siwukwelapha ucezu lwe-pole ngokushisa okuphezulu kanye nokucindezela okuphezulu ngemishini efana nokucindezela okushisayo ukulungisa ukuma nobukhulu bengxenye ye-pole.
Isiphetho
Inqubo yokulungiselela amabhethri e-lithium iyinkimbinkimbi kakhulu, futhi isinyathelo ngasinye sibalulekile. Hlala uqaphile kubhulogi likaHeltec futhi sizoqhubeka nokukwazisa ngolwazi olufanele mayelana namabhethri e-lithium.
I-Heltec Energy ingumlingani wakho othembekile ekukhiqizeni amaphakethe ebhethri. Ngokugxila kwethu ocwaningweni nasekuthuthukisweni okungapheli, kanye nohlu lwethu oluphelele lwezesekeli zebhethri, sinikeza izixazululo ezifika kanye ukuze kuhlangatshezwane nezidingo ezishintshayo zomkhakha. Ukuzibophezela kwethu ekwenzeni kahle, izixazululo ezenzelwe wena, kanye nokubambisana okuqinile kwamakhasimende kusenza sibe yisinqumo esikhethwa kakhulu ngabakhiqizi nabahlinzeki bamaphakethe ebhethri emhlabeni jikelele.
