Okugoberera obutasalako amaanyi g’amaanyi aga waggulu, obulamu bw’enzirukanya empanvu, n’obukuumi obw’amaanyi mu lithium-okuteeka essira ku kuteeka essira eritali lya bulijjo ku mutindo n’obwesigwa bw’okukola ebyuma. Ensonga enkulu, naye etera okunyoomebwa, mu nkola eno kwe kukwatagana kw’ensengekera wakati w’ebintu ebikola ebyuma ebikola n’ebyuma byabwe ebikung’aanya amasannyalaze. Okunywerera okunafu kuleeta okusannyalala, okuziyiza okw’omunda okweyongera, n’okulemererwa okw’akatyabaga. Ekiwandiiko kino kinoonyereza ku ngeri tekinologiya ow’omulembe ow’okujjanjaba Corona gy’awa eky’okugonjoola ekinywevu, eky’okulinnyisa, n’eky’obutonde-ekikwatagana okutumbula ennyo okuwangaala kw’okusiiga bbaatule nga kilongoosa amaanyi ag’okungulu n’okutumbula enkolagana ey’oku ntikko.
Okusoomoozebwa kw’okunyweza mu kukola bbaatule .
Ku mutima gwa buli lithium-eyo battery egalamira electrode: a slurry of active materials, conductive additives, ne binders ezisiigiddwa ku thin metal fo metal foils (typically aluminum for the cathode and copper for the anode). Omulimu n’obuwangaazi bwa bbaatule bikwatagana mu butonde n’obulungi bw’ekizigo kino.
Okusoomoozebwa okusookerwako okuva mu kwekwata obubi mulimu:
1. Okukutula:Mu kiseera ky’enkola y’okugerageranya oba ekisannyalazo ekiddiŋŋanwa-enzirukanya y’okufuuwa, okunyigirizibwa kw’ebyuma ne lithium-okuyingiza okugatta kuyinza okuleeta ekizigo okwawukana ku kipande. Kino kitaataaganya amakubo g’amasannyalaze, ekivaako obusobozi obw’amangu okuggwaawo.
2. Okwongera okuziyiza munda:Okukwatagana okubi wakati w’ekintu ekikola n’ekintu ekikung’aanya ekiriwo kati kireeta obuziyiza bw’amasannyalaze obw’amaanyi, okukendeeza ku maanyi agafuluma n’okukola ebbugumu eritayagalwa.
3. Ebikyamu mu kukola:Okwekwata okutamala kiyinza okuleeta enjatika z’okusiiga, ebituli, n’okufuuyira enfuufu mu kiseera ky’okusalasala n’okukwata, okwongera ku bungi bw’ebisasiro n’obukuumi bw’okukosa.
4. Okulemererwa nga tekunnatuuka:Delamination ne high resistance bye bikulu ebiyamba okukendeeza ku bulamu bw’enzirukanya n’obulamu n’okudduka okw’ebbugumu okuyinza okubaawo.
Enkola ez’ennono okulongoosa okwekwata, gamba ng’okukozesa layers ezisiba enzito oba ebirungo ebisookerwako eby’eddagala, zitera okujja n’obusuubuzi-nga okukendeera kw’amaanyi g’amaanyi oba okuleeta obucaafu.
Enkola ya Corona: Enkyukakyuka y’amaanyi ag’okungulu .
Obujjanjabi bwa corona bulungi-teknologiya wa pulasima ow’empewo amanyiddwa ng’akozesa okufulumya kwa vvulovumenti okw’ekika ekya waggulu-Okufulumya empewo eyetoolodde ekintu eky’okungulu. Ku battery electrode foils, enkola eno etuwa enkyukakyuka ey’amaanyi era entuufu kungulu.
Engeri gye kikola:
Nga ekipande ky’ekyuma kiyita ku kizimbulukusa ekiri ku ttaka wansi wa siteegi ya corona treater, ekisannyalazo kya frequency eky’ekika ekya waggulu-efulumya ekifulumya corona ekifugibwa. Okufulumya kuno kutondawo plasma erimu ion, obusannyalazo, ne molekyu ezicamufu (nga ozone). Ebika bino eby’amaanyi bwe bitomeragana n’oludda lw’ekipande, ebintu ebikulu bibiri bibaawo:
1. Ku nguluOkukola ku ngulu:Plasma eggyawo bulungi obucaafu obuva mu biramu n’ebitundu by’ensalo ebinafu, n’eraga ekyuma ekitaliiko kamogo.
2. FunctionalFunctionalization: Ekisinga obukulu, enkola esimba ebibinja by’emirimu egy’enjawulo egy’enjawulo (okusingira ddala haidrokisi [-OH], kaboni [c=o], ne kabokisi [-COOH) ku ngulu w’ekipande.
Enkyukakyuka eno okuva ku low-amaanyi, non-ngulu ku ngulu wa polar okudda ku high-amaanyi, polar surface y’enkola enkulu ey’okulongoosa okunywerera.
Lwaki Ebijjanjabi bya Corona eby'omulembe birungi nnyo okukola bbaatule .
Ebintu eby’omulembe ebya Corona ebikoleddwa mu mulimu gwa bbaatule biwa enkizo ez’enjawulo ku bikozesebwa ebikulu ne tekinologiya ow’enjawulo:
Obutuufu & Obumu:Enkola ez’omulembe zirina dies ezikutuddwamu ebitundutundu ezisobozesa okufuga okwa nnamaddala-Time okubuna obugazi bw’omukutu. Kino kikakasa buli milimita ya FOIL, omuli n’empenda, efuna omutendera gw’obujjanjabi ogutuukiridde, omukulu, omukulu mu kukola kw’obusannyalazo obutakyukakyuka.
Enzirukanya ya Ozone:Enkola z’okusaanyawo ozone ezigatta era ezikola obulungi zikakatako. Enkola zino zikyusa ozone (O₃) okudda mu oxygen (O2), okukakasa embeera y’okukoleramu etali ya bulabe n’okutuukiriza amateeka amakakali agakwata ku butonde bw’ensi.
Obuyonjo & obutali -obucaafu:Okwawukanako ne chemical primers, obujjanjabi bwa corona tebyongerako bintu bigwira ku foil. Ye nkola enkalu, ey’omubiri emalawo obulabe bw’okuleeta obucaafu obuyinza okukosa obutebenkevu bw’amasannyalaze oba kemiko y’obutoffaali.
mu -Line Speed & Scalability:Ekoleddwa olw’okuyiringisibwa waggulu-Speed Roll-okuyitira-ennyiriri z’okufulumya, ebikolagana n’eby’omulembe bisobola okukola ku sipiidi ezisukka 100 m/min, ekizifuula ezituukira ddala ku kukola mu bungi nga gigafactoriaseries.
REAL-Okulondoola obudde:Abajjanjabi abasoosootofu bakwatagana n’ebikozesebwa mu kwekenneenya enkola okulondoola n’okuwandiika emitendera gy’obujjanjabi (obupimiddwa mu Dynes/cm), nga bawa okulondoola okujjuvu n’okukakasa omutindo.
Okukwata ku nkola ya bbaatule n’okuwangaala .
Okugatta ekyuma ekijjanjaba ekirungo kya corona eky’omulembe mu layini y’okukola ebyuma ebikola amasannyalaze kivaamu emigaso egy’obutereevu era egy’okupima:
Okufukirira n’okusiiga ebinywezeddwa:A treated, high-nergy surface ekkiriza aqueous-based electrode slurry okusaasaana kyenkanyi n’okufukirira foil ddala, ekivaamu okusinga coating thickness n’okumalawo obulema.
Amaanyi g’okwesiiga aga waggulu:Ebibinja ebikola eby’enjuba (polar functional groups) ku foyiro bikola ensengekera ya covalent ey’amaanyi ne haidrojeni n’ebisiba bya polimeeri mu kikuta. Kino kireeta enkolagana ey’omukwano, ewangaala eziyiza okukutuka mu kiseera ky’okuvuga obugaali n’ebbugumu erisukkiridde.
Obusobozi bw’emiwendo obulongooseddwa:Nga tukendeeza ku buziyiza bw’okukwatagana ku FOIL-Okusiiga, okujjanjaba kwa corona kwanguyiza okutambuza obusannyalazo mu bwangu, okusobozesa omulimu omulungi ogw’okucaajinga n’okufulumya.
Obulamu bw’obugaali obugaziyiziddwa:Nga okunyweza okunywevu kuziyiza okufiirwa kw’ebintu ebikola, bbaatule ekuuma obusobozi bwayo n’obulungi bw’enzimba mu bikumi n’ebikumi ebirala enzirukanya.
Okwongera ku makungula g’amakolero:Okukendeeza ku kusenya n’okuddamu okukola olw’obulema mu kusiiga butereevu okukendeeza ku nsaasaanya y’okufulumya n’okwongera ku throughput.
Mu bufunzi
Mu mbeera y’okuvuganya okw’amaanyi ey’okutereka amaanyi ag’omulembe, okutumbula obuwangaazi n’obwesigwa bwa buli kitundu kye kisinga obukulu. Obujjanjabi bwa Corona obw’omulembe tebukyali mutendera gwa kwesalirawo gwokka; Tekinologiya wa maanyi nnyo asobozesa okukola bbaatule y’omulembe oguddako{1}}Generation Battery Manufacturing. Mu musingi okugonjoola okusoomoozebwa kw’okunyweza ku kikolo kyakwo, kuwa amaanyi abakola ebintu okuvaamu obukuumi, okuwanvuwa-okuwangaala, n’okusingawo-battery ezikola. Nga bwe tusika ensalo za bbaatule z’amawanga ezigumu-n’eddagala eddala ery’ekipya, obwetaavu bw’okufuga okw’omu maaso okutaliiko kamogo kujja kukoma ku kukula, kunyweza omulimu gw’omutendesi wa Corona ow’omulembe ng’ejjinja ery’oku nsonda mu nkyukakyuka y’amaanyi amayonjo.
