Kupititsa patsogolo Kugwira Ntchito ndi Kukolola: Udindo Wofunika Kwambiri pa Chithandizo cha Corona mu Lithium-Kupanga Ma Electrode a Ion Battery
Kukankhira magetsi padziko lonse lapansi kwapangitsa kuti pakhale zovuta zambiri zokhudza kagwiridwe ka ntchito, chitetezo, ndi mtengo-kayendetsedwe ka mphamvu zamabatire a lithiamu-ion (Li{2}}ion). Pakatikati pa batire yapamwamba-yomwe imagwira ntchito kwambiri pamakhala ma elekitirodi-pamene pali zinthu zambirimbiri zomwe zimakutidwa pazitsulo zopyapyala zachitsulo. Ubwino wa njira yokutirayi ndiyofunika kwambiri, ndipo imodzi mwazinthu zofunika kwambiri, koma zomwe nthawi zambiri zimanyalanyazidwa, masitepe ndikusintha kwapamwamba kudzera pamankhwala a corona.
The Adhesion Challenge mu Electrode Manufacturing
Li-maelekitirodi a batri a ion amapangidwa pogwiritsa ntchito slurry-zosakanizika za zinthu zomwe zimagwira ntchito (monga, NMC, LFP, Graphite Graphite), zowonjezera zowonjezera, ndi polima binder{4}}pa chotolera chamakono (kawirikawiri aluminiyumu ya cathode ndi mkuwa wa anode). Chophimba chonyowachi chimawumitsidwa mu uvuni kuti chisungunuke chisungunuke.
Vuto lalikulu lagona pa zomwe zili pamwamba pa zojambula zazitsulo. Zopangidwazo zimakhala ndi hydrophobic ndipo zimakhala ndi mphamvu zochepa pamtunda, zomwe zimapangitsa kuti zisagwirizane ndi matope amadzi kapena zosungunulira{1}}zochokera ku slurry. Kusakhazikika bwino kungayambitse:
Electrode Delamination:Chigawo chogwira ntchito chimasiyana ndi zojambulazo panthawi ya kalendala (kukanikiza) kapena kupukuta kwa selo.
Kuchuluka Kwa Magetsi:Kusagwirizana kosagwirizana pakati pa zinthu zomwe zimagwira ntchito ndi wosonkhanitsa panopa kumalepheretsa kuyenda kwa ma elekitironi.
Kutha Kwa Mphamvu ndi Kutha Kwa Mphamvu:Delaminated particles kukhala electrochemically osagwira ntchito, kuchepetsa mphamvu ndi kuonjezera kukana mkati.
Kulephera Kwambiri:Tizidutswa tating'onoting'ono tating'onoting'ono tating'ono tating'onoting'ono tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono timene timayambitsa kutentha.
Kuti athetse mavutowa, opanga ayenera kupititsa patsogolo mphamvu ya pamwamba pa zojambulazo kuti zitsimikizidwe kuti zikhale zonyowa bwino komanso zolimba, zomatira zofanana za slurry.
Kodi Corona Treatment ndi chiyani?
Chithandizo cha Corona ndi ukadaulo wa mumlengalenga wa plasma womwe umagwiritsa ntchito -mphamvu yamagetsi yotulutsa mphamvu kwambiri kusinthiratu zinthu ndi mankhwala popanda kusintha kuchuluka kwake.
Dongosolo lodziwika bwino lochizira corona lili ndi:
1. Jenereta wa Electrode/HV:Amapanga-ma frequency, okwera{1}}mphamvu yamagetsi.
2. Wodzigudubuza Pansi:Chophimba ndi dielectric material (mwachitsanzo, ceramic, silicone labala).
3. Kusiyana kwa Air:Danga lopapatiza pakati pa ma elekitirodi ndi chodzigudubuza momwe ukonde wa gawo lapansi umadutsa.
Kutulutsa kwamagetsi kumapangitsa kuti mamolekyu a mpweya alowe mumphako, akupanga madzi amadzi a m'magazi owundana,{0}}otsika omwe amakhala ndi ma ayoni, ma elekitironi, ndi mitundu ina ya okosijeni yomwe imagwira ntchito kwambiri (monga ozoni).
Momwe Chithandizo cha Corona chimasinthira Mawonekedwe a Battery Foil
Pamene zitsulo zachitsulo zikudutsa m'munda wa plasma, njira ziwiri zazikulu zimachitika:
1. Kuyang'anira Pamwamba & Kuchulukitsa Mphamvu:
Madzi a m'madzi a m'magazi amawombera pamwamba pa chojambulacho, ndikuphwanya mamolekyu a maselo ndikupanga malo atsopano, omwe amatha kuchitapo kanthu. Izi zimawonjezera mphamvu ya pamwamba pa zojambulazo, ndikuzisintha kuchokera ku hydrophobic kupita ku hydrophilic. A apamwamba pamwamba mphamvu amalola slurry kufalikira wogawana ndi kupanga kukhudzana wapamtima, chofunika kwambiri adhesion.
2. Pang'ono-Kusokoneza & Kuyeretsa:
Ma ions amphamvu amatulutsa pamwamba pamtunda wa microscopic, kupanga malo okulirapo ogwira ntchito. Kulira pang'ono kumeneku-kumapereka "anchor points" zambiri pa binder mu slurry, kupititsa patsogolo kulumikiza kwa makina. Panthawi imodzimodziyo, ndondomekoyi imachotsa zonyansa zosaoneka ngati mafuta, ma oxides, ndi zothandizira zothandizira zomwe zingathe kukhala ngati malire ofooka.
Zotsatira zake zimakhala zowoneka bwino, -zopatsa mphamvu zambiri, komanso zowoneka bwino zowoneka bwino kuti zokutira.
Ubwino Wa Chithandizo cha Corona Pamabatire a Li{0}}Ion Batteron
Kuphatikiza mankhwala a corona mumzere wopanga ma electrode kumapindulitsa kwambiri:
Kulimba Kwapamwamba Kwambiri:Imaletsa kusungunuka panthawi yokonza kunsi kwa mtsinje komanso nthawi yonse ya moyo wa batri, kupititsa patsogolo kukhulupirika kwamakina.
Zovala Zovala Zowoneka bwino:Imawonetsetsa kuti malaya amatope molingana popanda kutsitsa-kunyowetsa kapena kupanga mapini, zomwe zimapangitsa kuti ma elekitirodi azigwira ntchito mosasinthasintha.
Kuthekera kwa Mtengo ndi Moyo Wozungulira:Pakuwonetsetsa kuti magetsi alumikizana bwino pakati pa tinthu tating'onoting'ono tomwe timatolera pano, chithandizo cha corona chimachepetsa kukana kwapakati, komwe ndikofunikira pakuchapira mwachangu komanso moyo wautali.
Kuchulukitsa Zokolola:Kuchepetsa zinyalala chifukwa cha zopindika zokutira kumachepetsa mwachindunji ndalama zopangira.
Kugwirizana ndi Aqueous Binders:Pamene makampani akupita ku kukonza amadzimadzi ogwirizana ndi chilengedwe, chithandizo cha corona chimakhala chofunikira kwambiri kuti tikwaniritse milingo yomatira yofanana ndi zosungunulira zakale-zotengera.
Kuwuma, Njira Yapompopompo:Mosiyana ndi ma chemical primers kapena flame treatment, ndiwaukhondo, osayanika nthawi, zomwe zimapangitsa kuti zikhale zoyenera-kuthamanga,{1}}ku{2}kugudubuza mizere yopangira.
Kulondola kwa Mabatire Otsatira-Otsatira
Pamaukadaulo apamwamba a batire monga silicon-anodi kapena mabatire olimba-olimba, ntchito ya mainjiniya apamwamba imakhala yofunika kwambiri. Tinthu tating'onoting'ono ta silicon timakulitsa kuchuluka kwa voliyumu panthawi yanjinga, ndikuyika kupsinjika kwakukulu pamagwirizano ndi omwe akusonkhanitsa. Mawonekedwe amphamvu, a corona-otetezedwa ndi ofunikira kuti magetsi azilumikizana bwino komanso osasunthika podutsa-zozimitsa.
Mapeto
M'malo opikisana kwambiri opanga mabatire, kupindula pang'ono pakuchita bwino ndi zokolola zimatanthauzira kukhala phindu lalikulu lazamalonda. Chithandizo cha Corona si njira yokhayo yomwe mungachitire koma ndi luso lothandizira kupanga mabatire odalirika, -amphamvu-amphamvu kwambiri-ya ma ion. Popereka kusintha kolondola, koyendetsedwa bwino, komanso koyenera, zimatsimikizira kuti zomangira batirezi-maelekitirodi-amapangidwa kuti azigwira ntchito bwino kwambiri, atetezeke, komanso azikhala ndi moyo wautali, zomwe zimathandizira tsogolo la kuyenda ndi kusunga mphamvu.
