1. Isimiso senqubo ebalulekile
Ekulungiseleleni ama-electrodes ebhethri, inqubo yokufafaza kwe-atomization ye-ultrasonic kungahlukaniswa ngezinyathelo ezi-4 ezibalulekile:
1.1 Ukulungiselela i-electrode slurry: Hlanganisa izinto ezisebenzayo (njengezinhlayiya ze-LifePo₄), ama-Bindes (anjenge-PVDF), ama-ejenti aqhuma (anjenge-nmp amnyama) ukwenza ama-slurry afanayo (okuqukethwe okuqinile kuvame ukuba ngama-spray "izinto eziluhlaza".
1.2 Ukulethwa kweSlurry kanye ne-atomization: I-slurry ihanjiswa ekhanda le-atomization ye-ultrasonic ngokusebenzisa ipompo yokumila ye-eccomision. I-piezoelectric vibrator yekhanda le-atomization iqhubekisa ngobudlova ngaphansi kokuvusa okuphezulu - imvamisa kagesi (imvamisa i-20Khz - I-100KHZ), i-100Kplet iguqulwe yimvamisa: Imvamisa ivaliwe, amaconsi aphakeme).
1.3 Ukulethwa okuqondayo kwamaconsi: amaconsi ama-slurry athile aqhutshwa yigesi yenethiwekhi (njengomoya owomile, i-nitrogen) ukwakha umugqa wesifutho ozinzile, ofafazwe ngokunembile ku-suple collect surce (umqoqi wamanje uvame ukuhanjiswa ngokuqhubekayo ngebhande lokuhambisa).
1.4 Ukwakheka kokomiswa nokumiswa: amaconsi asakazeka ngokushesha futhi akhungatheke ebusweni bomqoka wamanje ukwakha i-coating eqhubekayo, bese ufaka i-solvent), ekugcineni ukhiphe i-electrode), ngokugcina kwakheka ama-microns angu-5).
2. Izinzuzo ezibalulekile ziqhathaniswa nobuchwepheshe be-elektrodi bendabuko ye-electrode
Ekukhiqizeni kwe-elektrode yebhethri, ubuchwepheshe bendabuko (okufana nokugoba okuhlanganisiwe kanye ne-slit coating) kunezinkinga ezifana nokufana okuhle, ukungcola okuphezulu, nokuqukethwe okubuthakathaka okuvuselelayo / okuqukethwe okuqinile okuphezulu. Izinzuzo zokufafaza kwe-atomization ze-ultrasonic zivelele ikakhulukazi:
Into yendaba | Isifutho se-Ultrasonic | Udokotela ojwayelekile / i-slot coating |
Ukufana kwe-coaging | Amaconsi ahamba kahle futhi agxile, ukuphambuka kompetha okuhlanganisiwe kungalawulwa ngaphakathi ± 1%, futhi akukho ziphutha ezifana "nokuqina kwamandla" | Ukuthambekela ekuguqukeni kokubonakala kwe-slurry, ukuphambuka okukhulu kuvame ± 5% - I-10%, futhi impahla ithonyelwa kalula emaphethelweni |
Ukusetshenziswa kwezinto ezibonakalayo | Amaconsi aqondiswa kakhulu, acishe akhululeke kakhulu, futhi izinga lokusetshenziswa lifinyelela kuma-85% - ama-95% (izindleko zezinto ezisebenzayo ziphezulu, ngakho-ke le nzuzo ibalulekile) | I-slurry kulula ukuhlala futhi idonsa, futhi izinga lokusetshenziswa lingama-50% kuphela - 70% |
Ukulawulwa kokuqina kokuqina | I-Ultra - Imbozo emincane (phansi kuya ku-1 micron) ingatholakala ngobukhulu obuguquguqukayo ngokuqhubekayo, ilungele amabhethri aphezulu wamandla wamandla (ama-coatings anciphile afushanise izindlela ze-Ion zokuphazamiseka) | Kunzima ukulungiselela i-Ultra - Izambatho Ezincanyana <10 ama-microns, kanye nobubanzi bokulungiswa kosayizi buncane |
Ukuqina okuguquguqukayo | Iyakwazi ukuphatha okuqukethwe okuqinile (> 60%), i-viscosity ephezulu (> 1000cp) Slurries, kunciphise ukusetshenziswa kwe-solvent (okuthe xaxa kwemvelo) | Ukuzivumelanisa nezimo ezingezinhle kokuqukethwe okuqinile okuqinile / okuphezulu okuphezulu kwe-slurry, kulula ukuvala imbobo ye-coating |
Ukulimala komqoqi wamanje | Akukho othintana naye ochwepheshe (ikhanda le-atomizer alithinti umqoqi wamanje), elifanele abaqoqi abanciphile kakhulu (njenge-foil yethusi ngaphansi kwe-6μM) | I-scraper ixhumana ngqo nomqoqi wamanje, ongabhala kalula umqoqi omncane wamanje. |
Ukusetshenziswa kokufafaza kwe-atomization ye-ultrasonic emkhakheni wamabhethri kususwe elabhuland kuya enkulu -
3.1 I-Lithium - I-Ion Battery Electrode Coating
I-electrode enhle: ukuhlanganisa izinto zokwakha i-ternary (NCM), i-lithium iron phosphate (LFP), njll. Ebusweni be-aluminium foil, ikakhulukazi elungele ukuphakama - I-Nickel Ternary (njenge-NCM811) - Lolu hlobo lwezinto ezibonakalayo lunezidingo eziphakeme kakhulu zokufana, uma kungenjalo kulula ukudala ukubaleka okushisayo ngenxa yokusabela kwasendaweni okungalingani.
I-Electrode Engalungile: I-Graphito ye-COAGS ne-Silicon - Izinto ezisekelwe ebusweni beFoil yeCopper (Silicon - Okusekelwe Kwe-electrodes ezingezinhle kulula ukwandisa ukugqashuka ngesikhathi sokujikeleza).
Izinzuzo: Thuthukisa ukuvumelana kwe-electrode force density (i-supmucation desity ukuphambuka, ukunciphisa "isikhala se-polarization" ngesikhathi sokushaja ibhethri nokukhipha, futhi kunwetshwe ngo-20% - 30%).
I-3.2 Fuel Cell Catalyst ungqimba ungqimba
Ingxenye esemqoka yamaseli kaphethiloli (njengamaseli we-hydrogen Fuel), "Membrane Electrode (Mea)", idinga ukuhlanganiswa ngePlatinamu - Kususelwa ku-Catalysts ngaphezulu kwe-Proton Exchanges Mempbranes (ebiza kakhulu). Ukufafaza kwe-atomization ye-ultrasonic kungahle ku-athotize i-slurry ye-catalyst (Platinum Particle Displion) ibe ngo-5
3.3 Kubili okuqinile - Ibhethri le-electrolyte le-electrolyte le-electrolyte
I-electrolyte ye-solid - amabhethri wombuso (njenge-sulfide ne-oxide alectroly electrolyte) idinga ukwakha ungqimba oluncane oluncane (1 - ama-microns aqhubekayo) endaweni ye-electrode. Ukufafaza kwe-atomization ye-ultrasonic kungakugwema "ukulimala kwengcindezi" yendabuko yendabuko, kuqinisekiswe ukuthi ungqimba lwe-electrolyte luyaqhekeka - Mahhala, futhi uthuthukise ukusebenza kahle kwe-Ion.
