Ho fokotsa tšilafalo ea tikoloho e bakoang ke lerōle la graphite le li-electrode tsa litšila, ho hlokahala mokhoa o akaretsang, o akaretsang taolo ea mohloli, tsamaiso ea ts'ebetso, kalafo ea pheletso ea liphaephe le ts'ebeliso ea mehloli. Tse latelang ke mehato e tobileng le lintlha tsa ts'ebetsong:
I. Taolo ea Tšilafalo ea Lerōle la Graphite
Mahlale a ho Fokotsa Lerōle la Mohloli
- Tlhahiso e Kentsweng: Kenya ka botlalo disebediswa tsa ho sebetsana le graphite (mohlala, di-crusher, di-mill, le di-screener) ho fokotsa ho dutla ha lerōle.
- Ho Nkela Mokhoa oa ho Metsi Sebaka: Sebelisa mekhoa ea ho sebetsana le metsi nakong ea ho sila le ho sila, u sebelisa moholi oa metsi ho thibela ho hasana ha lerōle ha u ntse u fokotsa mocheso oa ts'ebetso le ho fokotsa oxidation ea graphite.
- Kgetho ya Thepa e Tala e Lerōle le Tlase: Beha pele thepa e tala ya graphite e nang le boholo bo lekanang ba dikarolwana le lerole le tlase ho fokotsa tlhahiso ya lerole la bobedi nakong ya tshebetso.
Mekhoa ea ho Bokella Lerōle e Ts'ebetsong
- Di-Collector tsa Lerōle tse Sebetsang Haholo: Kenya li-filter tsa mekotla, li-precipitator tsa motlakase, kapa li-arolator tsa sefefo bakeng sa ho hloekisa likhase tse tletseng lerōle ka mekhahlelo e mengata, ho netefatsa hore likhase tse tsoang li fihlela maemo a naha a tikoloho (mohlala, ≤10 mg/m³).
- Moralo oa Mosi o Futhumatsang o Behiloeng Sebakeng: Kenya li-hood tsa mosi sebakeng seo libakeng tsa tlhahiso ea lerōle (mohlala, likoung tsa ho fepa le ho ntša metsi) 'me u li kopanye le litsamaiso tsa khatello e mpe bakeng sa pokello ea lerōle ka nako e loketseng.
- Tlhokomelo e Bohlale: Sebelisa li-sensor tsa mahloriso a lerōle bakeng sa ho lekola mosi o tsoang ka nako ea sebele, ho nolofalletsa ho lokisa moea ka boiketsetso lisebelisoa tsa pokello ea lerōle ho ntlafatsa katleho ea kalafo.
Ho Fumana Lerōle le Tšebeliso
- Ho Sebelisoa Hape bakeng sa Tšebeliso e Ncha: Hlahloba le ho hloekisa lerōle la graphite le bokelloang ke litsamaiso tsa pokello ea lerōle bakeng sa tšebeliso e ncha tlhahisong ea li-electrode kapa e le lintho tse ling tse eketsang (mohlala, litlolo, thepa e tsamaisang motlakase).
- Ho Lahla Hammoho: Kopanya lerōle le ke keng la sebelisoa hape ka ho toba le litšila tse ling tsa indasteri (mohlala, mashala a gangue, mesaletsa) ho hlahisa thepa ea kaho (mohlala, litene, thepa ea motheo oa litsela).
II. Taolo ea Tšilafalo ea Elektrode ea Lithōle
Ho Atolosa Bophelo ba Tšebeletso ea Electrode
- Moralo o Ntlafaditsweng: Ntlafatsa sebopeho sa elektrode (mohlala, masoba a motlakase, ditsela tsa ho tsamaisa motlakase) ka dipalopalo ho ntlafatsa kganyetso ya mocheso le kganyetso ya oxidation.
- Kalafo ea Bokaholimo: Sebelisa theknoloji ea ho kenya kapa ho koahela (mohlala, ho kenya ka asphalt, ho koahela ka silicon carbide) ho ntlafatsa ho tsofala ha bokaholimo le ho hanyetsa ho bola.
- Tlhokomelo e Bohlale: Kenya di-sensor tsa mocheso le kgatello ka hara di-electrode bakeng sa ho lekola boemo ba nako ya sebele, ho thibela ho jara boima ba mmele kapa ho robeha ha mmele ho bakwang ke ho chesa haholo sebakeng seo.
Tlhophiso ea Li-electrode tsa Lithōle le ho Sebelisa Hape
- Ho Qhaqha ho se Nang Kotsi: Ho sila li-electrode tse silang ka mechine le ho arola lihokelo tsa tšepe (mohlala, linate tsa koporo) ho tsoa likotoana tsa graphite ho sebelisoa karohano ea makenete le ea pneumatic.
- Tšebeliso e Phahameng:
- Graphite e Hloekileng Haholo: Hloekisa ka kalafo ea mocheso o phahameng (≥2,500°C) bakeng sa tšebeliso ea li-electrode tsa boleng bo holimo kapa thepa ea semiconductor.
- Graphite e Bohloeki bo Mahareng ho isa ho bo Tlase: E sila bakeng sa ho sebelisoa e le sesebelisoa sa ho tsosolosa tšepe kapa e kopanye le li-resin ho hlahisa lihlahisoa tsa graphite (mohlala, litiiso, hlobo).
- Litšila tse setseng: Kopanya le letsopa ho hlahisa litene tse hanang kapa u li sebelise e le mokhoa oa ho tlatsa motheo oa tsela.
Mahlale a Tsosoloso ea Lisebelisoa
- Ho Hloekisa Lik'hemik'hale: Qhibilihisa litšila (mohlala, silicon, tšepe) ka har'a li-electrode tsa litšila ho sebelisoa litharollo tsa acid-base, ebe ho lateloa ke ho sefa le ho omisa ho fumana phofo ea graphite e hloekileng haholo.
- Graphitization ea Mocheso o Phahameng: Likaroloana tsa elektrode tse futhumatsang tlas'a tšireletso ea khase e sa sebetseng (2,000–3,000°C) ho tsosolosa sebopeho sa kristale ea graphite le ho ntlafatsa conductivity.
- Khatiso ea 3D: Kopanya phofo ea elektrode ea litšila le li-binder 'me u sebelise khatiso ea 3D ho etsa likarolo tsa graphite tse ikhethileng, ho fokotsa litšila tsa thepa.
III. Mehato e Felletseng ea Tsamaiso
- Litlhahlobo tsa Tlhahiso e Hloekileng: Etsa litekolo khafetsa ho khetholla lits'ebetso tsa tšilafalo e phahameng le ho nts'etsapele merero ea ntlafatso (mohlala, ho nkela lisebelisoa tse nang le lerōle le phahameng sebaka, ho ntlafatsa mesebetsi).
- Ho Latela Melao: Khomarela ka tieoTekanyetso e Kopaneng ea ho Ntša Mosi ea Lintho Tse Silafatsang Moea(GB 16297) leMolao oa Thibelo le Taolo ea Tikoloho ea Tšilafalo ea Litšila tse Tiilengho netefatsa hore ho lahloa lerōle le li-electrode tse litšila ka nepo.
- Mohlala oa Moruo o Selikalikoe: Sebelisana le likhoebo tse holimo le tse tlase ho theha marang-rang a ho sebelisa hape graphite, ho theha "ketane ea indasteri ea tlhahiso-tšebeliso-ea-tlhahiso-bocha" e koetsoeng.
- Koetliso le Tšireletso ea Basebetsi: Matlafatsa koetliso ea temoso ea tikoloho bakeng sa basebetsi le ho fana ka lisebelisoa tsa tšireletso tsa botho (mohlala, limaske tsa lerōle, likhalase tsa mahlo) ho fokotsa likotsi tsa bophelo bo botle mosebetsing.
IV. Lithuto tsa Nyeoe
- Liindasteri tsa Toray (Japane): Ho kentswe tshebetsong mekgwa ya ho sila ka metsi le ho thiba metsi ka tsela e koetsoeng ho fokotsa mosi wa lerole o sebetsanang le graphite ho fihlela ka tlase ho 0.5 mg/m³.
- Fangda Carbon (Chaena): E hahile mohala oa graphitization oa mocheso o phahameng bakeng sa li-electrode tsa litšila, e sebelisa hape lithane tse 12,000 tsa li-electrode tsa graphite tse tsosolositsoeng selemo le selemo le ho fokotsa mesi ea CO₂ ka lithane tse ka bang 80,000.
- SGL Carbon (Jeremane): Ho ntshetsitswe pele theknoloji ya ho hlwekisa ka laser ho nkela sebaka sa ho tjhesa ka dikhemikhale, ho fihlella kalafo ya bokahodimo ba electrode e se nang tšilafalo le ho fokotsa tlhahiso ya metsi a ditshila ka 90%.
Ka ho ntlafatsa mahlale, ho ntlafatsa tsamaiso, le ho khothaletsa tšebeliso ea mehloli, tšusumetso ea tikoloho ea lerōle la graphite le li-electrode tsa litšila e ka fokotsoa haholo ha e ntse e theha boleng ba moruo le ho khanna phetoho e tala ea indasteri.
