Tšebeliso ea Graphite Battery Felt ho Libetri tsa Phallo
Libetri tsa phallo, haholo-holo libetri tsa phallo ea vanadium redox (VRFB) le libetri tsa phallo ea zinc-bromine, li batlisisitsoe haholo 'me li sebelisoa mahlaleng a polokelo ea matla. Li boloka le ho ntša matla ka lintho tse sebetsang tse qhibilihisitsoeng ka har'a electrolyte, e leng se li fang nako e telele ea bophelo le bokhoni bo boholo ba polokelo ea matla ha li bapisoa le libetri tsa setso. Moralong oa libetri tsena, felt ea betri ea graphite hangata e sebelisoa likarolong tsa electrode, haholo-holo moo electrolyte e phallang e sebelisanang le thepa ea electrode.
Ho tsamaisa motlakase ho hoholo ha graphite felt ke molemo o ka sehloohong ts'ebelisong ea eona libetering tsa phallo. Libetering tsa phallo, karabelo ea electrochemical e etsahala pakeng tsa electrolyte le li-electrode, kahoo ho tsamaisa motlakase ha li-electrode ho bohlokoa ts'ebetsong ea betri. Jwalo ka thepa ea electrode, graphite felt e ka khothaletsa motsamao oa li-ion ka har'a electrolyte ka katleho le ho netefatsa phetiso e sebetsang ea li-electron, e leng se ntlafatsang ts'ebetso ea betri ea ho tjhaja le ho ntša motlakase.
Ho feta moo, graphite felt e bapala karolo ea bohlokoa taolong ea mocheso ka har'a libeteri tsa phallo. Nakong ea ts'ebetso ea libeteri tsa phallo, mocheso oa kahare oa hlahisoa. Ho tsamaisa mocheso hantle ha graphite felt ho thusa ho qhala mocheso ona, ho thibela betri ho chesa haholo le ho netefatsa hore e sebetsa ka har'a mocheso o motle. Bokhoni bona ba taolo ea mocheso ha bo thuse feela ho lelefatsa bophelo ba betri empa hape bo ntlafatsa polokeho ea eona, ho fokotsa kotsi ea ho hloleha ha betri ka lebaka la mocheso o feteletseng.
Tšebeliso ea Graphite Battery Felt Liseleng tsa Mafura
Lisele tsa mafura ke lisebelisoa tse fetolelang matla a lik'hemik'hale ka ho toba hore e be matla a motlakase ka liketso tsa electrochemical, tse sebelisoang haholo likoloing tsa motlakase, phepelo ea motlakase ea bekapo, le litsamaiso tsa matla a tsosolositsoeng. Tšebeliso ea betri ea graphite e utluoang liseleng tsa mafura haholo-holo e itšetlehile ka karolo ea eona e le lera la khase (GDL) le thepa ea electrode. Bohlokoa ba eona bo bonahala haholo liseleng tsa mafura tsa membrane ea phapanyetsano ea proton (PEMFC).
Liseleng tsa mafura, graphite felt e sebetsa e le lera la ho hasana ha khase (GDL), e ikarabellang bakeng sa ho aba likhase tse arabelang ka ho lekana tse kang haeterojene le oksijene holim'a li-electrode, ha ka nako e ts'oanang e sebetsa e le sehokelo sa ho tsamaisa motlakase. Ka lebaka la ho tsamaisa motlakase hantle, graphite felt e ka fetisetsa lielektrone tse hlahisoang ka hare ho sele ho ea potolohong ea kantle ka katleho, e leng se nolofalletsang tlhahiso ea matla a motlakase. Sebopeho sa eona se nang le masoba se boetse se nolofalletsa ho hasana ha khase le ho tsamaisa motlakase ka motlakase ka motlakase, ho netefatsa hore liketso tsa electrochemical liseleng tsa mafura li tsoela pele ka katleho.
Graphite e utluoang liseleng tsa mafura ha e hloke feela ho fana ka motlakase o motle, empa e tlameha ho ba le khanyetso e ntle ea ho bola le ts'ebetso ea mocheso o phahameng. Kaha lisele tsa mafura li sebetsa libakeng tse nang le mocheso o phahameng le tse senyang, botsitso ba lik'hemik'hale le botsitso ba mocheso ba graphite bo etsa hore e be khetho e ntle. E ka sebetsa ka botsitso maemong a feteletseng ka nako e telele, e qoba ho senyeha ha ts'ebetso ka lebaka la botsofali ba thepa kapa ho bola.
Ho feta moo, graphite e utluwang diseleng tsa mafura le yona e thusa ho ntlafatsa bokgoni ba karabelo ka sebopeho sa yona se entsweng hantle. Tlhophiso le ho arolwa ha difaeba tsa graphite ha di ntlafatse matla a yona a mechini feela empa hape di ntlafatsa bokgoni ba phallo ya kgase. Ka ho lokisa ka nepo porosity le sebopeho sa sebopeho sa graphite e utluwang, matla a tlhahiso le tshebetso ya disele tsa mafura di ka ntlafatswa le ho feta.
