Lipotso Tse Botsoang Hangata
Ke eng e etsang hore silicon e be betere ho feta graphite bakeng sa anode ea betri?
Monyetla oa mantlha oa Silicon o sebopehong sa eona sa athomo-athomo e 'ngoe le e 'ngoe ea silicon e khona ho tlama ho fihla ho 3.75 liathomo tsa lithium, ha liathomo tse tšeletseng tsa khabone ka graphite li tlama athomo e le 'ngoe feela ea lithium. Sena se fetolela matla a theoretical makhetlo a 10 (3,600-4,200 mAh/g khahlano le 372 mAh/g), e nolofalletsang libeteri ho boloka matla a mangata ka boima bo tšoanang le molumo o ka bang nyane.
Hobaneng ha silicon anode e sa nkela graphite sebaka ka botlalo?
Tšitiso ea mantlha ke silicon ea 300-400% ea katoloso ea molumo nakong ea ho tjhaja, e bakang khatello ea maikutlo, ho phatloha ha likaroloana, le tahlehelo ea matla ka potlako. Leha lik'hamphani li thehile li-nanowires, li-composites, le li-binders tse khethehileng ho laola katoloso, litharollo tsena li eketsa ho rarahana ha tlhahiso le litšenyehelo. Phetoho e etsahala butle-butle-ho qala ka li-anode tse nyalisitsoeng tse kopanyang silicon le graphite, ebe li leba meralo e ka sehloohong ea silicon ha theknoloji e ntse e hola le sekala sa tlhahiso.
Libetri tsa silicon anode li bitsa bokae ha li bapisoa le libeteri tse tloaelehileng?
Lisebelisoa tsa hona joale tsa silicon anode li bitsa chelete e ka bang 750,000 CNY ka tonne e le 'ngoe ha e bapisoa le litheko tse thehiloeng ke graphite. Sena se fetolela 10-20% litjeho tse holimo tsa pakete ea betri ka 2024-2025. Leha ho le joalo, litšenyehelo li fokotseha ka potlako e le sekala sa tlhahiso. Likhakanyo tsa indasteri li fana ka maikutlo a hore libeteri tse nyalisitsoeng tsa silicon-graphite li tla fihla ho lekana litšenyehelo le graphite e hloekileng ka 2027-2030 bakeng sa lits'ebetso tse tloaelehileng, 'me likarolo tsa premium li tla amoheloa haufinyane.
Na lifeme tse teng tsa betri li ka hlahisa li-anode tsa silicon?
E itšetlehile ka theknoloji. Likhamphani tse kang Group14 le Sila li ralile lisebelisoa tsa tsona tsa silicon ka ho khetheha hore li shebahale le ho sebetsa joalo ka phofshoana ea graphite, e nolofalletsang ho theoha{2}}ka ho nkela sebaka se seng sa ho etsa libeteri ka liphetoho tse nyane haholo. Mokhoa ona o potlakisa ho amoheloa. Ka lehlakoreng le leng, theknoloji ea nanowire ea Amprius e hloka tlhahiso ea thepa e sa lumellaneng le lisebelisoa tse tloaelehileng, ha joale e fokotsa likopo tsa eona ho limmaraka tsa boleng bo phahameng- tse ikemiselitseng ho tsetela mekhoeng e mecha ea tlhahiso.
Ke lisebelisoa life tse tla nka silicon anode pele?
Adoption e latela boleng{{0}ho ipapisitse le tsoelo-pele. Lisebelisoa tsa sefofane le ts'ireletso ({2}}li-drones tse phahameng, lisathelaete) li amohetsoe pele ka lebaka la litlhoko tse feteletseng tsa ts'ebetso le ho mamella litšenyehelo. Lisebelisoa tsa elektroniki tsa bareki (li-smartphones, li-wearable) li ntse li amohela hona joale ka 2024-2025, ka lihlahisoa tse 'maloa tsa khoebo tse fumanehang. Likoloi tsa motlakase li tla bona kamohelo e atileng ea 2025-2027, ho qala ka mefuta ea pele. Libaesekele tsa motlakase, lisebelisoa tsa motlakase, le polokelo ea grid li tla latela ha litšenyehelo li theoha le sekala sa tlhahiso ho fihlela 2027-2030.
Libetri tsa silicon anode li nka nako e kae?
Li-silicon anode tse tsoetseng pele joale li fumana litekanyo tse 800-1,200 ka botlalo{10}}ka nako ea ho lahlela ha li ntse li boloka 80% ea matla, ho ipapisitsoe le litaba tsa silicon le mokhoa oa boenjineri.
