Lilemong tsa morao tjena,libeteri tsa lithium-ionli fetohile mehloli ea bohlokoa ea matla bakeng sa lisebelisoa tse fapaneng tsa elektroniki. Leha ho le joalo, matshwenyeho a polokeho a potileng dibetri tsena a tsositse puisano ka dikotsi tse ka bang teng. Lithium Iron Phosphate (LiFePO4) ke k'hemistri e khethehileng ea betri e fumaneng tlhokomelo ka lebaka la polokeho ea eona e ntlafetseng ha e bapisoa le libeteri tse tloaelehileng tsa Li-ion. Ho fapana le maikutlo a mang a fosahetseng, libeteri tsa lithium iron phosphate ha li hlahise ho phatloha kapa tšoso ea mollo. Sehloohong sena, re ikemiselitse ho senya boitsebiso bona bo fosahetseng le ho hlakisa litšobotsi tsa polokeho ea libeteri tsa LiFePO4.
Ithute ka libeteri tsa lithium iron phosphate
LiFePO4 betri ke betri e tsoetseng pele ea lithium-ion e sebelisang lithium iron phosphate e le thepa ea cathode. Khemistri ena e fana ka melemo e mengata, ho kenyelletsa le matla a phahameng a matla, bophelo ba nako e telele, sekhahla se tlase sa ho itšehla thajana, 'me haholo-holo, ts'ireletseho e matlafalitsoeng. Ka moralo, libeteri tsa lithium iron phosphate ka tlhaho li tsitsitse haholoanyane 'me li na le kotsi e tlase ea ho baleha ha mocheso-e leng ntho e ka lebisang ho phatloha le mollo.
Saense ka mor'a polokeho ea betri ea LiFePO4
E 'ngoe ea mabaka a ka sehloohong a etsang hore libeteri tsa LiFePO4 li nkoe li sireletsehile ke sebopeho sa tsona se tsitsitseng sa kristale. Ho fapana le libeteri tse ling tsa lithium-ion tseo lisebelisoa tsa tsona tsa cathode li nang le lithium cobalt oxide kapa lithium nickel manganese cobalt (NMC), LiFePO4 e na le moralo o tsitsitseng haholoanyane. Sebopeho sena sa kristale se lumella ho senyeha ha mocheso hamolemo nakong ea ts'ebetso ea betri, ho fokotsa kotsi ea ho chesa haholo le ho baleha ha mocheso.
Ho feta moo, k'hemistri ea betri ea LiFePO4 e na le mocheso o phahameng oa ho bola ha o bapisoa le lik'hemik'hale tse ling tsa Li-ion. Sena se bolela hore libeteri tsa LiFePO4 li ka mamella mocheso o phahameng ntle le ho senyeha ha mocheso, ho eketsa moeli oa tšireletso lits'ebetsong tse fapaneng.
Mehato ea polokeho ho moralo oa betri oa LiFePO4
Mehato e fapaneng ea polokeho e sebelisoa ts'ebetsong ea ho etsa libeteri tsa LiFePO4 ho fokotsa kotsi ea ho phatloha le mollo. Mehato ena e thusa ho ntlafatsa polokeho le ts'epahalo ka kakaretso ea libeteri tsa LiFePO4. Likarolo tse ling tse hlokomelehang tsa ts'ireletso li kenyelletsa:
1. Li-electrolyte tse tsitsitseng: Li-betri tsa LiFePO4 li sebelisa li-electrolyte tse sa cheng, ho fapana le libeteri tse tloaelehileng tsa lithium-ion tse sebelisang li-electrolyte tsa tlhaho tse tukang. Sena se felisa monyetla oa ho chesa electrolyte, e leng ho fokotsang kotsi ea mollo haholo.
2. Sistimi ea tsamaiso ea betri (BMS): Pakete e 'ngoe le e' ngoe ea LiFePO4 ea betri e na le BMS, e nang le mesebetsi e kang ts'ireletso ea ho feta tekano, ts'ireletso ea ho tsoa ho feta, le tšireletso ea potoloho e khutšoanyane. BMS e lula e beha leihlo le ho laola matla a betri, hona joale, le mocheso ho netefatsa ts'ebetso e bolokehileng le e nepahetseng ea betri.
3. Thibelo ea ho baleha ha mocheso: Libetri tsa LiFePO4 ha li na monyetla oa ho baleha ka lebaka la k'hemistri ea tsona e sireletsehileng ka tlhaho. Ha ho na le ketsahalo e feteletseng, fektheri ea lifepo4 betri hangata e eketsa mekhoa ea ts'ireletso ea mocheso, joalo ka li-fuse tsa mocheso kapa matlo a thibelang mocheso, ho fokotsa kotsi le ho feta.
Lisebelisoa le melemo ea betri ea LiFePO4
Libetri tsa LiFePO4 li sebelisoa liindastering tse sa tšoaneng, ho akarelletsa le likoloi tsa motlakase (EVs), polokelo ea matla e tsosolositsoeng, lisebelisoa tsa elektronike tsa bareki, esita le lisebelisoa tsa bongaka. Tšireletseho e ntlafetseng, nako e telele ea bophelo, le ho tšepahala ho etsa hore e be tse loketseng bakeng sa likopo tse boima joalo.
Ha re phethela
Ho fapana le maikutlo a fosahetseng, libeteri tsa LiFePO4 ha li na kotsi ea ho phatloha kapa ho chesa. Sebopeho sa eona se tsitsitseng sa kristale, mocheso o phahameng oa ho senyeha ha mocheso, le mehato ea tšireletso e kenyelletsoeng ts'ebetsong ea tlhahiso e etsa hore e bolokehe ka tlhaho. Ka tlhoko e ntseng e hola ea litharollo tse tsoetseng pele tsa polokelo ea matla, libeteri tsa lithium iron phosphate li behiloe e le khetho e tšepahalang le e bolokehileng bakeng sa liindasteri tse fapaneng. Litaba tse fosahetseng mabapi le polokeho ea betri li tlameha ho rarolloa le tsebo e nepahetseng e khothaletsoe ho netefatsa hore batho ba etsa liqeto tse nepahetseng mabapi le khetho ea matla.
Haeba u thahasella libeteri tsa lithium iron phosphate, u amohelehile ho ikopanya le lifepo4 battery factory Radiance tobala haholoanyane.
