Mathata a betri ea lithium iron phosphate
Ho sa tsotellehe hore na thepa e na le monyetla oa ho sebelisoa le ho ntlafatsa, ntle le melemo ea eona, ntho ea bohlokoa ke hore na thepa e na le mefokolo ea motheo.
Hona joale, lithium iron phosphate e khethiloe ka ho pharaletseng e le thepa ea cathode ea matla a betri ea lithium-ion Chaena.Bahlahlobisisi ba 'maraka ho tsoa mebusong, litsi tsa lipatlisiso tsa mahlale, likhoebo esita le lik'hamphani tsa polokeho li na le tšepo ka thepa ena mme ba e nka e le tataiso ea nts'etsopele ea libeteri tsa lithium-ion tsa matla.Ho ea ka tlhahlobo ea mabaka, ho na le haholo-holo lintlha tse peli tse latelang: Pele, ka lebaka la tšusumetso ea tataiso ea lipatlisiso le nts'etsopele United States, lik'hamphani tsa Valence le A123 United States li ile tsa sebelisa pele lithium tšepe phosphate e le thepa ea cathode. matla a betri ea lithium ion.Taba ea bobeli, lisebelisoa tsa lithium manganate tse nang le libaesekele tse phahameng tsa mocheso le ts'ebetso ea polokelo tse ka sebelisoang bakeng sa libeteri tsa lithium-ion tsa matla ha li so lokisoe Chaena.Leha ho le joalo, lithium iron phosphate le eona e na le mefokolo ea mantlha e ke keng ea hlokomolohuoa, e ka akaretsoang ka tsela e latelang:
1. Ts'ebetsong ea sintering ea ho lokisetsa lithium iron phosphate, ho ka etsahala hore oxide ea tšepe e ka fokotsoa hore e be tšepe e bonolo tlas'a mocheso o phahameng oa ho fokotsa sepakapaka.Iron, e leng ntho ea taboo ka ho fetisisa libetering, e ka baka "micro short circuit" ea libeteri.Lena ke lona lebaka le ka sehloohong leo ka lona Japane e sa sebeliseng thepa ena e le thepa ea cathode ea matla a mofuta oa libeteri tsa lithium ion.
2. Lithium iron phosphate e na le bofokoli bo itseng ba ts'ebetso, joalo ka khatello e tlase ea tamping le compaction density, e bakang matla a tlase a matla a betri ea lithium ion.Ts'ebetso e tlase ea mocheso e futsanehile, le haeba nano ea eona - le ho roala ha carbon ha ho rarolle bothata bona.Ha Dr. Don Hillebrand, mookameli oa Energy Storage System Center ea Argonne National Laboratory, a bua ka ts'ebetso e tlaase ea mocheso oa lithium iron phosphate battery, o ile ae hlalosa e le e tšabehang.Liphetho tsa bona tsa liteko ho betri ea lithium iron phosphate li bonts'itse hore betri ea lithium iron phosphate ha e khone ho khanna likoloi tsa motlakase ka mocheso o tlase (ka tlase ho 0 ℃).Le hoja bahlahisi ba bang ba bolela hore tekanyo ea ho boloka bokhoni ba betri ea lithium iron phosphate e ntle mocheso o tlaase, e tlas'a boemo ba ho fokotseha ho tlaase hona joale le ho fokotseha ho fokolang ha motlakase.Tabeng ena, lisebelisoa li ke ke tsa qala ho hang.
3. Litsenyehelo tsa ho lokisetsa thepa le theko ea ho etsa libeteri li holimo, tlhahiso ea libeteri e tlaase, 'me ho tsitsa ha eona ho fokola.Le hoja thepa ea electrochemical ea thepa e ntlafalitsoe ke nanocrystallization le carbon coating ea lithium iron phosphate, mathata a mang a boetse a tlisitsoe, a kang phokotso ea matla a matla, ntlafatso ea litšenyehelo tsa motsoako, ts'ebetso e mpe ea ts'ebetso ea electrode le tikoloho e thata. ditlhoko.Le hoja likarolo tsa lik'hemik'hale Li, Fe le P ka lithium iron phosphate li ruile haholo 'me theko e tlaase, theko ea sehlahisoa se lokiselitsoeng sa lithium iron phosphate ha se tlaase.Esita le ka mor'a ho tlosa litšenyehelo tsa pele tsa lipatlisiso le nts'etsopele, litšenyehelo tsa ts'ebetso ea thepa ena hammoho le litšenyehelo tse phahameng tsa ho lokisa libeteri li tla etsa hore litšenyehelo tsa ho qetela tsa polokelo ea matla li phahame.
4. Tšebeliso e mpe ea sehlahisoa.Hona joale, ha ho fektheri ea thepa ea lithium iron phosphate Chaena e ka rarollang bothata bona.Ho latela pono ea ho lokisoa ha lintho tse bonahalang, karabelo ea motsoako oa lithium iron phosphate ke karabelo e rarahaneng e fapaneng, ho kenyeletsoa phosphate e tiileng, oxide ea tšepe le letsoai la lithium, selelekela sa khase le ho fokotsa khase.Ts'ebetsong ena e rarahaneng ea karabelo, ho thata ho netefatsa ho lumellana ha karabelo.
5. Litaba tsa thepa ea mahlale.Hajoale, patent ea mantlha ea lithium iron phosphate ke ea Univesithi ea Texas United States, athe patent e koahetsoeng ka carbon e sebelisoa ke batho ba Canada.Lipatente tsena tse peli tsa mantlha li ke ke tsa fetisoa.Haeba litefiso tsa patent li kenyellelitsoe litšenyehelong, theko ea sehlahisoa e tla eketsoa le ho feta.
Ho phaella moo, ho tsoa phihlelong ea R & D le tlhahiso ea libeteri tsa lithium-ion, Japane ke naha ea pele ea ho rekisa libeteri tsa lithium-ion, 'me e' nile ea e-ba teng 'marakeng oa betri ea lithium-ion.Le hoja United States e etella pele lipatlisisong tse ling tsa motheo, ho fihlela joale ha ho na moetsi oa betri ea lithium ion e kholo.Ka hona, hoa utloahala hore Japane e khethe lithium manganate e fetotsoeng e le thepa ea cathode ea mofuta oa matla a betri ea lithium ion.Esita le United States, halofo ea bahlahisi ba sebelisa lithium iron phosphate le lithium manganate e le lisebelisoa tsa cathode tsa matla a mofuta oa lithium ion libeteri, 'me' muso oa federal o boetse o tšehetsa lipatlisiso le nts'etsopele ea mekhoa ena e 'meli.Ka lebaka la mathata a ka holimo, lithium iron phosphate e thata ho sebelisoa haholo e le thepa ea cathode ea matla a betri ea lithium-ion likoloing tse ncha tsa matla le masimo a mang.Haeba re ka rarolla bothata ba ho futsaneha ha libaesekele tse phahameng tsa mocheso le ts'ebetso ea polokelo ea lithium manganate, e tla ba le monyetla o moholo oa tšebeliso ea matla a betri ea lithium-ion ka melemo ea theko e tlaase le ts'ebetso e phahameng.
