Ha ke tsebe hore na betri ea lithium e ntse e khanna koloi ea motlakase joang.

Mongoli : Iflowpower -Mofani oa Seteishene sa Motlakase se nkehang

Betri ke moea oa likoloi tsa motlakase, ha ho na libeteri, likoloi tsa motlakase li ke ke tsa bontša phapang ea hae. Ka kakaretso ea litšenyehelo tsa koloi ea motlakase, betri e ka ikarabella bakeng sa 30% -45% ea litšenyehelo, likoloi le li-account tsa motlakase tsa motlakase bakeng sa 20% -25%, 'mele le likarolo tse ling li nka 20%. Sena se bontša kamoo betri e leng bohlokoa kateng! Ka hona, betri e boetse ke ntho eo baetsi ba likoloi ba ka sehloohong ba tsepamisang maikutlo ho eona.

Kahoo, ke mofuta ofe oa betri o bohlokoa hona joale 'marakeng? Ho na le mefuta e mene ea mefuta e mene: betri ea lithium ion ea mahlakore a mararo, betri ea lithium iron phosphate ion, betri ea lead-acid le betri ea lithium-ion. Batri ea lithium-ion e nang le likarolo tse tharo ke betri ea lithium-ion e nang le likarolo tse tharo, joalokaha lebitso le bolela, e thehiloe holim'a letsoai la nickel, letsoai la cobalt, letsoai la manganese e le lisebelisoa tse ntle tsa electrode e le ntho e ntle. lisebelisoa tsa elektrode, 'me thepa ea ternary e sebelisoa e le electrode e ntle. Tšireletseho ea betri e phahametse betri ea lithium cobalt ion, e leng ntho ea bahlahisi ba betri ba hona joale.

Ho sa tsotellehe hore na u reka ntho e itseng, moreki o tla hlahloba melemo le mathata a eona ha a ntse a reka, 'me o tla rata ho reka melemo le melemo ea thepa, empa melemo le melemo ea betri ea lithium-ion tse tharo li hlakile haholo, ho thata ho li sebelisa. karolo ya ho ahlola. Melemo e ikhethang ea betri ea lithium-ion ke hore boima ba matla a hae a boima bo phahame haholo ho feta ba mefuta e meng ea libeteri, ho bolelang hore boima bo tšoanang ba betri ea lithium-ion ea likarolo tse tharo ha bo bapisoa le libeteri tse ling, bophelo ba betri ea eona. e ngata ho feta. Leha ho le joalo, sebopeho ha sea tsitsa ho latela mocheso o phahameng, e le hore tšireletso e be thata ho e laola, 'me litšenyehelo li batla li le holimo.

Leha batho ba bangata hajoale ba ela hloko le ho sebelisa betri ena, nts'etsopele ea eona e na le tsela e telele e lokelang ho etsoa. Lithium iron phosphate ion battery lithium iron phosphate ion battery ke lithium ion battery e thehiloeng ho lithium iron phosphate e le ntho e ntle ea electrode. E amanang le betri ea lithium-ion e nang le likarolo tse tharo, polokeho ea betri ea lithium phosphate ion e phahame, senotlolo sa PO ka likristale tsa lithium iron phosphate, le haeba ho le thata ho senyeha ha mocheso o phahameng kapa ho feta tekano, 'me e ka ba qosoa ka potlako, e sebedisoang Bophelo bo bolelele.

Ka nako e ts'oanang, lithium ea naha ea heso e ruile, mehloli ea tšepe ea oxide phosphate oxide naheng ea Chaena e boetse e le ngata, e le hore ho be le molemo o motle ho betri ea naha ea heso ea lithium iron ion, kahoo lik'hamphani tsa malapeng li ikemiselitse ho khetha tsoelo-pele le thuto. phosphate ea tšepe. Betri ea lithium-ion, joalo ka BYD, e teng ka har'a betri ena. Moetsong o mocha oa Qin, ke sebelisitse lipatlisiso tsa morao-rao le nts'etsopele ea libeteri tsa ion tsa lithium phosphate.

Betri ena e ekelitse likarolo tsa manganese, 'me matla a eona a matla a fihla botebong ba lisebelisoa tsa ternary,' me a ntlafatsoa haholo bophelong ba betri. Leha ho le joalo, ho na le bothata bo boholo ha beng ba likoloi ba bangata ba tletleba ka matla a motlakase le betri ea betri. Lintlha tsena tse peli hape ke taba ea bohlokoa ea libeteri tsa ion tsa lithium iron phosphate.

Matla a matla a betri ea lithium iron phosphate ion e tlase, e etsang hore molumo o be moholo haholo, 'me betri e na le molumo o monyenyane, e leng se etsang hore bophelo ba betri bo fetohe boto e khutšoanyane,' me betri ha e khone ho hlaphoheloa ka mor'a sekhechana. , e ka lahleloa feela, boleng ba ho tsosolosa bo tlaase haholo, qetellong, betri ena e futsanehile, 'me ho qosoa ha mariha le hona ke bothata bo boholo. Ka hona, haeba BYD e batla ho tsoela pele ho etella pele ka betri, e tla bitsa boiteko bo bongata. Batri ea lithium-cobalt ea cobaltate ke "betri e khethehileng" ea Tesla, e nang le mohaho o tsitsitseng, bokhoni bo phahameng, le ts'ebetso e phahameng ka kakaretso.

E na le matla a betri a matle, empa hobane yuniti e nyane, e etsa koloi Ho feta palo ea libeteri, Tesla e hahile likarolo tse fetang 7,000 tsa mohlala oa Models, 18650, betri ea lithium-ion ea li-yuan tse tharo e lekane. kganna koloi ho matha. Ha mocheso oa betri ka boeena o fihla ho 250-350 ¡ã C, metsoako ea lik'hemik'hale e ka hare e se e qalile ho senyeha, 'me ho tla ba le likotsi tse ngata tsa tšireletso.

Betri e nang le asiti ea lead-acid ke monna ea tsofetseng ka har'a betri. E se e ntse e e-na le histori ea lilemo tse 150, 'me li-electrode tsa eona li bohlokoa ho tsoa ho loto le li-oxide tsa eona. Hajoale, tšebeliso ea libeteri tsa lead-acid e batla e pharaletse ebile e bohlokoa bakeng sa likoloi tsa motlakase tse lebelo le tlase.

Molemo ke hore motlakase o tsitsitse, matla a maholo, 'me mocheso oa mocheso o pharaletseng.
