01 - lithium iron phosphate e bonts'a mokhoa o ntseng o phahama

Lithium betri e na le melemo ea boholo bo nyane, boima bo bobebe, ho tjhaja ka potlako le ho tšoarella. E ka bonoa ho tsoa ho betri ea mohala oa thekeng le betri ea koloi. Har'a tsona, betri ea lithium iron phosphate le ternary material battery ke makala a mabeli a maholo a lithium battery hajoale.

Bakeng sa litlhoko tsa polokeho, lebaleng la likoloi tsa baeti le likoloi tse nang le morero o khethehileng, betri ea matla ea lithium iron phosphate e nang le litšenyehelo tse tlase, theknoloji ea sehlahisoa e batlang e holile le e sireletsehileng e sebelisitsoe ka sekhahla se phahameng. The ternary lithium battery e nang le matla a phahameng a khethehileng e sebelisoa haholo tšimong ea likoloi tsa baeti. Liphatlalatsong tse ncha, karolo ea libeteri tsa lithium iron phosphate tšimong ea likoloi tsa baeti e eketsehile ho tloha ka tlase ho 20% pele ho hoo e ka bang 30%.

Lithium iron phosphate (LiFePO4) ke e 'ngoe ea lisebelisoa tsa cathode tse sebelisoang hangata bakeng sa libeteri tsa lithium-ion. E na le botsitso bo botle ba mocheso, ho monya mongobo o fokolang le ts'ebetso e ntle ea potoloho ea tefiso tlasa boemo bo felletseng. Ke sepheo sa lipatlisiso, tlhahiso le nts'etsopele tšimong ea matla le polokelo ea matla li-betri tsa lithium-ion. Leha ho le joalo, ka lebaka la khaello ea sebopeho sa eona, betri ea lithium-ion e nang le lithium iron phosphate kaha thepa e ntle e na le conductivity e fokolang, sekhahla sa ho phalla butle ha lithium ion, le ts'ebetso e mpe ea ho ntša mocheso ka mocheso o tlase. Sena se fella ka hore likoloi tsa pele tse nang le lithium iron phosphate li theohe, haholo-holo maemong a tlase a mocheso.

Bakeng sa ho batla katleho ea mamello, haholoholo kamora hore leano la lithuso tsa likoloi tse ncha tsa matla li fane ka litlhoko tse phahameng bakeng sa mileage ea mamello ea koloi, letsoalo la matla, tšebeliso ea matla le likarolo tse ling, leha betri ea lithium iron phosphate e lula 'marakeng pejana, ternary lithium. betri e nang le matla a phahameng a matla e fetohile 'maraka o mocha oa likoloi tsa baeti. Ho ka bonoa phatlalatso ea morao-rao ea hore le hoja karolo ea betri ea lithium iron phosphate tšimong ea likoloi tsa baeti e tsoetse pele, karolo ea lithium ternary battery e ntse e le hoo e ka bang 70%.

02 - polokeho ke molemo o moholo ka ho fetisisa

Nickel cobalt aluminium kapa nickel cobalt manganese hangata e sebelisoa e le lisebelisoa tsa anode bakeng sa libeteri tsa ternary lithium, empa mosebetsi o phahameng oa thepa ha o tlise matla a matla a matla feela, empa o boetse o tlisa likotsi tse phahameng tsa tšireletso. Lipalopalo tse sa phethahalang li bonts'a hore ka selemo sa 2019, palo ea likotsi tsa likoloi tse ncha e ile ea boleloa ka makhetlo a 14 ho feta ea 2018, 'me lihlahisoa tse kang Tesla, Weilai, BAIC le Weima li bile le likotsi tse latellanang.

E ka bonoa ho tloha kotsi hore mollo o hlaha haholo-holo ts'ebetsong ea ho tjhaja, kapa hang ka mor'a ho tjhaja, hobane betri e tla phahama mocheso nakong ea ts'ebetso ea nako e telele. Ha mocheso oa betri ea ternary lithium o feta 200 ° C, thepa e ntle e bonolo ho senyeha, 'me karabelo ea oxidation e lebisa ho baleha ka potlako le ho tuka ho matla. Sebopeho sa olivine sa lithium iron phosphate se tlisa botsitso ba mocheso o phahameng, 'me mocheso oa eona o balehang o fihla ho 800 ° C, le tlhahiso e fokolang ea khase, kahoo e batla e sireletsehile. Ke ka lebaka leo, ho ipapisitse le menahano ea polokeho, libese tse ncha tsa matla ka kakaretso li sebelisa libeteri tsa lithium iron phosphate, ha libese tse ncha tsa matla tse sebelisang libeteri tsa ternary lithium li sa khone ho kena lethathamong la likoloi tse ncha tsa matla bakeng sa papatso le ts'ebeliso.

Haufinyane tjena, likoloi tse peli tsa motlakase tsa Changan Auchan li amohetse betri ea lithium iron phosphate, e fapaneng le likhoebo tse tloaelehileng tsa likoloi tse shebaneng le likoloi. Mefuta e 'meli ea Changan Auchan ke SUV le MPV. Xiong zewei, motlatsi oa mookameli-kakaretso oa Setsi sa Lipatlisiso sa Chang'an Auchan, o ile a bolella moqolotsi oa litaba: “Sena se bontša hore Auchan o kene ka molao mehleng ea matla a motlakase ka mor’a lilemo tse peli tsa boiteko.”

Mabapi le hore na ke hobane'ng ha betri ea lithium iron phosphate e sebelisoa, Xiong o re polokeho ea likoloi tse ncha tsa matla e 'nile ea e-ba e' ngoe ea "mahlaba a bohloko" a basebelisi, hape e amehile haholo ke likhoebo. Ha ho nahanoa ka sena, pakete ea betri ea lithium iron phosphate e tsamaisoang ke koloi e ncha e qetile teko ea moeli ea ho baka mollo o fetang 1300 ° C, - 20 ° C boemo ba mocheso o tlase, 3.5% ea tharollo ea letsoai, 11 kn khatello ea kantle, joalo-joalo. ., 'me ba fihletse "bane ba sa tšabe" tharollo ea ts'ireletso ea betri ea "ho se tšabe mocheso, ho se tšabe serame, ho se tšabe metsi, ho se tšabe tšusumetso".

Ho ea ka litlaleho, Changan Auchan x7ev e na le enjene e sa feleng ea magnete e nang le matla a 150KW, e nang le mamello ea lik'hilomithara tse fetang 405 le betri ea bophelo bo bolelele e nang le makhetlo a 3000 a ho tjhaja cyclic. Ka mocheso o tloaelehileng, ho nka halofo ea hora feela ho tlatselletsa sebaka sa mamello sa lik'hilomithara tse fetang 300. "Ha e le hantle, ka lebaka la boteng ba tsamaiso ea matla a ho tsosolosa matla, mamello ea koloi e ka fihla lik'hilomithara tse 420 tlas'a maemo a sebetsang a litoropong." Xiong a eketsa.

Ho ea ka leano le lecha la nts'etsopele ea indasteri ea motlakase (2021-2035) (Sets'oants'o sa maikutlo) se fanoeng ke Lekala la indasteri le theknoloji ea tlhahisoleseling, thekiso e ncha ea likoloi tsa motlakase e tla etsa karolo ea 25% ka 2025. Ho ka bonoa hore karolo ea likoloi tse ncha tsa matla li tla tsoela pele ho eketseha nakong e tlang. Boemong bona, ho kenyeletsoa Chang'an Automobile, likhoebo tsa setso tse ikemetseng tsa likoloi li potlakisa moralo oa 'maraka o mocha oa likoloi.
