01 - phosphate ea tšepe ea lithium e bontša mokhoa o ntseng o eketseha

Betri ea lithium e na le melemo ea boholo bo bonyenyane, boima bo bobebe, ho tjhaja kapele le ho tšoarella. E ka bonoa ho tsoa betring ea selefounu le betring ea koloi. Har'a tsona, betri ea lithium iron phosphate le betri ea thepa ea ternary ke makala a mabeli a maholo a betri ea lithium hajoale.

Bakeng sa litlhoko tsa polokeho, lefapheng la likoloi tsa bapalami le likoloi tse reretsoeng merero e khethehileng, betri ea matla ea lithium iron phosphate e nang le theko e tlase, theknoloji ea sehlahisoa se hōlileng tsebong le se sireletsehileng e sebelisitsoe ka sekhahla se phahameng. Betri ea ternary lithium e nang le matla a khethehileng a phahameng e sebelisoa haholo lefapheng la likoloi tsa bapalami. Liphatlalatsong tse ncha, karolo ea libeteri tsa lithium iron phosphate lefapheng la likoloi tsa bapalami e eketsehile ho tloha ho tlase ho 20% pele ho moo ho ea ho hoo e ka bang 30%.

Phosphate ea tšepe ea lithium (LiFePO4) ke e 'ngoe ea lisebelisoa tsa cathode tse sebelisoang haholo bakeng sa libeteri tsa lithium-ion. E na le botsitso bo botle ba mocheso, e monya mongobo o fokolang le ts'ebetso e ntle ea potoloho ea ho ntša tjhaja tlas'a boemo bo felletseng ba ho tjhaja. Ke sepheo sa lipatlisiso, tlhahiso le nts'etsopele lefapheng la libeteri tsa lithium-ion tsa matla le polokelo ea matla. Leha ho le joalo, ka lebaka la moeli oa sebopeho sa eona, betri ea lithium-ion e nang le phosphate ea tšepe ea lithium e le thepa e ntle e na le conductivity e fokolang, sekhahla sa ho hasana butle sa lithium ion, le ts'ebetso e fokolang ea ho ntša tjhaja mochesong o tlase. Sena se fella ka hore likoloi tsa pele tse nang le betri ea lithium iron phosphate li tsamaee butle, haholo-holo maemong a mocheso o tlase.

E le ho batla katleho ea lik'hilomithara tsa mamello, haholo-holo kamora hore leano la lithuso la likoloi tse ncha tsa matla le behe litlhoko tse phahameng tsa lik'hilomithara tsa mamello ea likoloi, bongata ba matla, tšebeliso ea matla le likarolo tse ling, leha betri ea lithium iron phosphate e se e ntse e le teng 'marakeng pejana, betri ea ternary lithium e nang le bongata bo phahameng ba matla butle-butle e fetohile karolo e ka sehloohong ea 'maraka oa likoloi tse ncha tsa bapalami ba matla. Ho ka bonoa ho tsoa tsebisong ea morao-rao ea hore leha karolo ea betri ea lithium iron phosphate lefapheng la likoloi tsa bapalami e eketsehile hape, karolo ea betri ea lithium ternary e ntse e le hoo e ka bang 70%.

02 - polokeho ke molemo o moholo ka ho fetisisa

Aluminium ea nickel cobalt kapa nickel cobalt manganese hangata li sebelisoa e le thepa ea anode bakeng sa libeteri tsa lithium tsa ternary, empa ts'ebetso e phahameng ea thepa ha e tlise feela bongata bo phahameng ba matla, empa hape e tlisa likotsi tse phahameng tsa ts'ireletso. Lipalopalo tse sa fellang li bontša hore ka 2019, palo ea likotsi tsa ho itšunya ha likoloi tse ncha tsa matla e boletsoe ka makhetlo a 14 ho feta ea 2018, 'me lihlahisoa tse kang Tesla, Weilai, BAIC le Weima li hlahisitse likotsi tsa ho itšunya ha motlakase ka tatellano.

Ho ka bonoa kotsing hore mollo o hlaha haholo-holo nakong ea ts'ebetso ea ho tjhaja, kapa hang ka mor'a ho tjhaja, hobane betri e tla nyoloha mochesong 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 bola, 'me karabelo ea oxidation e lebisa ho balehang ka potlako ha mocheso le ho cha ka matla. Sebopeho sa olivine sa phosphate ea tšepe ea lithium se tlisa botsitso bo phahameng ba mocheso, 'me mocheso oa eona o balehang o fihla ho 800 ° C, le tlhahiso e fokolang ea khase, kahoo e sireletsehile haholoanyane. Ke ka lebaka lena hape, ho latela lintlha tsa polokeho, libese tse ncha tsa matla ka kakaretso li sebelisa libeteri tsa phosphate ea tšepe ea lithium, ha libese tse ncha tsa matla tse sebelisang libeteri tsa ternary lithium li sa khone ho kena ka nakoana lethathamong la likoloi tse ncha tsa matla bakeng sa ho khothaletsa le ho sebelisa.

Haufinyane tjena, likoloi tse peli tsa motlakase tsa Changan Auchan li sebelisitse betri ea lithium iron phosphate, e fapaneng le lik'hamphani tse akaretsang tsa likoloi tse shebaneng le likoloi. Mefuta e 'meli ea Changan Auchan ke SUV le MPV. Xiong zewei, motlatsi oa molaoli kakaretso oa Chang'an Auchan Research Institute, o boleletse moqolotsi oa litaba: "sena se bontša hore Auchan e kene ka molao mehleng ea matla a motlakase kamora lilemo tse peli tsa boiteko."

Ha e le mabapi le hore na ke hobane'ng ha betri ea phosphate ea tšepe ea lithium e sebelisoa, Xiong o itse polokeho ea likoloi tse ncha tsa matla esale e le e 'ngoe ea "lintlha tse bohloko" tsa basebelisi, 'me hape ke eona e amehang haholo ke likhoebo. Ha ho nahanoa ka sena, sephutheloana sa betri ea phosphate ea tšepe ea lithium se jeroeng ke koloi e ncha se phethile teko ea moeli ea ho baka mollo o fetang 1300 ° C, - 20 ° C mocheso o tlase o eme, 3.5% tharollo ea letsoai e eme, 11 kN khatello ea kantle, jj., 'me se fihletse tharollo ea polokeho ea betri ea "bane ba sa tšabeng" 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 ea makenete e sa feleng e tsamaisanang le motlakase e nang le matla a phahameng a 150KW, e nang le bolelele ba ho mamella ba fetang 405 km le betri e phelang nako e telele haholo e nang le ho tjhaja ka potoloho ka makhetlo a 3000. Mochesong o tloaelehileng, ho nka halofo ea hora feela ho tlatsa bolelele ba ho mamella ba fetang 300 km. "Ha e le hantle, ka lebaka la boteng ba sistimi ea ho khutlisa matla a braking, mamello ea koloi e ka fihla ho hoo e ka bang 420 km tlas'a maemo a ts'ebetso ea litoropo." Xiong o ekelitse.

Ho ya ka moralo wa ntshetsopele ya indasteri ya dikoloi tse ntjha tsa eneji (2021-2035) (Moralo wa maikutlo) o ntshitsweng ke Lefapha la indasteri le theknoloji ya tlhahisoleseding, thekiso ya dikoloi tse ntjha tsa eneji e tla ba ka bang 25% ka 2025. Ho ka bonwa hore karolo ya dikoloi tse ntjha tsa eneji e tla tswela pele ho eketseha nakong e tlang. Moelelong ona, ho kenyeletswa le Chang'an Automobile, dikgwebo tsa setso tsa dikoloi tse ikemetseng di potlakisa moralo wa mmaraka wa dikoloi tse ntjha tsa eneji.
