Hona joale, litšenyehelo tsa betri ea koloi ea motlakase ka kakaretso ke 30% -40% ea koloi eohle, eo ho ka thoeng ke sesebelisoa sa mantlha!
Hajoale, libeteri tsa motlakase tse sebelisoang ka har'a likoloi tsa motlakase 'marakeng hangata li arotsoe ka mefuta e' meli: libeteri tsa ternary lithium le libeteri tsa lithium iron phosphate. Ka mor'a moo, e re ke hlahlobe ka bokhutšoanyane liphapang le melemo le melemo ea libeteri tsena tse peli:
1. Lisebelisoa tse fapaneng:
Lebaka leo ka lona e bitsoang "ternary lithium" le "lithium iron phosphate" haholo-holo e bua ka likarolo tsa lik'hemik'hale tsa "positive electrode material" ea betri ea matla;
"Ternary lithium":
Lisebelisoa tsa cathode li sebelisa lithium nickel cobalt manganate (Li(NiCoMn) O2) lisebelisoa tsa ternary cathode bakeng sa libeteri tsa lithium. Boitsebiso bona bo kopanya melemo ea lithium cobalt oxide, lithium nickel oxide le lithium manganate, ho etsa tsamaiso ea eutectic ea mekhahlelo e meraro ea lisebelisoa tse tharo. Ka lebaka la phello ea ternary synergistic, ts'ebetso ea eona e felletseng e betere ho feta motsoako ofe kapa ofe oa motsoako o le mong.
"Lithium iron phosphate":
e bua ka libeteri tsa lithium-ion tse sebelisang lithium iron phosphate e le thepa ea cathode. Litšobotsi tsa eona ke hore ha e na lisebelisoa tsa tšepe tsa bohlokoa tse kang cobalt, theko ea thepa e tala e tlaase, 'me mehloli ea phosphorus le tšepe e ngata lefatšeng, kahoo ho ke ke ha e-ba le mathata a phepelo.
kakaretso
Lisebelisoa tsa Ternary lithium lia haella 'me li ntse li phahama ka tsoelo-pele e potlakileng ea likoloi tsa motlakase. Litheko tsa tsona li holimo 'me li thibetsoe haholo ke lisebelisoa tse tala tse holimo. Ena ke tšobotsi ea ternary lithium hajoale;
Lithium iron phosphate, hobane e sebelisa karo-karolelano e tlase ea lirafshoa tse sa tloaelehang / tsa bohlokoa mme haholo-holo e theko e tlase ebile e le ngata, e theko e tlase ho feta libeteri tsa ternary lithium 'me ha e amehe haholo ke lisebelisoa tse tala tse holimo. Ena ke tšobotsi ea eona.
2. Matla a mangata a fapaneng:
"Ternary lithium battery": Ka lebaka la ts'ebeliso ea lisebelisoa tsa tšepe tse sebetsang haholoanyane, matla a matla a betri ea ternary lithium hangata ke (140wh / kg ~ 160 wh / kg), e leng e ka tlaase ho ea betri ea ternary e nang le tekanyo e phahameng ea nickel. 160 w/kg～180 wh / kg); matla a mang a boima a ka fihla ho 180Wh-240Wh/kg.
"Lithium iron phosphate": Matla a matla ka kakaretso ke 90-110 W/kg; Libetri tse ling tse ncha tsa lithium iron phosphate, joalo ka libeteri tsa blade, li na le matla a matla a fihlang ho 120W/kg-140W/kg.
kakaretso
Monyetla o moholo oa "ternary lithium battery" ho feta "lithium iron phosphate" ke matla a eona a phahameng a matla le lebelo la ho tjhaja ka potlako.
3. Ho feto-fetoha ha mocheso o fapaneng:
Ho hanyetsa mocheso o tlase:
Ternary lithium battery: Ternary lithium battery e na le ts'ebetso e ntle haholo ea mocheso o tlase mme e ka boloka hoo e ka bang 70% ~ 80% ea matla a tloaelehileng a betri ho -20°C.
Lithium iron phosphate: Ha e hanyetsane le mocheso o tlase: Ha mocheso o le ka tlase ho -10°C,
Libetri tsa lithium iron phosphate li senyeha kapele haholo. Libetri tsa lithium iron phosphate li ka boloka feela 50% ho isa ho 60% ea matla a tloaelehileng a betri ho -20.°C.
kakaretso
Ho na le phapang e kholo ea ho feto-fetoha ha mocheso pakeng tsa "ternary lithium battery" le "lithium iron phosphate"; "lithium iron phosphate" e hanyetsana le mocheso o phahameng; 'me "ternary lithium battery" e hanyetsanang le mocheso o tlase e na le bophelo bo betere ba betri libakeng tse ka leboea kapa mariha.
4. Linako tse fapaneng tsa bophelo:
Haeba matla a setseng / matla a pele = 80% a sebelisoa e le ntlha ea ho qetela ea teko, teko:
Lipakete tsa betri tsa lithium iron phosphate li na le bophelo bo bolelele ba potoloho ho feta libeteri tsa lead-acid le libeteri tsa ternary lithium. "Bophelo bo bolelele" ba libeteri tsa rona tse kentsoeng ka koloing ke makhetlo a ka bang 300 feela; ternary lithium betri ka theory e ka tšoarella ho fihlela ho makhetlo a 2,000, empa ts'ebelisong ea 'nete, matla a tla senyeha ho isa ho 60% kamora makhetlo a ka bang 1,000; 'me bophelo ba sebele ba libeteri tsa lithium iron phosphate ke linako tse 2000, ho ntse ho e-na le matla a 95% ka nako ena,' me bophelo ba eona ba potoloho ea maikutlo bo fihla ho feta makhetlo a 3000.
kakaretso
Libetri tsa matla ke tsona tse ka sehloohong tsa theknoloji ea libeteri. Mefuta ka bobeli ea libeteri tsa lithium e batla e tšoarella. Ha re bua ka theory, nako ea bophelo ea ternary lithium battery ke 2,000 charge and discharge cycles. Leha re ka e lefisa hang ka letsatsi, e ka nka lilemo tse fetang 5.
5. Litheko li fapane:
Kaha libeteri tsa lithium iron phosphate ha li na lisebelisoa tsa tšepe tsa bohlokoa, theko ea thepa e tala e ka fokotseha haholo. Li-betri tsa lithium tsa Ternary li sebelisa lithium nickel cobalt manganate e le lisebelisoa tse ntle tsa electrode le graphite e le lisebelisoa tse mpe tsa electrode, kahoo litšenyehelo li theko e boima haholo ho feta libeteri tsa lithium iron phosphate.
Betri ea ternary lithium haholo-holo e sebelisa thepa ea ternary cathode ea "lithium nickel cobalt manganate" kapa "lithium nickel cobalt aluminate" e le electrode e ntle, haholo-holo e sebelisa letsoai la nickel, letsoai la cobalt le letsoai la manganese e le lisebelisoa tse tala. "Cobalt element" linthong tsena tse peli tsa cathode ke tšepe ea bohlokoa. Ho ea ka lintlha tse tsoang liwebsaeteng tse amehang, theko ea litšupiso ea lehae ea tšepe ea cobalt ke 413,000 yuan/ton, 'me ka ho fokotseha ha thepa, theko e ntse e phahama. Hona joale, theko ea libeteri tsa ternary lithium ke 0.85-1 yuan / wh, 'me hona joale e ntse e phahama ka tlhokahalo ea' maraka; litsenyehelo tsa libeteri tsa lithium iron phosphate tse se nang lisebelisoa tsa tšepe tsa bohlokoa li ka ba 0.58-0.6 yuan/wh feela.
kakaretso
Kaha "lithium iron phosphate" ha e na litšepe tsa bohlokoa tse kang cobalt, theko ea eona ke makhetlo a 0.5-0.7 feela a betri ea ternary lithium; theko e tlaase ke molemo o moholo oa lithium iron phosphate.
Akaretsa
Lebaka leo ka lona likoloi tsa motlakase li atlehileng lilemong tsa morao tjena 'me li emela tataiso ea nakong e tlang ea nts'etsopele ea likoloi, ho fa bareki phihlelo e molemo ka ho fetisisa, haholo-holo ka lebaka la tsoelo-pele e tsoelang pele ea theknoloji ea betri ea matla.
