Boemong ba pele ba &39;maraka oa likoloi tse hloekileng tsa motlakase, libeteri tsa lithium iron phosphate ion ke libeteri tse tloaelehileng. Leha ho le joalo, ka nts&39;etsopele ea betri ea lithium-ion ea matla, betri ea ion ea mahlakore a mararo butle-butle e ile ea nkela betri ea lithium iron ion sebaka. Hoa hlokahala bakeng sa betri ea lithium iron phosphate ion ha e bapisoa le betri ea ternary lithium ion, matla a matla a tlase.

Nakong ea pele ea matla a betri ea lithium-ion, matla a betri ea lithium iron phosphate ion betri pakete ke 100Wh / kg feela, mme matla a matla a betri ea ternary lithium ion a ka fihla ho 140Wh / kg kapa ho feta. Ka ho tsosoa ha thuso e fokolang ea koloi ea motlakase, hammoho le theko e phahameng ea likoloi tse hloekileng tsa motlakase, lekhalo le hlakile ho feta mefuta e tloaelehileng ea mafura. Matla a tlase a matla a tlase, mme betri ea lithium iron phosphate ion e khuts&39;oane bophelong ba betri ha e na molemo.

Ntle le moo, ts&39;ebetso e khahlanong le mocheso o tlase oa betri ea lithium iron phosphate ion le ts&39;ebetso ea ho tjhaja e bapisoa le betri ea ternary lithium ion. Tlas&39;a maemo a batang a mariha, ho fokotseha ha libeteri tsa lithium iron ion ho tla fihla ho feta 50%, hammoho le ts&39;ebetso e liehang ea ho tjhaja, e leng ho tla fokotsa haholo katleho ea ho feta. Ka hona, matla a matla a matla a molemo, &39;me betri ea lithium-ion ea li-yuan tse tharo e batloa butle-butle ke khoebo ea likoloi.

Ka nts&39;etsopele ea &39;maraka, ho na le mefuta e mengata ea bophelo ba betri ea NEDC ho feta 600km. Leha ho le joalo, betri ea lithium-ion e nang le likarolo tse tharo ha e na thuso. Leha ho na le molemo ho matla a matla le ts&39;ebetso ea ho tjhaja, e tlase ho feta betri ea lithium iron phosphate ion bophelong ba potoloho ea betri le bophelo ba potoloho ea betri.

The ternary lithium-ion battery e sebelisoa ka thata ke electrode e ntle, e leng ternary positive material ea lithium nickel-watery oxynumide kapa nickel-cobalt-aluminate, e lakatseha hore e thehoe holim&39;a letsoai la nickel, letsoai la cobalt le letsoai la manganese. Karolo ea cobalt linthong tsena tse peli tse ntle tsa elektrode ke tsa litšepe tsa bohlokoa. Ho ea ka lintlha tsa sebaka sa marang-rang se amehang, litheko tsa tšepe tsa cobalt tsa lehae ke 277,500 yuan / ton, mme ka ho fokotseha ha thepa, theko e ntse e hola.

Hona joale, litšenyehelo tsa betri ea lithium-ion tse tharo-dimensional ke 0.85-1 yuan / WH; Litsenyehelo tsa betri ea lithium iron phosphate ion ntle le likarolo tsa tšepe tse ntle ke 0.58-0 feela.

6 yuan / WH. Ho phaella moo, bophelo ba potoloho ea betri ea lithium ion e nang le likarolo tse tharo e boetse e tšoana le betri ea lithium iron-ion, &39;me palo ea tefiso le ho tsoa ha betri ea phosphate ion ke makhetlo a 2,000. Ka kakaretso ha e sebelisoa lilemo tse 4, boholo ba betri e tla fokotseha, e leng se lebisang ho theko e phahameng ea betri.

Tšireletseho ea betri, ho potlakisa mocheso oa sele ea betri ea ion ea mahlakore a mararo e tlaase, &39;me e fihlile ho pota-pota likhato tse 200,&39; me mocheso ona o tsoa taolong o tla bolokeha. E tlase e tlase. Ka matla a matla a betri ea ternary lithium-ion, likotsi tsa polokeho li khutšoane.

Ha e le hantle, hangata re ka bona likoloi tse hloekileng tsa motlakase litaba tse itlelang feela. Ka hona, polokeho ea betri le eona ke bokuli bo boholo mefuteng ea likoloi tsa motlakase. Ke hobane&39;ng ha u tlameha ho sebelisa betri ea lithium-ion ea mahlakore a mararo? Karolo e ka pele e hlalositse melemo le bofokoli ba betri ea ion ea lithium iron phosphate le betri ea ion ea mahlakore a mararo.

Batho ba bang ba ka ’na ba botsa. Kaha polokeho ea betri ea lithium iron phosphate ion e ntle haholo, bophelo ba potoloho ea betri bo ntse bo le telele, &39;me litšenyehelo li ntse li le tlase, joale Ke hobane&39;ng ha bahlahisi ba bangata ba ntse ba tsitlallela ho kena boemong ba bona ba likoloi tse hloekileng tsa motlakase ho jara betri ea ternary lithium-ion? Ehlile, betri ea ion ea lithium iron phosphate ion e kentsoeng boemong ba ho kena koloing e hloekileng ea motlakase ehlile ke mohopolo o nepahetseng haholoanyane. Leha ho le joalo, matla a hona joale a matla a betri ea lithium iron phosphate ion a tlase, &39;me NEDC e sa feleng ea mefuta ea mefuta ea betri ea mofuta ona e haufi le 200km,&39; me ha ho na thuso ea naha.

Haeba pakete ea betri e lokela ho finyelloa, palo ea lipakete tsa betri e lokela ho eketsoa, ​​​​e leng se lebisang khōlong e ncha ea koloi. &39;Me boholo ba mohlala oa boemo ba ho kena ha bo boholo, kahoo lipakete tse ngata tsa betri ha li khone ho behoa. Ka hona, betri ea hona joale ea phosphate ion e khethoa ka kakaretso ke bese ea motlakase, karete ea leseli la motlakase le mekhoa e meng ea lipalangoang, &39;me ba na le sebaka se eketsehileng bakeng sa betri,&39; me ka lebaka la tsela e tsitsitseng, ha ho hlokahale hore ba nahane ka bophelo ba betri.

Mabapi le polokeho ea betri, batho ha baa lokela ho tšoenyeha haholo. Hona joale, tsamaiso ea khatello e phahameng ea betri ea lithium-ion e nang le likarolo tse tharo le likarolo tse phahameng tsa khatello li fihlile boemong bo phahameng ka ho fetisisa ba IP67 baahi ba se nang metsi le lerōle, esita le metsing a tebileng a 1 a kolobisitsoeng ka metsotso ea 30 betri ntle le tšenyo. Ho feta moo, ha betri e le khutšoanyane, e tletse matla a mangata, &39;me e thulana, tsamaiso e tla itokolla ka mokhoa o ikemetseng phepelo ea matla a matla a matla, le kotsi ea ho itima.

Ho feta moo, ts&39;ebetso e phahameng ea ho tjhaja betri ea lithium ion ea likarolo tse tharo e ka ts&39;ehetsa ho tjhaja sekhahla se seholo, ho ntlafatsa ts&39;ebetso ea ho tjhaja, &39;me boiphihlelo bo tla ba betere. Ho phaella moo, e le ho ntlafatsa tlhōlisano, lik&39;hamphani tse ngata tsa likoloi li hlahisitse leano la ho boloka matla le ho reka hape ho fokotsa bothata ba litšenyehelo tsa betri.
