Bakeng sa 2021, ha ho na pelaelo ea hore ho tla ba le sebaka se eketsehileng le lits’ebetso tse fapaneng tsa mebaraka.

Ka 1997, ha rasaense oa Amerika Gudinaf a fumana le ho tiisa hore olivine-based lithium iron phosphate (LFP) e ka sebelisoa e le electrode e ntle, o ne a ke ke a nahana hore tsela e joalo ea theknoloji ka letsatsi le leng e tla “sebelisoa haholo” Chaena.

Ka 2009, China e ile ea thakhola projeke ea makoloi a 1,000 10 metseng e 10, ’me e rera ho ntšetsa pele metse e 1,000 selemo se seng le se seng nakong ea lilemo tse tharo, motse o mong le o mong o hlahisa likoloi tse ncha tse XNUMX XNUMX tsa matla. Mabapi le polokeho le bophelo bo bolelele, likoloi tse ngata tse ncha tsa matla, haholo likoloi tsa baeti, li sebelisa libeteri tsa lithium iron phosphate.

Ho tloha ka nako eo, tsela ea theknoloji ea lithium iron phosphate e qalile ho mela Chaena ‘me e ntse e tsoela pele ho hōla.

Ha re hopola nts’etsopele ea libeteri tsa lithium iron phosphate Chaena, matla a kentsoeng a libeteri a eketsehile ho tloha 0.2GWh ka 2010 ho ea ho 20.3GWh ka 2016, keketseho ea makhetlo a 100 ka lilemo tse 7. Ka mor’a 2016, e tla tsitsa ho 20GWh ka selemo.

Ho ea ka pono ea karolo ea ‘maraka, karolo ea’ maraka ea lithium iron phosphate e ntse e le ka holimo ho 70% ho tloha 2010 ho ea ho 2014. Leha ho le joalo, ka mor’a 2016, ka lebaka la phetoho ea maano a liphallelo le kamano pakeng tsa matla a matla, libeteri tsa lithium iron phosphate li ile tsa qala ho pholile. ‘marakeng, butle-butle e eketseha ho tloha ho feta 70% ea’ maraka pele ho 2014. Ka 2019, e theohile ho ea tlase ho 15%.

Nakong ena, libeteri tsa lithium iron phosphate le tsona li fumane lipelaelo tse ngata, ‘me li kile tsa tšoana le ho khutlela morao,’ me ho bile ho bile le mokhoa oa ho lahla lithium iron phosphate. Ka morao ho phetoho ena e boetse e bontša hore pele ho 2019, ‘maraka o itšetlehile haholo ka leano.

Mabapi le ts’ebetso ea tekheniki le litšenyehelo, e ka bonts’a nts’etsopele le kholo ea indasteri ea theknoloji ea betri ea lithium iron phosphate ho isa bohōleng bo itseng. Lilemong tse 10 tse fetileng, matla a matla a matla a eketsehile ka karolelano ea 9% ka selemo, ‘me litšenyehelo li theohile ka 17% ka selemo.

Moenjiniere ea ka sehloohong oa ANCH Bai Ke o bolela esale pele hore ka 2023, keketseho ea matla a matla a lithium iron phosphate e tla lieha butle ho ea ho 210Wh / kg, ‘me litšenyehelo li tla theohela ho 0.5 yuan / Wh.

2020 ke sebaka sa phetoho bakeng sa libeteri tsa lithium iron phosphate

Ho qala ka 2020, betri ea lithium iron phosphate e kileng ea khutsa e se e qalile ho nka le ho kenya potoloho e ncha ea kholo.

Maikutlo a ka morao haholo a kenyelletsa:

Pele ho tsohle, likoloi tse ncha tsa matla li emisitsoe, ‘me mela e fapaneng ea lihlahisoa le theknoloji e se e qalile ho iphumanela litsela; ea bobeli, ka tekanyo e itseng ea liteishene tsa motheo tsa 5 g, likepe, mechine ea kaho le limmaraka tse ling, melemo ea libeteri tsa lithium iron phosphate li hlahella, ‘me tse ncha li butsoe. Menyetla ea ‘maraka; ea boraro, ka papatso e ntseng e eketseha ea ‘maraka oa betri, khoebo ea ho qetela ea ToC e tšehetsa lintlha tse ncha tsa kholo, tse fanang ka likhetho tse ncha bakeng sa libeteri tsa lithium iron phosphate.

Mehlala e meraro e amehang ka ho fetesisa e sebakeng sa likoloi tsa motlakase, Tesla Model 3, BYD Han Chinese le Hongguang miniEV, tseo kaofela li nang le libeteri tsa lithium iron phosphate, tse tlisang mohopolo o moholo tšimong ea likoloi tsa motlakase. Likoloi li na le ts’ebeliso ea tsona nakong e tlang.

Ha ‘maraka o qala ho tloha hole le maano le ho ea’ marakeng oa ‘nete, menyetla ea libeteri tsa lithium iron phosphate e tla buloa le ho feta.

Ho latela pono ea lintlha tsa ‘maraka, matla a kentsoeng a likoloi tsa lithium iron phosphate e lebelletsoe ho fihla ho 20Gwh ka 2020. Ho feta moo, thomello ea libeteri tsa lithium iron phosphate marakeng oa polokelo ea matla e lebelletsoe ho fihla hoo e ka bang 10Gwh.

Lilemo tse leshome tse ncha tsa menyetla ea libeteri tsa lithium iron phosphate

Ha re shebane le 2021, ha ho na pelaelo hore libeteri tsa lithium iron phosphate li tla bula sebaka se eketsehileng lits’ebetsong tse fapaneng tsa mebaraka.

Motlakase o kopantsoeng oa tsamaiso ea matla, mokhoa oa lipalangoang tsa mobu le motlakase oa likoloi o ke ke oa fetoha. Ho kenngoa ha motlakase likepeng le hona ho ntse ho potlaka, ‘me litekanyetso tse amehang li lula li ntlafala; ka nako e ts’oanang, ‘maraka oa lifofane tsa motlakase o qala ho leka. Lihlahisoa tsena li tla ba le karolo e itseng ‘marakeng oa betri ea lithium iron phosphate.

Sebaka sa polokelo ea matla e tla ba lebala la bobeli la ntoa bakeng sa libeteri tsa lithium iron phosphate. Polokelo ea matla e arotsoe haholo ka polokelo e kholo ea matla e kopantsoeng le grid ea matla le polokelo e nyane ea matla e emeloang ke liteishene tsa 5G, tse tla bapala karolo e ka sehloohong ‘marakeng oa kopo ea betri ea lithium iron phosphate.

Ntle le moo, limmarakeng tsa likopo tse ntseng li hlaha, ho kenyeletsoa lifereko tsa motlakase, li-mopeds tsa motlakase, bekapo ea setsi sa data, bekapo ea lifti, phepelo ea motlakase ea lisebelisoa tsa bongaka le maemo a mang, e tla tlisa menyetla e itseng le sebaka sa libeteri tsa lithium iron phosphate.

Phapang ea ‘maraka, nts’etsopele ea phapang ea lihlahisoa

Limmaraka tse fapaneng li boetse li hlahisitse litlhoko tse fapaneng tsa libeteri tsa lithium, tse ling li hloka bophelo bo bolelele ba betri, tse ling li hloka matla a mangata a matla, ‘me tse ling li hloka ts’ebetso e pharalletseng ea mocheso. Le libeteri tsa lithium iron phosphate li hloka ntlafatso e fapaneng ho fihlela litlhoko le lintlha tsa bohloko tsa maemo a fapaneng a ts’ebeliso.

ALCI Technology e thehiloe ka May 2016, ‘me esale e khomarela tsela ea theknoloji ea lithium iron phosphate. E ipapisitse le tlhoko ea ‘maraka ea kamoso, Baike e hlahisitse tataiso ea nts’etsopele ea theknoloji ea AlCI lebaleng la libeteri tsa lithium iron phosphate.

Mabapi le ho eketseha ha matla a matla, nako ea ho lelekisa matla a matla a matla e se e fetile, empa joalo ka mofuta oa sesebelisoa sa matla, letsoalo la matla ke letšoao la tekheniki leo le tlamehang ho tobana le lona.

E le ho rarolla bothata bona, Anchi e hlahisitse electrode e teteaneng e hlophisitsoeng ka mokhoa o hlophisitsoeng, e felisang khanyetso e phahameng ea ka hare le ho phahama ha mocheso oa betri ka ho leka-lekanya polarization ea poleiti ea electrode. E ka etsa hore betri ea iron-lithium e be le bophelo bo bolelele le matla a phahameng a matla. Boima ba matla ba libeteri tsa tšepe tsa lithium tse thehiloeng ho theknoloji ena bo feta 190Wh/Kg, ‘me molumo o feta 430Wh/L.

E le ho finyella litlhoko tsa ts’ebeliso ea libeteri tsa matla maemong a mocheso o tlaase, ANch e boetse e thehile libethe tse tlaase tsa lithium iron phosphate. Ka ho kopana ha superelectrolyte e tlaase-viscosity, ion / electronic superconducting network, isotropic graphite, ultrafine nanometer lithium iron le theknoloji e meng, betri e ka sebetsa ka tloaelo sebakeng sa mocheso o tlaase.

Ho phaella moo, ho nts’etsopele ea libeteri tsa nako e telele, ka tšebeliso e tlaase ea lithium e sa sebeliseng li-electrode tse mpe, li-electrode tse ntle tse tsitsitseng, le theknoloji ea ho itokisa ea electrolyte, ho fihletsoe li-cycle tse fetang 6000 tsa libeteri tsa lithium iron phosphate.
