Kune 2021, hapana kupokana kuti kuchave nenzvimbo yakawanda uye yakawanda yakasiya-siyana yemusika application.

Muna 1997, apo musayendisiti weAmerica Gudinaf akawana uye akasimbisa kuti olivine-based lithium iron phosphate (LFP) inogona kushandiswa se electrode yakanaka, aisagona kufungidzira kuti nzira yakadaro yehunyanzvi rimwe zuva “ichashandiswa zvakanyanya” muChina.

Muna 2009, China yakatanga chirongwa chemotokari 1,000 10 mumaguta gumi, uye inoronga kuvandudza maguta gumi gore negore mukati memakore matatu, guta rimwe nerimwe richiparura motokari itsva dzinokwana chiuru. Panyaya yekuchengeteka uye hupenyu hurefu, mota zhinji nyowani dzesimba, kunyanya mota dzevatyairi, dzinoshandisa lithium iron phosphate mabhatiri.

Kubva ipapo, iyo lithium iron phosphate tekinoroji nzira yakatanga kudzika midzi muChina uye inoramba ichikura.

Tichirangarira kuvandudzwa kwemabhatiri e-lithium iron phosphate muChina, iyo yakaiswa simba rebhatiri yakawedzera kubva ku0.2GWh muna 2010 kusvika 20.3GWh muna 2016, kuwedzera kwezana mumakore manomwe. Mushure me100, ichadzikama pa7GWh pagore.

Kubva pakuona kwemugove wemusika, chikamu chemusika che lithium iron phosphate chakaramba chiri pamusoro pe70% kubva muna 2010 kusvika muna 2014. Zvisinei, mushure me2016, nekuda kwekugadziriswa kwemitemo yekubatsira uye kubatana pakati pesimba remagetsi, lithium iron phosphate mabhatiri akatanga kutonhora. mumusika, zvishoma nezvishoma zvichiwedzera kubva kune inopfuura 70% yemusika isati yasvika 2014. Muna 2019, yakaderera kusvika pasi pe15%.

Munguva iyi, lithium iron phosphate mabhatiri akagamuchirawo kusahadzika kwakawanda, uye akambofanana nekudzokera shure, uye pakatove netsika yekusiya lithium iron phosphate. Kuseri kwekuchinja uku kunoratidzawo kuti pamberi pa2019, musika unovimba zvakanyanya nepolicy.

Panyaya yehunyanzvi hwekuita uye mutengo, inogona kuratidza kusimudzira uye kukura kwemaindasitiri kwe lithium iron phosphate bhatiri tekinoroji kune imwe nhanho. Mumakore gumi apfuura, simba remagetsi rakawedzera neavhareji ye10% pagore, uye mari yakaderera ne9% pagore.

ANCH technical chief engineer Bai Ke anofanotaura kuti panosvika 2023, kuwedzera kwesimba resimba re lithium iron phosphate zvishoma nezvishoma kunenge kunosvika 210Wh/kg, uye mutengo uchadonha kusvika 0.5 yuan/Wh.

2020 inguva yekushanduka kwe lithium iron phosphate mabhatiri

Kutanga muna 2020, iyo yakambonyarara lithium iron phosphate bhatiri yatanga kutora uye kupinda mukukura kutsva.

Iyo logic kumashure inonyanya kusanganisira:

Chokutanga pane zvose, motokari itsva dzemagetsi dzinomiswa, uye mitsara yakasiyana-siyana yezvigadzirwa uye teknolojia yakatanga kuwana nzira dzavo; chechipiri, mune imwe chiyero che5 g base zviteshi, zvikepe, michina yekuvaka uye mamwe misika, zvakanakira lithium iron phosphate mabhatiri akakurumbira, uye matsva akavhurwa. Mikana yemusika; chechitatu, nekuwedzera kwekushambadzira kwemusika webhatiri, iyo ToC yekupedzisira bhizinesi inotsigira mitsva yekukura mapoinzi, iyo inopa nyowani sarudzo dze lithium iron phosphate mabhatiri.

Iwo matatu anonyanya kunetseka maitiro emhando ari mumunda wemotokari dzemagetsi, Tesla Model 3, BYD Han Chinese uye Hongguang miniEV, iyo yese ine lithium iron phosphate mabhatiri, ayo anounzawo fungidziro huru mumunda wemotokari dzemagetsi. Mota dzine maapplication adzo mune ramangwana.

Sezvo musika unotanga kuenda kure kure nematongerwo uye uchienda kumusika chaiwo, mikana yelithium iron phosphate mabhatiri inozovhurwa zvakare.

Kubva pamaonero emusika data, iyo yakaiswa yemotokari lithium iron phosphate inotarisirwa kusvika 20Gwh muna 2020. Pamusoro pezvo, kutakura kwe lithium iron phosphate mabhatiri mumusika wekuchengetedza simba kunotarisirwa kusvika kunosvika 10Gwh.

Makore gumi matsva emikana ye lithium iron phosphate mabhatiri

Kutarisana ne2021, hapana kupokana kuti lithium iron phosphate mabhatiri anovhura nzvimbo yakawanda mune akawanda akasiyana emusika maapplication.

Mukubatanidzwa kwemagetsi emagetsi emagetsi, maitiro ekufambisa kwenyika uye magetsi emotokari hazvigadziriswi. Kuiswa kwemagetsi kwezvikepe kuri kuwedzerawo, uye zviyero zvakakodzera zviri kuramba zvichivandudza; panguva imwecheteyo, misika yemagetsi yemagetsi inotanga kuedza. Izvi zvigadzirwa zvichatora imwe chikamu mumusika welithium iron phosphate bhatiri.

Munda wekuchengetedza simba uchave wechipiri nhandare yehondo yelithium iron phosphate mabhatiri. Kuchengetedzwa kwesimba kunonyanyo kupatsanurwa kuita hombe-yesimba rekuchengetedza yakasanganiswa negedhi remagetsi uye diki-mwero simba rekuchengetedza rinomiririrwa ne5G base zviteshi, izvo zvinozoita basa rinotungamira mumusika welithium iron phosphate bhatiri application.

Pamusoro pezvo, mumisika yemashandisirwo ari kusimukira, inosanganisira forklift yemagetsi, mopeds yemagetsi, data center backup, elevator backup, magetsi emidziyo yekurapa uye zvimwe zviitiko, zvinounza mimwe mikana uye nzvimbo yelithium iron phosphate mabhatiri.

Musika wekusiyana-siyana, kusimukira kwekusiyanisa kwechigadzirwa

Misika yakasiyana-siyana yakaisawo mberi zvakasiyaniswa zvinodiwa zvemabhatiri e lithium, mamwe anoda hupenyu hurefu hwebhatiri, mamwe anoda kuwanda kwesimba, uye mamwe anoda kuita kwakafara tembiricha. Kunyangwe lithium iron phosphate mabhatiri anoda budiriro yakasiyaniswa kuti isangane nezvinodiwa uye marwadzo emhando dzakasiyana dzekushandisa.

ALCI Technology yakavambwa muna Chivabvu 2016, uye yagara yakanamatira kune lithium iron phosphate tekinoroji nzira. Achivavarira kudiwa kwemusika mune ramangwana, Baike yakaunza tekinoroji yekuvandudza nzira yeAlCI mumunda we lithium iron phosphate mabhatiri.

Mugwara rekuwedzera kusimba kwesimba, nguva yekukurumidza kutsvaga simba density yapfuura, asi serudzi rwemutakuri wesimba, kusimba kwesimba ndicho chiratidzo chehunyanzvi icho chinofanira kutarisana nacho.

Kuti agadzirise dambudziko iri, Anchi yakagadzira yakarongeka yakakwenenzverwa gobvu electrode, iyo inobvisa yakakwirira yemukati kuramba uye kukwira kwekushisa kwebhatiri nekuenzanisa polarization ye electrode plate. Inogona kuita kuti bhatiri resimbi-lithium rive nehupenyu hurefu uye huwandu hwesimba repamusoro. Huremu hwehuremu hwemabhatiri e-lithium iron hwakavakirwa pahunyanzvi uhu hunodarika 190Wh/Kg, uye vhoriyamu inodarika 430Wh/L.

Kuti isangane nezvinodiwa zvemabhatiri emagetsi munzvimbo dzakaderera tembiricha, ANch yakagadzirawo tembiricha yakaderera lithium iron phosphate mabhatiri. Kuburikidza nekubatanidzwa kwepasi-viscosity superelectrolyte, ion/electronic superconducting network, isotropic graphite, ultrafine nanometer lithium iron nemamwe matekinoroji, bhatiri rinogona kushanda zvakajairika munzvimbo yakaderera yekushisa.

Mukuwedzera, mukugadzirwa kwemabhatiri ehupenyu hurefu, kuburikidza ne-low lithium kushandiswa kwemagetsi asina kunaka, high stability positive electrodes, uye electrolyte self-repair technology, zvinopfuura 6000 cycles ye lithium iron phosphate mabhatiri akawanikwa.
