Ngo-2021, akungabazeki ukuthi kuzoba nesikhala esiningi kanye nezicelo zemakethe ezihlukene.

Ngo-1997, lapho usosayensi waseMelika uGudinaf ethola futhi eqinisekisa ukuthi i-lithium iron phosphate (LFP) esekelwe ku-olivine ingasetshenziswa njenge-electrode enhle, akazange acabange ukuthi umzila onjalo wezobuchwepheshe ngolunye usuku “uzosetshenziswa kabanzi” e-China.

Ngo-2009, i-China yethula uhlelo lwezimoto ezingu-1,000 10 emadolobheni angu-10, futhi ihlela ukuthuthukisa amadolobha angu-1,000 njalo ngonyaka phakathi neminyaka emithathu, idolobha ngalinye lethule izimoto ezintsha ezingu-XNUMX XNUMX ezisebenza ngamandla. Mayelana nokuphepha nempilo ende, izimoto eziningi ezintsha zamandla, ikakhulukazi izimoto zabagibeli, zisebenzisa amabhethri e-lithium iron phosphate.

Kusukela lapho, umzila wezobuchwepheshe we-lithium iron phosphate usuqalile ukumila eChina futhi uyaqhubeka nokukhula.

Uma sikhumbula ukuthuthukiswa kwamabhethri e-lithium iron phosphate e-China, umthamo ofakiwe wamabhethri ukhuphuke ukusuka ku-0.2GWh ngo-2010 ukuya ku-20.3GWh ngo-2016, okuwukunyuka kwezikhathi eziyi-100 eminyakeni engu-7. Ngemuva kuka-2016, izozinza ku-20GWh ngonyaka.

Ngokombono wesabelo semakethe, isabelo semakethe se-lithium iron phosphate siye sahlala singaphezu kuka-70% kusukela ngo-2010 kuya ku-2014. Nokho, ngemva kuka-2016, ngenxa yokulungiswa kwezinqubomgomo zomxhaso kanye nokuxhumana phakathi kokuqina kwamandla, amabhethri e-lithium iron phosphate aqala ukupholisa. emakethe, ikhula kancane kancane isuka ngaphezu kwama-70% emakethe ngaphambi kuka-2014. Ngo-2019, yehle yaba ngaphansi kuka-15%.

Ngalesi sikhathi, amabhethri e-lithium iron phosphate nawo athole ukungabaza okuningi, futhi ake afana nokubuyela emuva, futhi sekuke kwaba nomkhuba wokushiya i-lithium iron phosphate. Ngemuva kwalolu shintsho futhi kukhombisa ukuthi ngaphambi kuka-2019, imakethe incike kakhulu kunqubomgomo.

Ngokusebenza kobuchwepheshe kanye nezindleko, kungabonisa ukuthuthukiswa nokuvuthwa kwezimboni kobuchwepheshe bebhethri ye-lithium iron phosphate ngokwezinga elithile. Eminyakeni eyi-10 edlule, ukuminyana kwamandla kukhuphuke ngesilinganiso sika-9% ngonyaka, futhi izindleko zehle ngo-17% ngonyaka.

Unjiniyela omkhulu wezobuchwepheshe we-ANCH u-Bai Ke ubikezela ukuthi ngo-2023, ukwanda kwamandla e-lithium iron phosphate kuzokwehla kancane kancane kuye cishe ku-210Wh/kg, futhi izindleko zizokwehla zibe ngu-0.5 yuan/Wh.

I-2020 iyindawo yokuguqula amabhethri e-lithium iron phosphate

Kusukela ngo-2020, ibhethri ye-lithium iron phosphate eyake yathula isiqalile ukukhuphuka futhi ifaka umjikelezo omusha wokukhula.

I-logic ngemuva ikakhulukazi ihlanganisa:

Okokuqala nje, izimoto ezintsha zamandla zimisiwe, futhi imigqa ehlukene yomkhiqizo nobuchwepheshe isiqalile ukuthola amathrekhi azo; okwesibili, esikalini esithile seziteshi eziyisisekelo ze-5 g, imikhumbi, imishini yokwakha nezinye izimakethe, izinzuzo zamabhethri e-lithium iron phosphate zivelele, futhi ezintsha zivuliwe. Amathuba ezimakethe; okwesithathu, ngokukhula kwemakethe yebhethri, ibhizinisi lokuphela kwe-ToC lisekela amaphuzu amasha okukhula, okunikeza izinketho ezintsha zamabhethri e-lithium iron phosphate.

Amamodeli amathathu ezinto ezithintekayo kakhulu asemkhakheni wezimoto zikagesi, i-Tesla Model 3, i-BYD Han Chinese ne-Hongguang miniEV, zonke ezifakwe amabhethri e-lithium iron phosphate, nawo aletha umcabango omkhulu emkhakheni wezimoto zikagesi. Izimoto zinezicelo zazo esikhathini esizayo.

Njengoba imakethe iqala ukusuka kude nezinqubomgomo futhi iqhubekela emakethe yangempela, amathuba amabhethri e-lithium iron phosphate azovuleka.

Ngokombono wedatha yemakethe, umthamo ofakiwe we-lithium iron phosphate yezimoto kulindeleke ukuthi ufinyelele ku-20Gwh ngo-2020. Ngaphezu kwalokho, ukuthunyelwa kwamabhethri e-lithium iron phosphate emakethe yokugcina amandla kulindeleke ukuthi kufinyelele cishe ku-10Gwh.

Ishumi leminyaka elisha lamathuba amabhethri e-lithium iron phosphate

Uma sibhekene no-2021, akungabazeki ukuthi amabhethri e-lithium iron phosphate azovula isikhala esengeziwe ekusetshenzisweni kwemakethe okuhlukahlukene.

Ekufakweni kukagesi okudidiyelwe kohlelo lwamandla, ukuthambekela kokuthuthwa komhlaba kanye nokufakwa kukagesi emotweni akunakuhlehliswa. Ukufakwa kukagesi kwemikhumbi nakho kuyakhula ngesivinini, futhi izindinganiso ezifanele zilokhu zithuthuka; ngesikhathi esifanayo, imakethe yezindiza zikagesi iqala ukuzama. Le mikhiqizo izothatha ingxenye ethile emakethe yebhethri ye-lithium iron phosphate.

Inkambu yokugcina amandla izoba yinkundla yesibili yempi yamabhethri e-lithium iron phosphate. Isitoreji samandla sihlukaniswe ikakhulukazi isitoreji samandla esikhulu esihlanganiswe negridi yamandla kanye nesitoreji samandla esincane esimelwe iziteshi eziyisisekelo ze-5G, ezodlala indima ehamba phambili emakethe yesicelo sebhethri ye-lithium iron phosphate.

Ngaphezu kwalokho, ezimakethe zezicelo ezisafufusa, okuhlanganisa ama-forklift kagesi, ama-mopeds kagesi, isipele sesikhungo sedatha, isipele se-elevator, ukunikezwa kwamandla kagesi wemishini yezokwelapha nezinye izimo, kuzoletha amathuba athile kanye nesikhala samabhethri e-lithium iron phosphate.

Ukuhlukahluka kwezimakethe, ukuthuthukiswa kokuhlukaniswa kwemikhiqizo

Izimakethe ezihlukene ziphinde zabeka izidingo ezihlukene zamabhethri e-lithium, ezinye zidinga impilo yebhethri ende, ezinye zidinga ukuminyana kwamandla aphezulu, kanti ezinye zidinga ukusebenza okubanzi kwezinga lokushisa. Ngisho namabhethri e-lithium iron phosphate adinga ukuthuthukiswa okuhlukene ukuze kuhlangatshezwane nezidingo namaphuzu obuhlungu bezimo ezihlukene zohlelo lokusebenza.

I-ALCI Technology yasungulwa ngoMeyi 2016, futhi ibilokhu ibambelela kumzila we-lithium iron phosphate technology. Ngokuhloswe ngesidingo semakethe esizayo, u-Baike wethule isiqondiso sokuthuthukiswa kobuchwepheshe be-AlCI emkhakheni wamabhethri e-lithium iron phosphate.

Ngokuya ekukhuleni kwabantu bamandla, inkathi yokuphishekela ngamandla ukuminyana kwamandla isidlulile, kodwa njengohlobo lokuthwala amandla, ukuminyana kwamandla kuyinkomba yobuchwepheshe okufanele ibhekane nayo.

Ukuze kuxazululwe le nkinga, i-Anchi ithuthukise i-electrode ewugqinsi ehlelwe ngokwesakhiwo, eqeda ukumelana okuphezulu kwangaphakathi nokukhuphuka kwezinga lokushisa eliphezulu kwebhethri ngokulinganisa i-polarization yepuleti le-electrode. Ingenza ibhethri ye-iron-lithium ibe nempilo ende kanye nokuminyana kwamandla okuphezulu. Isisindo sokuminyana kwamandla samabhethri e-lithium iron asekelwe kulobu buchwepheshe sidlula u-190Wh/Kg, futhi ivolumu idlula u-430Wh/L.

Ukuze kuhlangatshezwane nezidingo zokusetshenziswa kwamabhethri wamandla ezimeni zokushisa eziphansi, i-ANch iphinde yasungula amabhethri e-lithium iron phosphate okushisa aphansi. Ngokusebenzisa inhlanganisela ye-low-viscosity superelectrolyte, inethiwekhi ye-ion/electronic superconducting, i-graphite ye-isotropic, i-ultrafine nanometer lithium iron nobunye ubuchwepheshe, ibhethri lingasebenza ngokujwayelekile endaweni yokushisa ephansi.

Ngaphezu kwalokho, ekuthuthukisweni kwamabhethri empilo ende, ngokusebenzisa i-lithium ephansi yokusetshenziswa kwama-electrode angalungile, ama-electrode amahle okuzinza okuphezulu, kanye nobuchwepheshe bokuzilungisa be-electrolyte, imijikelezo engaphezu kuka-6000 yamabhethri e-lithium iron phosphate iye yazuzwa.
