I-CATL Yethula Ibhethri Elihlanganisiwe: Ingabe i-Ternary ne-LFP Ziyashintsha Zisuka Ekuncintiseni Ziye Ekuhlanganiseni?

NgoJanuwari 22, i-CATL yethule i-"Tianxing II Light Commercial All-Scenario Customized Series Solutions" kanye nesicelo sayo esihlakaniphile esisekelayo esithi "Battery Butler" Tianxing Edition. Okubaluleke kakhulu phakathi kwalokhu yi-Tianxing II Light Commercial Long-Range Battery, ehlome ngeseli yokuqala yokuhlanganisa amakhemikhali amaningi (ultra-hybrid) yezimoto ezincane. Lo mkhiqizo uhlanganisa izinto zethinari lithium ne-lithium iron phosphate ngaphakathi kohlelo olufanayo lwamakhemikhali.

Engqungqutheleni yabezindaba, i-Chief Technology Officer ye-CATL, uGao Huan, uchaze kabanzi ngempumelelo yale teknoloji: "Ngaphakathi, sibiza lolu hlelo lwezinto zethinari-lithium-iron-phosphate uhlelo oluhlanganisiwe (ultra-hybrid system). Luhilela ukuxuba izinto zebhethri, umphumela oqondile kakhulu ukwanda kwamandla eseli ngenkathi kulawulwa izindleko."

Eqinisweni, izinyanga ezintathu ngaphambili, i-CATL yayihlangene yakhipha ibhethri lesistimu ye-ultra-hybrid ne-Leapmotor futhi yamemezela ukuthi izofakwa kumodeli ye-Leapmotor enkulu, i-D19.

UGao Huan uthe: "Njengamanje, i-volumetric energy density ephezulu kakhulu yezinto ze-lithium iron phosphate ezikhiqizwa ngobuningi ingafinyelela ku-450 watt-hours ilitha, kanti izinto ze-ternary ziqala ku-500 watt-hours ilitha." Lapho amamodeli athile ezimoto edinga amabhethri anama-energy densities phakathi kuka-480 no-500 watt-hours ilitha, i-lithium iron phosphate yakudala ayikwazi ukuhlangabezana nesidingo, kanti izinto ze-ternary zizokhuphula kakhulu izindleko.

Ukuvela kwebhethri ye-ultra-hybrid kuhlose ukugcwalisa leli gcoyana. Akugcini nje ngokudlula isilinganiso se-energy density ye-lithium iron phosphate kodwa futhi kugwema izindleko eziphezulu ezihambisana ne-pure ternary lithium.

Namuhla, imakethe yezimoto ezintsha zamandla inezidingo eziphakeme kakhulu zokushayela ibanga. Ngo-2025, ezinye izimoto ezinezinhlobo ezandisiwe zazivele zihlome ngebhethri elingaphezu kuka-60 kWh, futhi ngo-2026, amamodeli amaningi, okubalwa kuwo uchungechunge lwe-Leapmotor's D, kulindeleke ukuthi zibe namandla ebhethri acishe abe ngu-80 kWh.

Ukuze amabhethri e-lithium iron phosphate afinyelele ibanga eligcwele lombane elingaphezu kwamakhilomitha angu-500, amanye amangqamuzana avame ukudingeka ukuthi afakwe phezulu, okungase kuholele ekutheni isisindo sezimoto sibe ngaphezu kwamathani amathathu, okuthinta ukulawulwa nokuphepha. Ngenkathi amabhethri e-lithium ternary angakwazi ukuhlinzeka ngamandla aphezulu, izindleko zihlala ziyisithiyo esikhulu ekwamukelweni kwawo emakethe ejwayelekile.

Amabhethri e-solid-state abhekwa njengesikhombisa sobuchwepheshe bamabhethri esizukulwane esilandelayo. Ngokwezibikezeli zika-Academician Ouyang Minggao we-Chinese Academy of Sciences, ukusetshenziswa kwamabhethri e-all-solid-state kungase kuqale phakathi kuka-2027 no-2028, ngokukhiqizwa ngobuningi okukhulu kulindeleke ngo-2030. Kodwa-ke, amabhethri e-solid-state aseneminyaka embalwa ukusuka ekuthengisweni ngobuningi, futhi izinto zawo ze-cathode zisasekelwe kakhulu ezinhlelweni eziphakeme ze-nickel ternary. Lokhu kudala isikhala sokuthuthukisa ubuchwepheshe obudlulayo njenge-ultra-hybrid battery.

Ukuqaliswa kobuchwepheshe kwebhethri ye-ultra-hybrid akuyona nje ukuxubana kwezinto ezimbili. U-Gao Huan uvumile emhlanganweni: "Kunezinkinga eziningi zobuchwepheshe okufanele zinqotshwe, okubandakanya izinkinga zesixhumanisi phakathi kwe-ternary ne-lithium iron phosphate, izinkinga zenkundla yamandla kagesi, kanye nezinkinga zokunciphisa nokukhuphula i-electrolyte, phakathi kwezinye."

Lokhu kuhlanganiswa ezingeni lezinto kwengeza umqondo "webhethri ye-dual-core" kaCATL wangaphambili ezingeni lesakhiwo sesistimu. E-Super Technology Day ngo-Ephreli 2025, iCATL yethula iXiaoyao Dual-Core Battery, ezuza ukugcwalisana kokusebenza ngokuhlela amabhethri anezinhlelo ezihlukahlukene zamakhemikhali ezindaweni ezihlukene. Ngokwesibonelo, ukuhlanganiswa kwe-sodium-ion ne-lithium iron phosphate kungaqondisa izindawo ezibandayo kakhulu ezindaweni ezisenyakatho, kanti ukuhlanganiswa kwe-ternary lithium ne-lithium iron phosphate kulinganisa ukusebenza okuphezulu nebanga elide.

Kusukela ekwakhiweni kohlelo lwe-"dual-core" kuya ezingeni lezinto ze-"ultra-hybrid", i-CATL yenza imingcele yokusebenza yamabhethri amandla ajwayelekile ngobukhulu obuningi. Uphrofesa u-Ai Xinping waseNyuvesi yaseWuhan uthe: "I-Ternary lithium ne-lithium iron phosphate akuyona ubudlelwano obuphikisanayo obuthi 'noma-noma' kodwa ukukhetha okusekelwe ezimweni okusekelwe ezicini ezihlukene zobuchwepheshe." Lo mbono uhambisana necebo lobuchwepheshe le-CATL.

Esithangwini, uGao Huan uveze isikhathi esibalulekile: ukukhiqizwa ngobuningi kwezohwebo kwebhethri ye-ultra-hybrid ye-CATL kulindeleke ukuthi iqale ngo-Ephreli 2026. Lokhu kusho ukuthi kusele izinyanga ezingaphansi kwezintathu ngaphambi kokuthi leli thuluzi lingene emakethe ngokusemthethweni.

Ukukhetha kwe-CATL ukwethula umkhiqizo webhethri ye-ultra-hybrid kuqala emkhakheni wezimoto zokuhweba kunengqondo yezohwebo. U-Gao Huan wachaza: "Ezikhathini zokulethwa phakathi kwamadolobha, ibanga lokushayela elidingekayo liyanda. Ukusebenzisa izinto zokwakha kuphela kungenza kube nzima ukulungisa izindleko. Ngaphezu kwalokho, ukushaja kusenzima ukuba lula, ngakho-ke sisebenzise ngobuhlakani ibhethri yesistimu ye-ultra-hybrid emkhakheni wezimoto zokuhweba."

Kuyaziwa ukuthi ibhethri i-Tianxing II Light Commercial Long-Range Battery inamandla angu-253 kWh, okuyinto enkulu kunazo zonke embonini yezimoto ezincane zokuhweba. Ifakwe leli bhetri, izimoto zingafinyelela ibanga langempela elingamakhilomitha angu-800, kalula nje zihlanganisa imizila ejwayelekile phakathi kwamadolobha njengeGuangzhou kuya eFuzhou ngaphandle kwesidingo sokushaja phakathi nohambo. Ngaphezu kwalokho, iwaranti yebhethri yelulwe yaba iminyaka eyi-10 noma amakhilomitha ayisigidi, futhi ubuchwepheshe obufana nezinto zokukhokha i-lithium ezizihlelayo kanye ne-electrolyte ezizilungisayo zisetshenziswa ukuze kunwetshwe impilo yebhethri. Lezi zici zilungele kakhulu izimo zokusebenza zezimoto zokuhweba ezidinga umnotho ophakeme nokwethembeka.

Mayelana nokuncintisana emakethe nesivinini sokukhiqizwa ngobuningi komkhiqizo, uGao Huan uthe: "Ezinye izinkampani nazo ziyayihlola amabhethri e-ultra-hybrid, kodwa i-CATL ingeyokuqala kule ndawo ukuthola impumelelo ekukhiqizeni ngobuningi."

Ngokukhiqizwa kakhulu kwamabhethri e-ultra-hybrid, izinto ze-ternary lithium ne-lithium iron phosphate aziseyona inketho eyodwa kodwa zingasebenza ngokubambisana ngaphakathi kwe-cell efanayo, zisebenzisa izinzuzo zazo. Ngokubuka okubanzi, ubuchwepheshe bamabhethri e-ultra-hybrid bunikeza isiqondiso esisha sokuthuthukiswa embonini yamabhethri amandla.

Njengoba usuku oluqondiswe ekukhiqizweni kakhulu luka-Ephreli 2026 lusondela, amabhethri e-ultra-hybrid azohlolwa ezindaweni zangempela zokuhweba. Ukusebenza kwawo emakethe kuzoncika ezintweni ezahlukahlukene, okubandakanya ukusebenza kwangempela, amakhono okulawula izindleko, nokunye.
