LG Energy Solution imabwerera ku maselo a LiFePO4. Ndipo ndizabwino, timawafuna pamagalimoto otsika mtengo amagetsi.
Pakalipano, LG Energy Solution (yomwe kale inali: LG Chem) yakhala ikuyang'ana kwambiri maselo a lithiamu-ion okhala ndi nickel-cobalt-manganese ndi nickel-cobalt aluminium (NCM, NCA) cathodes. Ali ndi mphamvu zambiri, koma ndi okwera mtengo chifukwa cha cobalt omwe amagwiritsa ntchito. Maselo a Lithium Iron Phosphate (LiFePO4, LFP) ali ndi mphamvu zochepa, koma ndizotsika mtengo.
LG ikufuna kulimbana ndi CATL ndi BYD
Masiku ano, opanga zazikulu kwambiri zama cell a LFP ndipo, nthawi yomweyo, makampani omwe amaika ndalama zambiri pakukula kwawo ndi CATL yaku China ndi BYD yaku China. Makampani onsewa adawalimbikitsa ngati njira zotetezeka komanso zotsika mtengo, ngakhale zokhala ndi mphamvu zochepa. Pafupifupi dziko lonse lamagalimoto (kupatula China) lidawonetsa chidwi mwa iwo mpaka Tesla adadabwitsa aliyense powagwiritsa ntchito mu Model 3 SR +.
Zomwe opanga pano akuwonetsa zikuwonetsa kuti ma cell a LFP amafikira mphamvu ya 0,2 kWh / kg, yomwe inali yofanana ndi ma cell a NCA / NCM zaka 4-5 zapitazo. Mwa kuyankhula kwina: pali "zokwanira" za iwo ngakhale mumsika wamagalimoto. LG sanafune kugwiritsa ntchito ukadaulo uwu, poganiza kuti inali kuchepetsa bandi., ndipo kampaniyo idaumirira patali kwambiri pakati pa mabatire. Kafukufuku wa LFP sanachitidwe kwa zaka pafupifupi 10, koma tsopano ndi nthawi yoti mubwererenso. Komanso, maselo a lithiamu-iron-phosphate alibe cobalt (yokwera mtengo) kapena faifi (yotsika mtengo, komanso yokwera mtengo), kotero chinthu chokhacho chomwe chingakhale chokwera mtengo ndi lithiamu.
Fakitale ya batri LG Energy Solution ku Biskupice Podgórna pafupi ndi Wroclaw (c) LGEnSol
Mzere wopanga LFP udzamangidwa pafakitale ya Daejeon ku South Korea ndipo sudzagwira ntchito mpaka 2022. Zopangira zitha kuperekedwa ndi ma China ogwirizana. Malinga ndi The Elec, LG ikukonzekera kuyika ma cell awo a LFP ngati oyenera pamagalimoto otsika mtengo pomwe mtengo wotsika ndi wofunikira. Akuyembekezekanso kugwiritsidwa ntchito m'misika yomwe ikubwera.
Zolemba mkonzi www.elektrowoz.pl: Ndikuganiza kuti ndizovuta kupeza nkhani zabwinoko lero. Maselo a LFP akugwira ma cell a NCA / NCM / NCMA pomwe akukhala otsika mtengo komanso olimba. Mphamvu yeniyeni ya Opel Corsa-e ndi pafupifupi makilomita 280. Ngati itagwiritsa ntchito ma cell a LFP, galimotoyo ingafune kusintha batire mtunda wa pafupifupi 1 (!) makilomita - chifukwa chemistry ya lithiamu-iron-phosphate imapirira masauzande ambiri ogwiritsira ntchito.
