LG Energy Solution rov qab mus rau LiFePO4 hlwb. Thiab qhov zoo, peb xav tau lawv rau pheej yig hluav taws xob tsheb.
Txog tam sim no, LG Zog Kev daws teeb meem (yav tas los: LG Chem) tau tsom feem ntau ntawm cov lithium-ion hlwb nrog nickel-cobalt-manganese thiab nickel-cobalt aluminium (NCM, NCA) cathodes. Lawv muaj peev xwm loj, tab sis kim vim yog cobalt lawv siv. Lithium Hlau Phosphate Cells (LiFePO4, LFP) muaj lub zog qis dua, tab sis pheej yig dua.
LG npaj siab tawm tsam CATL thiab BYD
Niaj hnub no, cov tuam txhab loj tshaj plaws ntawm LFP hlwb thiab, tib lub sijhawm, cov tuam txhab lag luam nqis peev feem ntau hauv lawv txoj kev loj hlob yog Tuam Tshoj CATL thiab Tuam Tshoj BYD. Ob lub tuam txhab txhawb nqa lawv li kev nyab xeeb thiab pheej yig cov kev daws teeb meem, txawm hais tias muaj lub zog tsawg. Yuav luag tag nrho lub ntiaj teb tsheb tsheb (tshwj tsis yog Tuam Tshoj) tau pom kev txaus siab rau lawv kom txog thaum Tesla ua rau txhua tus xav tsis thoob los ntawm kev siv lawv hauv Model 3 SR +.
Tam sim no cov chaw tsim khoom thov qhia tias LFP hlwb ncav cuag lub zog ceev ntawm 0,2 kWh / kg, uas yog sib npaug nrog NCA / NCM hlwb tsuas yog 4-5 xyoo dhau los. Hauv lwm lo lus: muaj "txaus" ntawm lawv txawm nyob hauv kev lag luam tsheb. LG tsis kam siv cov thev naus laus zis no, ntseeg tias nws yog band limiting., thiab lub tuam txhab insisted rau qhov loj tshaj qhov deb ntawm cov roj teeb. Kev tshawb fawb LFP tsis tau ua tiav rau ze li 10 xyoo, tab sis tam sim no nws yog lub sijhawm rov qab los rau nws. Ntxiv mus, lithium-hlau-phosphate hlwb tsis muaj cobalt (keeb) lossis npib tsib xee ( pheej yig dua, tab sis kuj tseem kim), yog li cov khoom kim heev yog lithium.

LFP cov kab ntau lawm yuav tsim los ntawm Daejeon cog hauv Kaus Lim Qab Teb thiab yuav tsis ua haujlwm txog xyoo 2022. Cov khoom siv raw yuav muab los ntawm Suav koom tes ua lag luam. Raws li The Elec, LG npaj yuav tso nws tus kheej LFP hlwb raws li tsim nyog rau cov nqi qis tsheb uas tus nqi qis yog qhov tseem ceeb. Lawv kuj yuav tsum tau siv rau hauv cov lag luam tawm tshiab.
Editor's note www.elektrowoz.pl: Kuv xav tias nws nyuaj rau tau txais xov xwm zoo dua hnub no. LFP hlwb raug ntes mus rau NCA / NCM / NCMA hlwb thaum pheej yig dua thiab ruaj khov dua. Lub zog tiag tiag ntawm Opel Corsa-e yog kwv yees li 280 mais. Yog tias nws siv LFP hlwb, lub tsheb yuav xav tau hloov lub roj teeb nrog mileage tsawg kawg yog 1 (!) kilometers - vim lithium-hlau-phosphate chemistry tiv taus ntau txhiab lub voj voog ua haujlwm.
Qhov no yuav txaus siab rau koj:
