Tesla yuav siv LiFePO4 hlwb hloov cov hlwb cobalt hauv Suav teb?
Nthuav xov xwm los ntawm Far East. Reuters qhia Tesla yog nyob rau hauv kev sib tham ua ntej nrog LiFePO roj teeb tus neeg muag khoom4 (Lithium Iron Phosphate, LFP). Lawv muab lub zog qis dua li lwm cov cobalt-based lithium-ion hlwb, tab sis kuj tseem pheej yig dua.
Tesla puas yuav txhawb kom lub ntiaj teb siv LFP hlwb?
LFP (LiFePO4) tsis tshua muaj nyob hauv tsheb vim tias lawv tuaj yeem khaws cia tsawg zog rau tib qhov hnyav. Qhov no txhais tau hais tias sim tswj cov roj teeb uas tau xaiv (xws li 100 kWh) yuav tsum tau siv cov roj teeb loj thiab hnyav dua. Thiab qhov no tuaj yeem yog teeb meem thaum lub tsheb tau dhia 2 tons hauv qhov hnyav thiab nce mus txog 2,5 tons ...

Txawm li cas los xij, raws li Reuters, Tesla tab tom tham nrog CATL los muab LiFePO hlwb.4... Lawv yuav tsum pheej yig dua "los ntawm ob peb kaum feem pua" dua li "tiag tiag". Nws tsis tau nthuav tawm seb NCA hlwb uas Tesla siv thoob ntiaj teb tau raug suav tias yog "tam sim no," lossis NCM qhov txawv nws xav tau (thiab siv?) Hauv Suav teb.
NCA yog nickel-cobalt-aluminium cathode hlwb thiab NCM yog nickel-cobalt-manganese cathode hlwb.
LiFePO Cell4 lawv muaj cov kev tsis zoo no, tab sis lawv kuj muaj ntau qhov zoo: lawv cov kab tawm tawm yog kab rov tav ntau dua (tsawg kawg qhov hluav taws xob poob thaum lub sijhawm ua haujlwm), lawv tiv taus ntau lub voj voog tawm thiab muaj kev nyab xeeb dua li lwm cov lithium-ion hlwb. Nws tseem yog ib qho nyuaj rau overestimate qhov tseeb tias lawv tsis siv cobalt, uas yog ib qho khoom kim heev thiab tsis tu ncua ua rau muaj kev sib cav vim qhov chaw ntawm nws cov deposits thiab cov me nyuam uas accustomed mus ua hauj lwm nyob rau hauv mines.
