Tesla e tla sebelisa lisele tsa LiFePO4 sebakeng sa lisele tse thehiloeng ho cobalt Chaena?
Litaba tse monate tse tsoang Bochabela bo Hōle. Reuters e re Tesla e Lipuisanong tsa pele le Battery Supplier LiFePO4 (Lithium Iron Phosphate, LFP). Li fana ka matla a fokolang a matla ho feta lisele tse ling tsa lithium-ion tse thehiloeng ho cobalt, empa hape li theko e tlaase haholo.
Na Tesla e tla kholisa lefatše ho sebelisa lisele tsa LFP?
Tlhaloso ea LFP (LiFePO4) ke ka seoelo ba kenang likoloing hobane ba khona ho boloka matla a fokolang bakeng sa boima bo lekanang. Sena se bolela hore ho leka ho boloka matla a betri a khethiloeng (mohlala 100 kWh) ho hloka ts'ebeliso ea lipakete tse kholoanyane le tse boima tsa betri. 'Me sena e ka ba bothata ha koloi e tlotse boima ba lithane tse 2' me e atamela lithane tse 2,5 ...

Leha ho le joalo, ho latela Reuters, Tesla o ntse a buisana le CATL ho fana ka lisele tsa LiFePO.4... Li lokela ho ba theko e tlaase "ka mashome a 'maloa a peresente" ho feta "ea sebele". Ha e e-s'o senoloe hore na lisele tsa NCA tseo Tesla a li sebelisang lefatšeng ka bophara li ne li nkoa e le "tse teng," kapa mofuta oa NCM oo o o batlang ('me o o sebelisa?) Chaena.
NCA ke lisele tsa cathode tsa nickel-cobalt-aluminium 'me NCM ke lisele tsa cathode tsa nickel-cobalt-manganese.
Lisele tsa LiFePO4 ba na le mefokolo ena, empa ba boetse ba na le melemo e 'maloa: sekhahla sa bona sa ho lahla se na le sephara haholo (ho theoha ho fokolang ha motlakase nakong ea ts'ebetso), ba mamella lipotoloho tse ngata tsa ho ntša tefiso' me ba bolokehile ho feta lisele tse ling tsa lithium-ion. Hape ho thata ho feteletsa taba ea hore ha ba sebelise cobalt, e leng ntho e theko e boima 'me e lula e baka likhang ka lebaka la sebaka sa li-deposit tsa eona le bana ba tloaetseng ho sebetsa merafong.
