LG Chem: 811, 622 -> 712

LG Chem e se e ntse e hlahisa lisele tse nang le cathode ea NCM 811 (Nickel-Cobalt-Manganese | 80% -10% -10%), empa tsena li sebelisoa feela libese. Moloko oa boraro oa lisele tse nang le lihlahisoa tse phahameng tsa nickel le lihlahisoa tse tlaase tsa cobalt li lebelletsoe ho fana ka matla a phahameng a polokelo ea matla. Ho phaella moo, cathode e tla kenngoa ka graphite, e tla potlakisa ho tjhaja.

Theknoloji ea NCM 811 e sebelisoa liseleng tsa cylindrical., ha ka mokotleng re ntse re le theknoloji NCM 622 - 'me likarolo tsena li teng likoloing tsa motlakase... Nakong e tlang, aluminium e tla kenngoa ka mokotleng 'me likarolo tsa tšepe li tla fetoloa ho NCMA 712. Lisele tsa mofuta ona tse nang le karolo e ka tlaase ho 10 lekholong ea cobalt li tla hlahisoa ho tloha 2020.

Ka kakaretso: ho fokotseha ha cobalt, ho theola tlhahiso ea lisele. Ka hona, lisebelisoa tse tala bakeng sa betri e nang le lisele tsa NCM 811 li lokela ho theko e tlaase ho feta lisebelisoa tse tala bakeng sa betri e sebelisang NCM 622. Leha ho le joalo, lisele tsa 622 li ka fana ka matla a phahameng bakeng sa boima bo tšoanang, empa li theko e boima haholo.

Ka lebaka la theko e ntseng e hola ka potlako ea cobalt mebarakeng ea lefats'e, bahlahisi ba lebile ho 622 -> (712) -> 811.

Tlhokomeliso: bahlahisi ba bang ba sebelisa letšoao la NCM, ba bang NMC.

Ka holimo: SK Innovation NCM 811 sachet e nang le li-electrode tse bonahalang mahlakoreng ka bobeli.
