Tesla atha kukhala wopanga magalimoto woyamba kugwiritsa ntchito ma cell a LG NCMA.

Nthambi ya ku Poland ya LG Energy Solution (LGES, LG En Sol) idadzitamandira kuti mu theka lachiwiri la chaka kampaniyo idzayamba kutumiza maselo atsopano ndi [Li-]NCMA cathodes, ndiko kuti, nickel-cobalt-manganese-aluminium cathodes. Pakadali pano, Business Korea yaphunzira kuti Tesla atha kukhala wolandila woyamba.

LG Energy Solution ndi zinthu za Tesla

Zamkatimu

• LG Energy Solution ndi zinthu za Tesla
  • Maselo atsopano ndi Model Y

Tesla wakhala akugwiritsa ntchito ma cell okhala ndi ma cathodes a NCA (nickel-cobalt-aluminium) opangidwa ndi kampani yaku Japan Panasonic kwa zaka zambiri. Akalowa mumsika waku China, wopanga adasaina mapangano owonjezera ndi LG Energy Solution (ndiye: LG Chem) ndi CATL kuti apereke. ena maselo. Patapita nthawi, zinapezeka kuti pa CATL, awa ndi maselo a LiFePO.₄ (lithium-iron-phosphate), ndipo ku LG, wopanga California adzalandira zinthu za [Li-] NCM (nickel-cobalt-manganese).

Tsopano Business Korea ikulengeza kuti wopanga waku South Korea ayamba kupereka Tesla ndi ma cell atsopano okhala ndi ma cathode a NCMA koyambirira kwa Julayi 2021. Ichi chidzakhala ntchito yawo yoyamba yamalonda. Maselo a NCMA ndi zinthu zomwe zili ndi nickel yochuluka (90 peresenti), cobalt yamtengo wapatali ndi 5 peresenti yokha, ndipo aluminium ndi manganese amachita zina. Anode awo amapangidwa ndi kaboni, koma monga tikudziwira kuchokera kuzinthu zina, amapangidwa ndi silicon kuti awonjezere mphamvu ya batri.

Maselo atsopanowa amayenera kuwonekera koyamba mu mabatire a General Motors Ultium, komanso makamaka mu Hummer EV. Komabe, zikuwoneka kuti zidzawonekera koyamba mu Tesla Model Y. NCMA cathodes idzagwiritsidwa ntchito m'maselo a cylindrical a Tesla, ndipo pambuyo pake adzawonekeranso m'maselo a sachet, omwe LGES amapanga, pakati pa ena. pafupi ndi Wroclaw. Chotsatiracho chidzakhala chocheperapo - 85 peresenti ya nickel.

Maselo atsopano ndi Model Y

Khomo la Electrek likuwonetsa kuti ma cell apita kumagalimoto opangidwa ku fakitale ya Tesla ku Shanghai, China, kutanthauza kuti azikhala mumtundu wakale wa 2170 (21700). Koma ndi bwino kukumbukira kuti mu theka lachiwiri la chaka, oyendetsa ndege a Tesla Model Y ku Grünheide (Giga Berlin, Germany) ayenera kuyamba, momwe maselo a 4680 adzawonekera. chemistry. ndi mawonekedwe atsopano, kapena adzalandira ma cathodes atsopano.

Izi zaposachedwa zikakhala zoona, mitundu ya Y yopangidwa pafupi ndi Berlin idzakhala yopepuka kuposa mitundu yaku America (chifukwa mawonekedwe a NCMA ndi 4680 amalola kuchulukitsitsa kwamphamvu kwapapakuti), kapena padzakhala zosinthika zokhala ndi batire yochulukirapo kuposa kale. (chifukwa mawonekedwe 4680 ali ndi mphamvu zambiri pa paketi yofanana).

Chithunzi choyambirira: Ma cell 21700 LGES okhala ndi chemistry ya NCM811 opangidwira Lucid Motors (c) Lucid Motors
