Elon Musk: Kwayoyin mu (= Tesla) sun kasance a cikin motoci na watanni da yawa. Silicon anodes ?! 4680 ku!

Elon Musk ya yi tweeted jimloli uku waɗanda ke bayyana saƙon Ranar Baturi a sarari. A yayin taron, shugaban na Tesla ya sanar kuma ya yi alkawari, yayin da, kamar yadda ya faru, "Tesla cell [4680] a cikin fakitin sun kasance a cikin motoci na watanni da yawa." Amma wannan magana wani bangare ne na ma fi girma da ban sha'awa gabaki ɗaya.

Abubuwan da ke ciki

• Kwayoyin 4680 sun riga sun kasance cikin samfura, za su kasance a cikin Tesla Model Y daga Berlin, mai yiwuwa NMC daga LG Chem
  • Babban ajiyar makamashi daga LFP, ƙarami da motoci daga NM, manyan motoci daga hN
  • Labarai # 1: Shin sel NCA an ware su a hankali, gami da Panasonic?

Bari mu fara da Twitter. Tattaunawar da ake yi dole ne a fassara ta sosai sannan a sanya ta cikin mahallin domin fahimtar ma'anarta. To ga shi (source):

Gaba dayan kasida na Mars: Elon, kuna yin sel 4680 tare da cathodes daban-daban guda uku [graphite, silicon da nickel]? Ko, lokacin da kuke magana game da tsarin kula da daraja, kuna magana ne game da fitar da kayayyaki?

Elon Musk: Masu kaya. Muna fama da nickel mai ƙarfi kawai, aƙalla a yanzu. Har ila yau, mai yiwuwa ba a bayyana ba daga gabatarwar cewa a zahiri muna da kejin mu a cikin fakitin motocin tuki na wasu watanni. Samfuran ba su da mahimmanci, samar da taro yana da wahala.

Babban ajiyar makamashi daga LFP, ƙarami da motoci daga NM, manyan motoci daga hN

Tattaunawar ta ta'allaka ne a kan faifai inda nau'ikan cathodes daban-daban suka dace da buƙatu daban-daban. Hagu:

• Kwayoyin LFP, tare da lithium iron phosphate cathodes (babu cobalt) je zuwa wuraren da farashin farashi, watau Tesla Model 3 SR + (da sauransu), sabon Tesla, na'urorin ajiyar makamashi,

Mu karanta wannan bayanin a hankali:

Labarai # 1: Shin sel NCA an ware su a hankali, gami da Panasonic?

Har zuwa yanzu, Tesla ya yi amfani da ƙwayoyin lithium-ion tare da NCA cathodes, [lithium] nickel-cobalt-aluminum. An ɗan canza tsarin a China, inda ƙwayoyin NCM da LFP suka bayyana, amma a cikin Masarautar Tsakiyar ya yi kama da gwaji na farko kawai. Bugu da ƙari, kwanan nan Panasonic ya yi alfahari cewa yana inganta ƙwayoyin NCA, kuma an shirya shi don kawar da cobalt kawai a cikin 'yan shekaru.

A halin yanzu, gabatarwar ya nuna cewa makomar kwayoyin NCA suna cikin tambaya. Babu shakka ba a gefen hagu suke ba. Suna iya zama daidai, amma Tesla ya taka rawa. A ciki, ƙwayoyin NCM ne ke raba su.

Tambayar budewa: ta yaya haɗin gwiwar Tesla da Panasonic ke tafiya?

Wasiƙar #2: Menene waɗannan tweets na "Masu bayarwa" ke nufi?

Kamar yadda Elon Musk ya bayyana, Tesla yayi hulɗa da gefen dama na gabatarwa, kuma ya bar sauran biyun ga masu ba da kaya. Ana gani daga hagu, har ma kuna iya faɗin sunayen: CATL / CATL da LG Chem / Tesla (da Panasonic?).

Wannan ilimin zai yi mana amfani a labarai # 4.

Labarai Na 3: sel 4680 a cikin sabbin fakiti sun riga sun fara motsi

Kwayoyin Tesla a cikin fakiti suna kan hanyarsu. Abubuwan mu na iya ƙunshi sel 4680 da kuma manyan ƙwayoyin nickel tare da anodes na silicon. Kuma tabbas duka biyun, saboda samfurin Tesle Semi da aƙalla Cybertruck ɗaya sun riga sun yi aiki. Wato, an gwada su don juriya ga damuwa, raguwa a lokacin caji, da dai sauransu.

Abun labarai # 4: Tsarin Tesla na Turai zai sami sel 4680

A yayin zaman Q&A, Elon Musk ya sanar da cewa "za su samar da sel a Berlin." Sanarwa watakila Dangane da samarwa gaba ɗaya, shuka zai samar da abubuwan, amma Panasonic bai riga ya yi alfahari da cewa yana buɗe layinsa a can ba (waɗanda ke Nevada mallakar Jafananci ne).

Yana kama sabili da haka, gaskiyar cewa "za mu samar da kwayoyin halitta a Berlin" ya kamata a fahimta sosai: "Tesla zai gina nasa sel a Berlin ".

Kuma tun da Tesla nan da nan yana saurare zuwa hanyoyin haɗin gwiwar 4680, tun da yake suna samar da ƙarfin tsarin, waɗanda daga Berlin za su bi ta cikin teku zuwa Cybertruck da Tesla Semi, ko kuma. Tsarin Tesla na Turai zai sami sel 4680.

Wannan na ƙarshe yana da ma'ana, amma tsakiyar ɓangaren Tesla Model Y slide shine ƙwayoyin nickel-manganese (NM), ba ƙwayoyin nickel masu girma ba. A halin yanzu, maganganun sun nuna cewa Tesla a halin yanzu yana mai da hankali kan ƙwayoyin nickel masu girma (aiki mun sanya su a matsayin "hN"). Don haka, mun yanke hukunci kamar haka:

• la'akari da cewa za a sami masana'antar batir a Giga Berlin, muna sa ran hakan Model Y na Tesla ba dade ko ba dade zai karɓi baturin tsari bisa sel 4680.don komai ya kasance a wurin,
• Tun da Tesla Model Y zai sami batirin tsarin sel 4680 kuma Tesla yana mai da hankali kan ƙwayoyin nickel masu girma, wannan yana nufin cewa sauran masu ba da kaya (LG Chem!) Za su kera sel 4680 tare da cathodes nickel-manganese..
