Mabatire atsopano otsika mtengo a Tesla chifukwa cha mgwirizano ndi CATL kwa nthawi yoyamba ku China. Pansi pa $ 80 pa kWh pamlingo wa phukusi?
Uthenga wodabwitsa wa Reuters. Tesla, mogwirizana ndi CATL, akukonzekera kuyambitsa batire yatsopano yotsika mtengo yochokera ku maselo osinthidwa a lithiamu-ion ku China. Imatchedwa "batire ya mailosi miliyoni [makilomita 1,6 miliyoni]" koma zambiri sizili momwe zilili.
Maselo atsopano a Tesla = LiFePO4? Mtengo wa NMC532
Malinga ndi a Reuters, "batire yama miliyoni miliyoni" idzakhala yotsika mtengo ndipo iyenera kukhala nthawi yayitali. Poyamba, maselo amayenera kupangidwa ndi CATL ya China, koma Tesla akufuna kupanga teknoloji kuti athe pang'onopang'ono - chifukwa cha kutulutsa kwina - kuyamba kupanga.
Reuters sapereka zambiri za ma cell, kotero titha kungolingalira za kapangidwe kawo. Izi zitha kukhala ma cell a lithiamu iron phosphate (LFP, LiFePO4), zomwe zimagwirizana ndi ziganizo zonse ziwiri ("zotsika mtengo", "zamoyo wautali"). Itha kukhalanso mtundu wina wa maselo a lithiamu-ion okhala ndi cathodes NMC 532 (nickel-manganese-cobalt) kuchokera ku kristalo imodzi:
> Tesla akufunsira patent yama cell atsopano a NMC. Mamiliyoni a kilomita amayendetsedwa ndikuwonongeka kochepa
Zotsirizirazi sizingakhale "zotsika mtengo" chifukwa cha cobalt zomwe zili mu cathode (peresenti ya 20), koma ndani akudziwa ngati Tesla adaphimba zonse zomwe zili patent? Mwina mtundu wa NMC 721 kapena 811 wayesedwa kale? … Wopanga amadzitamandira kuti amatha kukwaniritsa zozungulira 4.
Ndipo njira imodzi yomaliza: ndizotheka kuti ma cell a CATL awa ndi mtundu wowongoka wa omwe ali ndi ma cathodes a NCA (Nickel-Cobalt-Aluminium), omwe, kuyambira 2018, ali ndi cobalt yochepera 3 peresenti.
"Magwero" omwe atchulidwa ndi bungweli akuti Mtengo wapatali wa magawo LiFePO4 zopangidwa ndi CATL - zosakwana madola 60 pa 1 kWh. Ndi batire yonseyo, ndiyochepera $80 pa ola la kilowatt. Kwa ma cell a cobalt a NMC otsika, mtengo wa batri uli pafupi $100/kWh.
Malinga ndi Reuters, mtengo wopangira ma cell osamvetsetseka ndi otsika kwambiri kotero kuti magalimoto oyendetsedwa ndi iwo amatha kufanana ndi mtengo wa magalimoto oyaka mkati (gwero). Koma kachiwiri, chinsinsi: kodi tikulankhula za kutsika kwamitengo ya Teslas yomwe ikugulitsidwa pano? Kapena mwina wopanga osadziwika? Zimangodziwika kuti ma cell adzayamba kupita ku China, ndipo pang'onopang'ono akhoza kuwonetsedwa kumisika ina mu "magalimoto owonjezera a Tesla.".
Titha kumva zambiri za izi pa Tsiku la Battery, lomwe liyenera kuchitika mu theka lachiwiri la Meyi.
> Tsiku la Battery la Tesla "likhoza kukhala pakati pa Meyi." Mwina…
Chithunzi choyambira: Paketi ya batri ya Tesla Model S (c) yolembedwa ndi Ted Dillard. Maulumikizidwe atsopano sangakhale a cylindrical, amathanso kukonzedwa m'njira zosiyanasiyana.
Izi zingakusangalatseni:
