Tesla yana neman takardar haƙƙin mallaka don sabbin ƙwayoyin NMC. Miliyoyin kilomita ana tafiyar da su da ƙarancin lalacewa
Tesla Kanada ya nemi sababbin sel tare da NMC (Nickel-Manganese-Cobalt) cathodes. Ga alama waɗannan abubuwa iri ɗaya ne da dakin binciken Jeff Dunn ya kera don masana'anta, wanda ke ba shi damar yin tafiya miliyoyi na kilomita tare da ƙarancin lalacewa.
Tesla zai tashi daga NCA zuwa NMC?
Tesla a halin yanzu yana amfani da ƙwayoyin lithium-ion tare da NCA cathodes, watau nickel-cobalt-aluminum, tare da kasa da 10 bisa dari cobalt abun ciki, a kalla a cikin Tesla Model 3. Wannan sabon abu a kanta, saboda a cikin mafi kyawun zamani NMC811 Kwayoyin 10% cobalt cathodes. Ana amfani da su - amma suna shiga sabis a hankali, suna maye gurbin abubuwan NMC622.

Kamar yadda Elon Musk ya yi alkawari, Tesla na zamani dole ne yayi tafiya daga kilomita 0,48 zuwa 0,8 miliyan akan baturi. Duk da haka, a nan gaba kadan, zai so ya yi tafiyar kilomita miliyan 1,6 akan wutar lantarki - wannan shine abin da jiki da wutar lantarki na Tesla Model 3 ya kamata su goyi bayan.
Kuma a nan yana taimaka masa ta hanyar nasarorin dakin gwaje-gwaje na Jeff Dunn, wanda ya yi aiki ga Tesla na ɗan lokaci kuma wanda a cikin Satumba 2019 ya ba da cikakken sabon tsarin sinadarai na sel na lithium-ion sel tare da NMC532 cathodes.
Saboda amfani da "kristal guda" cathode da electrolyte tare da a halin yanzu amfani Additives wadãtar da dioxazolones da nitriles na ester na sulfite, dangane da abun da ke ciki na electrolyte (source), shi ne zai yiwu a cimma wadannan:
- rage jinkirin lalata tantanin halitta saboda hana haɓakar Layer passivation (SEI), wanda ke ɗaure ions lithium, waɗanda ke da alhakin iya aiki kai tsaye,
- mafi girman ingancin cell tare da zafin jiki.
A) Hoton da ba a iya gani ba na NMC 532 foda B) hoton microscopic na farfajiyar lantarki bayan matsawa, C) ɗaya daga cikin sel da aka gwada 402035 a cikin jakar da ke kusa da tsabar kuɗin dalar Amurka biyu, DOWN, zane a hagu) lalata ƙwayoyin da aka gwada. idan aka kwatanta da baya na samfurin sel, DOWN, zane a hannun dama) tantanin halitta ta rayuwa tare da zafin jiki yayin caji (c) Jesse E.

Wannan duk yana da rikitarwa, amma tasirin yana da ban mamaki:
- Kashi 70 na iya aiki bayan zagayowar caji 3 a digiri 650 (kimanin kilomita miliyan 40),
- har zuwa kashi 90 na wutar lantarki bayan kilomita miliyan 3idan an kiyaye zafin jiki na tantanin halitta a 20 digiri Celsius kuma ana yin caji a 1 ° C (ƙarar baturi 1x, watau 40 kW tare da baturi 40 kWh, 100 kW tare da baturi 100 kWh, da dai sauransu).
Ba a sani ba idan aikace-aikacen haƙƙin mallaka yana nufin Tesla zai canja wurin NCA zuwa NCM. Ya zuwa yanzu, an ce ba a hukumance ba cewa ya kamata ƙwayoyin lithium-ion NCM su bayyana a cikin samfuran da aka yi a China.
> Kwalta (!) Zai ƙara ƙarfin aiki kuma yana hanzarta cajin batir lithium-ion.
Koyaya, yana da lafiya a faɗi cewa masana'anta na Californian suna shirye su ba da haƙƙin mallaka. Ta hanyar buga takardu akan sabbin abubuwan da ake amfani da su na lantarki, maiyuwa zai so ya hanzarta aikin duniya akan ƙwayoyin lithium masu zuwa.
Anan ga cikakken aikace-aikacen haƙƙin mallaka na Tesla (zazzage PDF NAN):
Lura daga masu gyara na www.elektrowoz.pl: yayin haɓaka wannan jigon, mun ji cewa ƙirƙirar motar lantarki ta Poland zai kasance da tsada sosai. Ba mu iya samun wani ambaton dioxazolones da sulfite ester nitriles akan Intanet ɗin Poland ba. Wannan yana nufin cewa tabbas babu wani mutum a Poland da zai iya fahimtar wannan aikace-aikacen haƙƙin mallaka da kuma ƙarshe.
