Tesla ari kunyorera patent yemasero matsva eNMC. Mamirioni emakiromita anotyairwa uye kuderera kudiki
Tesla Canada yakanyorera masero matsva neNMC (nickel-manganese-cobalt) cathodes. Izvi zvinoratidzika kunge zvakafanana zvinhu zvakagadziridzwa lab yaJeff Dan kumugadziri izvo zvinobvumira mamirioni emamaira kuti afukidzwe nekupfeka kushoma uye kubvaruka.
Tesla kuchinja kubva kuNCA kuenda kuNMC?
Tesla parizvino anoshandisa lithium-ion masero ane NCA cathodes, i.e. nickel-cobalt-aluminium, ine isingasviki 10 muzana cobalt content, kanenge muTesla Model 3. Ichi chiitiko pachacho, nokuti mumasero akanakisisa emazuva ano NMC811 10 muzana cobalt cathodes. anoshandiswa - asi anouya mukushanda zvishoma nezvishoma, achibvisa NMC622 zvinhu.
> 2170 (21700) maseru muTesla 3 mabhatiri ari nani pane NMC 811 mune _future_
Sezvakavimbiswa naElon Musk, Tesla yemazuva ano inofanirwa kufamba kubva 0,48 kusvika 0,8 miriyoni makiromita pabhatiri. Zvisinei, munguva pfupi iri kutevera, angada kutyaira mamiriyoni 1,6 emakiromita pamagetsi ebheteri - izvi ndizvo zvinofanira kutsigira muviri uye powertrain yeTesla Model 3.
Uye pano anobatsirwa nekubudirira kwerabhoritari yaJeff Dan, iyo yakashandira Tesla kwekanguva uye iyo munaGunyana 2019 yakazvikudza yakazara nyowani electrolyte chemistry yelithium-ion masero ane NMC532 cathodes.
Nekuda kwekushandiswa kwe "crystal crystal" cathode uye electrolyte ine zvinowedzerwa zvinoshandiswa zvinowedzerwa mu dioxazolones uye sulfite ester nitriles, zvichienderana nekuumbwa kwe electrolyte (mabviro), zvinotevera zvakawanikwa:
- kunonoka kuderera kwesero nekuda kwekudzivirirwa kwekukura kweiyo passivating layer (SEI) inosunga lithium ions, iyo inokonzeresa capacitance,
- kukwirira kwesero kushanda sekushanda kwekushisa.

Harlow et al. / Chinyorwa cheElectrochemical Society
Zvese zvinonzwika zvakaoma, asi mhedzisiro yacho inoshamisa:
- 70 muzana kugona mushure me3 kuchaja kutenderera pa650 madhigirii (anenge mamiriyoni makumi mana emakiromita),
- simba rinosvika 90 muzana mushure memakiromita mamiriyoni matatukana kupisa kwesero kwaichengetwa pa20 degrees Celsius uye kuchaja kwakaitwa pa1 ° C (bhatiri simba 1x, i.e. 40 kW ne40 kWh bhatiri, 100 kW ine 100 kWh bhatiri, nezvimwewo).
Hazvizivikanwe kana iyo patent application yakaiswa zvinoreva kuti Tesla achaendesa iyo NCA kuNCM. Parizvino, zvave zvisina kutaurwa kuti NCM lithium-ion maseru anofanirwa kuoneka mumhando dzakagadzirwa kuChina.
> Asphalt (!) Ichawedzera huwandu uye nekukurumidza kuchaja kwe lithium-ion mabhatiri.
Nekudaro, isu tinogona kutaura chokwadi kuti mugadziri weCalifornian akagadzirira kupa mapatent ayo. Nekutsikisa basa pane zvitsva zve electrolyte additives, angangoda kukurumidza kuita basa renyika pane rinotevera-chizvarwa lithium masero.

Mucherechedzo weMharidzo www.elektrowoz.pl: Tichiri kugadzira dingindira iri, takanzwa kuti kugadzira mota yemagetsi yekuPoland kwaizodhura KWAZVO. Hatina kukwanisa kuwana chero kutaurwa kwe dioxazolones uye sulphite ester nitriles paInternet yePolish. Izvi zvinoreva kuti panogona kunge pasina munhu muPoland anogona kunzwisisa iyi patent application uye mhedzisiro yayo. Tine akawanda maPhD mukunyora, kushambadzira, philology, uye nhoroondo, asi kufambira mberi chaiko kuri kuitika kumwe kunhu, ipo pano, pamberi pemeso edu.
