Iviki elisha nebhethri elisha. Manje ama-electrode enziwe ngama-nanoparticles e-manganese ne-titanium oxides esikhundleni se-cobalt ne-nickel.

Ososayensi abavela eNyuvesi yaseYokohama (eJapane) bashicilele iphepha lokucwaninga ngamaseli lapho i-cobalt (Co) ne-nickel (Ni) ithathelwe indawo yi-oxides ye-titanium (Ti) kanye ne-manganese (Mn), eyafika ezingeni lapho ubukhulu bezinhlayiyana. zingamakhulu. ama-nanometers. Amaseli kufanele ashibhe ukuwenza futhi abe namandla afanayo noma angcono kunamaseli e-lithium-ion esimanje.

Ukungabikho kwe-cobalt ne-nickel kumabhethri e-lithium-ion kusho izindleko eziphansi.

Uhlu lokuqukethwe

• Ukungabikho kwe-cobalt ne-nickel kumabhethri e-lithium-ion kusho izindleko eziphansi.
  • Yini eye yafinyelelwa eJapane?

Amaseli e-lithium-ion ajwayelekile akhiqizwa kusetshenziswa ubuchwepheshe obuhlukahlukene obuhlukahlukene kanye namasethi ahlukene wezakhi kanye namakhemikhali asetshenziswa ku-cathode. Izinhlobo ezibaluleke kakhulu yilezi:

• I-NCM noma i-NMC - i.e. esekelwe ku-nickel-cobalt-manganese cathode; zisetshenziswa iningi labakhiqizi bezimoto zikagesi,
• NKA - i.e. esekelwe ku-nickel-cobalt-aluminium cathode; UTesla uyazisebenzisa
• I-LFP - esekelwe ku-iron phosphates; BYD basebenzise, ​​ezinye izinhlobo zamaShayina zizisebenzisa emabhasini,
• I-LCO - esekelwe ku-cobalt oxides; asazi umkhiqizi wezimoto ongazisebenzisa, kodwa zivela kuma-electronics,
• Ama-LMO - i.e. ngokusekelwe kuma-manganese oxides.

Ukwehlukana kwenziwa lula ngokuba khona kwezixhumanisi ezixhuma ubuchwepheshe (isibonelo, i-NCMA). Ngaphezu kwalokho, i-cathode akuyona yonke into, kukhona i-electrolyte ne-anode.

> I-Samsung SDI enebhethri ye-lithium-ion: namuhla i-graphite, maduze i-silicon, maduze nje amaseli ensimbi e-lithium kanye nohlu lwama-360-420 km ku-BMW i3

Umgomo oyinhloko wocwaningo oluningi lwamaseli e-lithium-ion ukukhulisa amandla abo (ukuminyana kwamandla), ukuphepha kokusebenza kanye nesivinini sokushaja ngenkathi kunwetshwa impilo yabo yesevisi. ngenkathi kunciphisa izindleko... Izindleko eziyinhloko zokonga zivela ekulahleni i-cobalt ne-nickel, izakhi ezimbili ezibiza kakhulu, kumaseli. I-Cobalt iyinkinga ikakhulukazi ngoba imayini ikakhulukazi e-Afrika, ngokuvamile isebenzisa izingane.

Abakhiqizi abathuthuke kakhulu namuhla banedijithi eyodwa (i-Tesla: amaphesenti angu-3) noma ngaphansi kwamaphesenti angu-10.

Yini eye yafinyelelwa eJapane?

Abacwaningi baseYokohama bathi bakwazile ukushintsha ngokuphelele i-cobalt ne-nickel nge-titanium ne-manganese. Ukuze kwandiswe amandla ama-electrode, agaya ama-oxide athile (mhlawumbe i-manganese ne-titanium) ukuze izinhlayiya zawo zibe ama-nanometer angamakhulu amaningana ngobukhulu. Ukugaya kuyindlela evame ukusetshenziswa ngoba, uma kubhekwa umthamo wezinto ezibonakalayo, kukhulisa indawo engaphezulu yento.

Ngaphezu kwalokho, lapho indawo engaphezulu ikhudlwana, ama-nooks amaningi kanye nokuqhekeka kwesakhiwo, amandla amakhulu e-electrode.

Ukukhishwa kubonisa ukuthi ososayensi baphumelele ekudaleni i-prototype yamaseli anezakhiwo ezithembisayo futhi manje bafuna ozakwethu ezinkampanini ezikhiqizayo. Isinyathelo esilandelayo kuzoba ukuhlolwa okukhulu kokukhuthazela kwabo, okulandelwa umzamo wokukhiqiza ngobuningi. Uma amapharamitha abo ethembisa, bazofinyelela ezimotweni zikagesi ngaphambi kuka-2025..
