Beke e ncha, betri e ncha. Hona joale li-electrode tse entsoeng ka nanoparticles tsa manganese le titanium oxides sebakeng sa cobalt le nickel.

Bo-rasaense ba Univesithing ea Yokohama (Japan) ba ile ba hatisa pampiri ea lipatlisiso ka lisele tseo cobalt (Co) le nickel (Ni) li ileng tsa nkeloa sebaka ke titanium (Ti) le manganese (Mn) oxides, e sithabetseng ho isa tekanyong eo boholo ba karoloana e leng eona. e lekantsoeng ka makholo. li-nanometers. Lisele li lokela ho ba theko e tlase ho li etsa le ho ba le bokhoni bo ka bapisoang le kapa bo betere ho feta lisele tsa kajeno tsa lithium-ion.

Ho ba sieo ha cobalt le nickel ka libeteri tsa lithium-ion ho bolela litšenyehelo tse tlaase.

Lethathamo la tse kahare

• Ho ba sieo ha cobalt le nickel ka libeteri tsa lithium-ion ho bolela litšenyehelo tse tlaase.
  • Ho fihletsoe eng Japane?

Lisele tse tloaelehileng tsa lithium-ion li etsoa ho sebelisoa theknoloji e fapaneng e fapaneng le lihlopha tse fapaneng tsa lisele le metsoako ea lik'hemik'hale e sebelisoang ka har'a cathode. Mefuta e tsebahalang haholo ke:

• NCM kapa NMC - ke hore. e thehiloeng ho nickel-cobalt-manganese cathode; li sebelisoa ke bahlahisi ba bangata ba likoloi tsa motlakase,
• NKA - ke hore. e thehiloeng ho nickel-cobalt-aluminium cathode; Tesla oa li sebelisa
• LFP - e thehiloeng ho phosphates ea tšepe; BYD li sebelisa, lihlahisoa tse ling tsa China li li sebelisa ka libeseng,
• LCO - e thehiloeng ho cobalt oxides; ha re tsebe moetsi oa likoloi ea ka li sebelisang, empa li hlaha ka lisebelisoa tsa elektroniki,
• LMOs - ke hore. e thehiloeng ho manganese oxides.

Karohano e nolofatsoa ke boteng ba lihokelo tse hokahanyang mahlale a morao-rao (mohlala, NCMA). Ho phaella moo, cathode hase ntho e 'ngoe le e' ngoe, ho boetse ho na le electrolyte le anode.

> Samsung SDI e nang le betri ea lithium-ion: kajeno graphite, haufinyane silicon, haufinyane lisele tsa tšepe tsa lithium le sebaka sa 360-420 km ho BMW i3

Sepheo se seholo sa lipatlisiso tse ngata ka lisele tsa lithium-ion ke ho eketsa matla a bona (matla a matla), polokeho ea ts'ebetso le lebelo la ho tjhaja ha ba ntse ba atolosa bophelo ba bona ba tšebeletso. ha a ntse a fokotsa litšenyehelo. Ho boloka litšenyehelo tse ka sehloohong ho tsoa ka ho tlosa cobalt le nickel, likarolo tse peli tse theko e boima ka ho fetisisa, tse tsoang liseleng. Cobalt e na le bothata haholo hobane e rafshoa haholo-holo Afrika, hangata e sebelisa bana.

Baetsi ba tsoetseng pele ka ho fetisisa kajeno ba falletse ho linomoro tse le 'ngoe (Tesla: liperesente tse 3) kapa ka tlase ho liperesente tse 10.

Ho fihletsoe eng Japane?

Bafuputsi ba Yokohama ba bolela seo ba ile ba khona ho fetola cobalt le nickel ka ho feletseng ka titanium le manganese. Ho eketsa matla a li-electrode, li ile tsa sila li-oxide tse ling (mohlomong manganese le titanium) e le hore likaroloana tsa tsona li be boholo ba li-nanometer tse makholo a 'maloa. Ho sila ke mokhoa o sebelisoang hangata hobane, ha ho nahanoa ka bongata ba thepa, e eketsa bokaholimo ba thepa.

Ho feta moo, sebaka se seholo sa holim'a metsi, li-nooks le li-crannies tse ngata ka moralo, ho ba le bokhoni bo boholo ba electrode.

Ho lokolloa ho bontša hore bo-rasaense ba atlehile ho theha sele ea prototype e nang le thepa e tšepisang, 'me hona joale ba batla balekane ba lik'hamphani tsa tlhahiso. Mohato o latelang e tla ba teko ea boima ba mamello ea bona, e lateloe ke teko ea tlhahiso ea bongata. Haeba li-parameter tsa bona li ts'episa, ba tla fihla likoloing tsa motlakase pele ho 2025..
