Vhiki idzva uye bhatiri idzva. Iye zvino maelectrodes akagadzirwa nanoparticles emanganese uye titanium oxides panzvimbo yecobalt uye nickel.

Masayendisiti kubva kuYunivhesiti yeYokohama (Japan) akaburitsa bepa rekutsvagisa pamusoro pemasero umo cobalt (Co) uye nickel (Ni) zvakatsiviwa nemaokisi etitanium (Ti) uye manganese (Mn), pasi kusvika padanho rekukura. vari mumazana. nanometers. Iwo maseru anofanirwa kuve akachipa kugadzira uye kuve nekwaniso inofananidzwa kana nani pane yemazuva ano lithium-ion maseru.

Kusavapo kwecobalt uye nickel mu lithium-ion mabhatiri zvinoreva kuderera kwemitengo.

Tafura yezvinyorwa

• Kusavapo kwecobalt uye nickel mu lithium-ion mabhatiri zvinoreva kuderera kwemitengo.
  • Chii chakaitwa muJapan?

Masero e-lithium-ion akajairika anogadzirwa achishandisa akati wandei akasiyana matekinoroji uye akasiyana seti yezvinhu uye makemikari makomisheni anoshandiswa mune cathode. Mhando dzakanyanya kukosha ndeidzi:

• NCM kana NMC - i.e. kubva pane nickel-cobalt-manganese cathode; anoshandiswa nevazhinji vanogadzira mota dzemagetsi,
• NKA - kureva. kubva pane nickel-cobalt-aluminium cathode; Tesla anovashandisa
• LFP - inobva pane iron phosphates; BYD vashandise, mamwe maChinese brands anoashandisa mumabhazi,
• LCO - yakavakirwa pacobalt oxides; hatizive mugadziri wemota angadzishandisa, asi dzinoonekwa mumagetsi,
• LMOs - kureva. inobva kune manganese oxides.

Kuparadzaniswa kunorerutswa nekuvapo kwezvibatanidza zvinobatanidza matekinoroji (semuenzaniso, NCMA). Mukuwedzera, iyo cathode haisi yose, kunewo electrolyte uye anode.

> Samsung SDI ine lithium-ion bhatiri: nhasi graphite, nekukurumidza silicon, munguva pfupi lithium simbi masero uye huwandu hwe360-420 km muBMW i3.

Chinangwa chikuru chekutsvagisa kwakawanda pamasero e-lithium-ion ndechekuwedzera kugona kwavo (simba remagetsi), kuchengetedza kwekushanda uye kumhanya kwekuchaja uku vachiwedzera hupenyu hwavo hwesevhisi. apo kuderedza mari... Mari huru yekuchengetedza inobva mukubvisa cobalt uye nickel, zvinhu zviviri zvinodhura, kubva kumaseru. Cobalt inonyanya kunetsa nekuti inocherwa muAfrica, kazhinji ichishandisa vana.

Vagadziri vepamberi nhasi vari munhamba imwe chete (Tesla: 3 muzana) kana isingasviki gumi muzana.

Chii chakaitwa muJapan?

Vatsvakurudzi veYokohama vanoti vakakwanisa kutsiva zvachose cobalt uye nickel netitanium uye manganese. Kuti vawedzere kugona kwema electrode, vaigaya mamwe ma oxides (zvichida manganese netitanium) zvekuti zvikamu zvawo zvaive mazana emananomita muhukuru. Kukuya inzira inowanzo shandiswa nekuti, kupihwa huwandu hwezvinhu, inokwirisa nzvimbo yepamusoro yechinhu.

Uyezve, iyo yakakura nzvimbo yepamusoro, iyo yakawanda nooks uye kuputika muchimiro, iyo yakakura simba re electrode.

Kuburitswa kwacho kunoratidza kuti masayendisiti akabudirira kugadzira prototype yemasero ane zvivakwa zvinovimbisa uye vari kutsvaga vanobatana navo mumakambani ekugadzira. Danho rinotevera richava muedzo mukuru wekutsungirira kwavo, uchiteverwa nekuedza kugadzirwa kwehuwandu. Kana ma parameter avo achivimbisa, vachasvika kumotokari dzemagetsi kwete pamberi pe2025..
