Nava: Li-electrode tsa rona tsa nanotube li na le matla a makhetlo a 3 'me li fana ka matla a makhetlo a 10 liseleng tsa lithium-ion.
Beke e ncha, betri e ncha. Moetsi oa supercapacitor oa Fora Nawa o re e se e qalile tlhahiso ea li-electrode tse ncha tsa nanotube bakeng sa libeteri tsa lithium-ion. Ho nahanoa hore ka lebaka la tokisetso e tšoanang ea li-nanotubes, li ka boloka tefiso e fetang makhetlo a mararo ho feta carbon anode.
Li-anode tse ncha tsa 3D tse tsoang ho Nawa: e matla, e betere, e potlakile, e matla
Li-anode tsa morao-rao tsa lithium-ion li entsoe haholo-holo ka graphite kapa activated carbon (kapa esita le carbon activated ho tloha graphite) hobane sebopeho sa bona sa porous se lumella ho boloka li-ion tse ngata. Ka linako tse ling carbon e kopantsoe le silicon 'me e pota-potiloe ke nanocoating ho fokotsa ho ruruha ha thepa.
U se u ntse u utloa ka lisebelisoa tsa ho sebelisa silicon e hloekileng, ho bolela Tesla kapa Samsung SDI.
> Likarolo tse ncha tsa Tesla: fomate ea 4680, anode ea silicon, "diameter e nepahetseng", tlhahiso ea letoto ka 2022.
Nava o re sebopeho sa carbon se rarahane haholo bakeng sa li-ion tse tsamaeang. Sebakeng sa khabone, k'hamphani e batla ho sebelisa carbon nanotubes, eo ho tlalehoang hore e se e ntse e sebelisoa ho li-supercapacitor tsa moetsi. Li-nanotubes tse hlophisitsoeng ka mokhoa o bapileng "notches" tse otlolohileng tseo li-ion li ka lulang ho tsona hantle. Ka ho toba:
Ho ka nkoa hore li-nanotubes tsohle tsa anode li fumaneha ka tsela eo li-ion li tsamaeang ka bolokolohi pakeng tsa tsona ho fihlela ho khethoa sebaka se loketseng. "Ntle le ho pota-pota meaho e nang le porous ea anode ea khale, li-ion li tla tsamaea li-nanometer tse seng kae feela ho e-na le li-micrometer, joalo ka ha ho le joalo ka li-electrode tsa khale," Nava o re.
Polelo ea ho qetela e bontša hore nanotubes e ka boela ea sebetsa e le li-cathodes - mosebetsi oa tsona o tla itšetleha ka thepa e tla ba holim'a tsona. Nef ha e thibele ho sebelisa silicon hobane carbon nanotubes e tla e koala joaloka cage, kahoo mohaho o ke ke oa ba le monyetla oa ho ruruha. Bothata ba Crush bo rarollotsoe!
> Sebelisa lisele tsa lithium-ion tse seng li entsoe ka silicon anode. E tjhaja kapele ho feta hydrogen refueling
Hona ho ne ho tla ba joang ka litekanyo tsa lisele tse sebelisang nanotubes? Hantle, ba ne ba tla lumella:
- tshebediso ya Ka makhetlo a 10 ho feta matla a ho tjhaja le ho ntša matlaeng hona joale
- popo libeteri tse nang le matla a matla ka makhetlo a 2-3 holimo ho tloha mehleng ea kajeno,
- ho lelefatsa bophelo ba betri ka makgetlo a mahlano kapa a leshomehobane nanotubes e ke ke ea lumella lits'ebetso tse senyang lisele tsa lithium-ion (mohloli).
Mokhoa ona oa ho hokahanya li-nanotubes ka tatellano e lokela ho ba bonolo hanyane, ho thoeng ke mokhoa o ts'oanang o sebelisetsoang ho roala likhalase le lisele tsa photovoltaic tse nang le anti-reflective coating. Nawa e ithorisa ka hore e khona ho holisa li-nanotube tse bapileng ka lebelo ho fihla ho li-micrometer tse 100 (0,1 mm) ka motsotso - mme e sebelisa theknoloji ena ho li-supercapacitor tsa eona.
Haeba lipolelo tsa Nava e ne e le 'nete' me li-electrode tse ncha li ile tsa rekisoa, sena se ne se tla bolela ho rona:
- likoloi tsa motlakase li bobebe ho feta likoloi tse tukang ka hare empa li na le mefuta e mengata,
- bokhoni ba ho lefisa basebetsi ba motlakase ka matla a 500 ... 1 ... 000 kW, e khuts'oane ho feta ho tlatsa mafura,
- keketseho ea lik'hilomithara tsa motlakase ntle le tlhokahalo ea ho nkela betri sebaka ho tloha ho 300-600 ho ea ho lik'hilomithara tse limilione tse 1,5-3-6,
- ha o ntse o boloka boholo ba betri ea hajoale: e ka nchafatsoa, e re, hang ka libeke tse ling le tse ling tse peli.
Molekane oa pele oa Navah ke moetsi oa libeteri oa Fora Saft, e sebelisanang le PSA Group le Renault e le karolo ea European Battery Alliance.
