Tšebeliso ea Graphite Likopong tsa Elektronike

Graphene ke seo bo-rasaense le lienjineri ba se bitsang lera le le leng la graphite boemong ba athomo, 'me likarolo tsena tse tšesaane tsa graphene li ntse li phuthoa 'me li sebelisoa li-nanotubes. Sena se ka etsahala ka lebaka la ho khahleha ha motlakase le matla a ikhethang le ho satalla ha thepa.

Li-carbon nanotubes tsa kajeno li hahiloe ka karolelano ea bolelele-ho-diameter ho fihla ho 132,000,000:1, e leng kholo ho feta ntho leha e le efe e 'ngoe . Ntle le ho sebelisoa ho nanotechnology, e ntseng e le ncha lefatšeng la li-semiconductors, ho lokela ho hlokomeloa hore bahlahisi ba bangata ba graphite ba 'nile ba etsa limaraka tse khethehileng tsa graphite bakeng sa indasteri ea semiconductor ka lilemo tse mashome.

2. Likoloi tsa Motlakase, Lijenereithara le Li-alternator

Lisebelisoa tsa carbon graphite li boetse li sebelisoa hangata ho li-motor tsa motlakase, lijenereithara le li-alternator ka mokhoa oa borashe ba carbon. Tabeng ena "borashe" ke sesebelisoa se tsamaisang hona joale pakeng tsa lithapo tse emeng le motsoako oa likarolo tse tsamaeang, 'me hangata li kenngoa ka har'a shaft e potolohang.

3. Ho kenngoa ha Ion

Graphite e se e sebelisoa ka makhetlo a mangata indastering ea lisebelisoa tsa elektroniki. E ntse e sebelisoa ho kenya li-ion, li-thermocouples, li-switch tsa motlakase, li-capacitor, li-transistors le libeteri.

Ho kenngoa ha Ion ke ts'ebetso ea boenjiniere moo li-ion tsa thepa e itseng li potlakisang lebaleng la motlakase 'me li ameha ho tse ling, joalo ka mokhoa oa ho kenya. Ke e 'ngoe ea mekhoa ea mantlha e sebelisoang tlhahisong ea li-microchips bakeng sa likhomphutha tsa rona tsa sejoale-joale,' me liathomo tsa graphite hangata ke e 'ngoe ea mefuta ea liathomo tse kentsoeng ka har'a li-microchips tsena tse thehiloeng ho silicon.

Ntle le karolo e ikhethang ea graphite tlhahisong ea li-microchips, mekhoa e mecha ea graphite e se e sebelisoa ho nkela li-capacitor tsa setso le transistors hape. Ho ea ka bafuputsi ba bang, graphene e ka 'na ea e-ba mokhoa o mong oa ho sebelisa silicon ka ho feletseng. E tšesaane ka makhetlo a 100 ho feta silicon transistor e nyane ka ho fetisisa, e tsamaisa motlakase ka mokhoa o atlehileng haholoanyane, 'me e na le lisebelisoa tse ikhethang tse ka thusang haholo komporong ea quantum. Graphene e boetse e sebelisitsoe ho li-capacitor tsa sejoale-joale. Ebile, li-graphene supercapacitor ho nahanoa hore li matla ka makhetlo a 20 ho feta li-capacitor tsa setso (tse lokollang 20 W/cm3), 'me li kanna tsa ba matla ka makhetlo a 3 ho feta libetri tsa kajeno tsa lithium-ion tse matla haholo.

4. Libetri

Ha ho tluoa tabeng ea libeteri (sele e omileng le lithium-Ion), lisebelisoa tsa carbon le graphite le tsona li thusitse mona. Tabeng ea sele ea setso e omileng (libetri tseo re atisang ho li sebelisa liea-le-moeeng tsa rona, litoche, li-remote, le lioache), elektrode ea tšepe kapa graphite rod (cathode) e pota-potiloe ke pente e mongobo ea electrolyte, 'me ka bobeli li kenngoa ka hare. moqomo oa tšepe .

Libetri tsa kajeno tsa lithium-ion le tsona li sebelisa graphite - joalo ka anode. Libetri tsa khale tsa lithium-ion li ne li sebelisa lisebelisoa tse tloaelehileng tsa graphite, leha ho le joalo hona joale kaha graphene e ntse e fumaneha habonolo, graphene anode e se e sebelisoa ho e-na le hoo - haholo-holo ka mabaka a mabeli; 1. graphene anode e tšoara matla hamolemo le 2. e tšepisa nako ea tefiso e lebelo ka makhetlo a 10 ho feta betri ea setso ea lithium-ion.

Libetri tsa lithium-ion tse nchafalitsoeng li ntse li tsebahala haholo matsatsing ana. Hona joale li sebelisoa hangata lisebelisoa tsa rona tsa lapeng, lisebelisoa tsa elektroniki tse nkehang, lilaptop, lifono tse bohlale, likoloi tsa motlakase tse nyalisitsoeng, likoloi tsa sesole, le lits'ebetsong tsa sefofane.
