Kuthekera kwapadera kwa graphite kuyendetsa magetsi kwinaku akutaya kapena kusamutsa kutentha kutali ndi zinthu zofunika kwambiri kumapangitsa kukhala chinthu chabwino kwambiri pamagetsi amagetsi kuphatikiza ma semiconductors, ma mota amagetsi, komanso kupanga mabatire amasiku ano.
Graphene ndi yomwe asayansi ndi mainjiniya amatcha gawo limodzi la graphite pamlingo wa atomiki, ndipo zigawo zoonda za graphenezi zikukulungidwa ndikugwiritsidwa ntchito mu nanotubes. Izi mwina chifukwa cha chidwi madutsidwe magetsi ndi zinthu zakuthupi mphamvu zapadera ndi kuuma.
Ma carbon nanotubes amakono amapangidwa molingana ndi kutalika kwa mita imodzi mpaka 132,000,000:1, yomwe ndi yokulirapo kuposa zinthu zina zilizonse . Kupatula kugwiritsidwa ntchito mu nanotechnology, yomwe ikadali yatsopano padziko lonse lapansi yama semiconductors, ziyenera kudziwidwa kuti opanga ma graphite ambiri akhala akupanga magiredi apadera amakampani opanga ma semiconductor kwazaka zambiri.
2. Magetsi amagetsi, ma jenereta ndi ma alternators
Mpweya wa carbon graphite umagwiritsidwanso ntchito kawirikawiri mu injini zamagetsi, majenereta, ndi ma alternator monga maburashi a carbon. Pachifukwa ichi, "burashi" ndi chipangizo chomwe chimayendetsa magetsi pakati pa mawaya osasunthika ndi mawaya osakanikirana, ndipo nthawi zambiri chimayikidwa muzitsulo zozungulira.
3. Ion Implantation
Graphite tsopano ikugwiritsidwa ntchito pafupipafupi m'makampani opanga zamagetsi. Ikugwiritsidwanso ntchito poyika ma ion, ma thermocouples, ma switch amagetsi, ma capacitor, transistors, ndi mabatire.
Kuyika kwa ion ndi njira yauinjiniya pomwe ma ion a chinthu china amachulukira mu gawo lamagetsi ndikukhudzidwa ndi chinthu china, ngati njira yoyimiritsa. Ndi imodzi mwazinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga ma microchip pamakompyuta athu amakono, ndipo maatomu a graphite ndi amodzi mwa mitundu ya ma atomu omwe amalowetsedwa mu ma microchips opangidwa ndi silicon.
Kuphatikiza pa ntchito yapadera ya graphite popanga tinthu tating'onoting'ono tating'onoting'ono, zatsopano za graphite zikugwiritsidwanso ntchito m'malo mwa ma capacitor achikhalidwe ndi ma transistors. Malinga ndi ofufuza ena, graphene ikhoza kukhala njira ina yopangira silicon palimodzi. Ndiwoonda kwambiri kuwirikiza ka 100 kuposa silicon transistor yaying'ono kwambiri, imayendetsa magetsi bwino kwambiri, ndipo ili ndi zinthu zachilendo zomwe zitha kukhala zothandiza kwambiri pamakompyuta a quantum. Graphene imagwiritsidwanso ntchito mu ma capacitor amakono. M'malo mwake, ma graphene supercapacitor akuti ndi amphamvu kuwirikiza 20x kuposa ma capacitor achikhalidwe (akutulutsa 20 W/cm3), ndipo amatha kukhala amphamvu kuwirikiza katatu kuposa mabatire amakono a lithiamu-ion .
4. Mabatire
Pankhani ya mabatire (maselo owuma ndi lithiamu-ion), zida za carbon ndi graphite zathandizanso pano. Pankhani ya cell youma (mabatire omwe timagwiritsa ntchito nthawi zambiri pamawailesi athu, ma tochi, ma remote, ndi mawotchi), electrode yachitsulo kapena graphite ndodo (cathode) imazunguliridwa ndi phala lonyowa la electrolyte, ndipo zonsezi zimayikidwa mkati. silinda yachitsulo .
Masiku ano mabatire a lithiamu-ion akugwiritsanso ntchito graphite - ngati anode. Mabatire akale a lithiamu-ion adagwiritsa ntchito zida zachikhalidwe za graphite, komabe popeza graphene ikupezeka mosavuta, ma graphene anode akugwiritsidwa ntchito m'malo mwake - makamaka pazifukwa ziwiri; 1. ma graphene anode amakhala ndi mphamvu bwino ndipo 2. imalonjeza nthawi yolipira yomwe ili 10x mwachangu kuposa batire yachikhalidwe ya lithiamu-ion.
Mabatire owonjezera a lithiamu-ion akukhala otchuka masiku ano. Masiku ano amagwiritsidwa ntchito nthawi zambiri m'zida zathu zapakhomo, zamagetsi zam'manja, ma laputopu, mafoni anzeru, magalimoto amagetsi osakanizidwa, magalimoto ankhondo, komanso ntchito zam'mlengalenga.
