Hoʻohana ʻia ʻo Graphite i nā noi uila

ʻO Graphene ka mea a nā kānaka ʻepekema a me nā ʻenekinia e kapa nei he papa hoʻokahi o ka graphite ma ka pae atomika, a ke ʻōwili ʻia nei kēia mau papa lahilahi o ka graphene a hoʻohana ʻia i loko o nā nanotubes. ʻO kēia paha ma muli o ka conductivity uila kupaianaha a me ka ikaika a me ka paʻakikī o ka mea.

Ua kūkulu ʻia nā nanotubes kalapona o kēia lā me ka lakio lōʻihi-a-diameter a hiki i 132,000,000:1, ʻoi aku ka nui ma mua o nā mea ʻē aʻe. Ma waho aʻe o ka hoʻohana ʻia ʻana i ka nanotechnology, he mea hou ia i ka honua o nā semiconductors, pono e hoʻomaopopo ʻia ua hana ka hapa nui o nā mea hana graphite i nā papa kikoʻī o ka graphite no ka ʻoihana semiconductor no nā makahiki he ʻumi.

2. Nā Motika Uila, nā Mea Hana Hana a me nā Alternators

Hoʻohana pinepine ʻia ka mea kalapona kalapona i nā mīkini uila, nā mea hana, a me nā mea hoʻololi ma ke ʻano o nā pulumu kalapona. I kēia hihia, ʻo ka "pulmu" kahi mea e alakaʻi ai i ke au ma waena o nā uea paʻa a me ka hui pū ʻana o nā ʻāpana neʻe, a waiho pinepine ʻia ia i loko o kahi ʻau wili.

3. Hoʻokomo ʻana o ka Ion

Ke hoʻohana pinepine ʻia nei ka graphite i ka ʻoihana uila. Hoʻohana ʻia ia i ka hoʻokomo ʻana ion, nā thermocouples, nā kuapo uila, nā capacitors, nā transistors, a me nā pila pū kekahi.

ʻO ka hoʻokomo ʻana o ka ion kahi hana ʻenekinia kahi e hoʻolalelale ʻia ai nā ion o kahi mea kikoʻī i loko o kahi kahua uila a hoʻopili ʻia i loko o kekahi mea ʻē aʻe, ma ke ʻano he ʻano impregnation. ʻO ia kekahi o nā kaʻina hana nui i hoʻohana ʻia i ka hana ʻana o nā microchips no kā mākou kamepiula hou, a ʻo nā ʻātoma graphite kekahi o nā ʻano ʻātoma i hoʻokomo ʻia i loko o kēia mau microchips i hoʻokumu ʻia i ka silicon.

Ma waho aʻe o ke kuleana kūikawā o ka graphite i ka hana ʻana o nā microchips, ke hoʻohana ʻia nei nā hana hou i hoʻokumu ʻia i ka graphite e pani i nā capacitors a me nā transistors kuʻuna. Wahi a kekahi poʻe noiʻi, hiki i ka graphene ke lilo i mea koho ʻē aʻe i ka silicon holoʻokoʻa. He 100 mau manawa lahilahi ia ma mua o ka transistor silicon liʻiliʻi loa, alakaʻi i ka uila me ka ʻoi aku ka maikaʻi, a he mau waiwai exotic i hiki ke lilo i mea pono loa i ka helu quantum. Ua hoʻohana ʻia hoʻi ʻo Graphene i nā capacitors hou. ʻO ka ʻoiaʻiʻo, ʻoi aku ka ikaika o nā supercapacitors graphene he 20x mau manawa ma mua o nā capacitors kuʻuna (e hoʻokuʻu ana i 20 W/cm3), a he 3x paha ko lākou ikaika ma mua o nā pila lithium-ion kiʻekiʻe o kēia lā.

4. Nā pila

I ka wā e pili ana i nā pila (kelepona maloʻo a me ka lithium-Ion), ua lilo nā mea kalapona a me ka graphite i mea nui ma ʻaneʻi. I ke ʻano o kahi kelepona maloʻo kuʻuna (nā pila a mākou e hoʻohana pinepine ai i kā mākou mau lekiō, nā kukui uila, nā mea mamao, a me nā wati), ua hoʻopuni ʻia kahi electrode metala a i ʻole ke koʻokoʻo graphite (ka cathode) e kahi paʻi electrolyte pulu, a ua hoʻopaʻa ʻia nā mea ʻelua i loko o kahi cylinder metala.

Ke hoʻohana nei nā pila lithium-ion o kēia wā i ka graphite - ma ke ʻano he anode. Ua hoʻohana nā pila lithium-ion kahiko i nā mea graphite kuʻuna, akā naʻe i kēia manawa ua lilo ka graphene i mea maʻalahi ke loaʻa, ke hoʻohana ʻia nei nā anodes graphene - ʻo ka hapa nui no ʻelua mau kumu; 1. ʻoi aku ka maikaʻi o ka paʻa ʻana o nā anodes graphene i ka ikehu a 2. hoʻohiki ia i kahi manawa hoʻopiʻi he 10x ka wikiwiki ma mua o ka pila lithium-ion kuʻuna.

Ke lilo nei nā pila lithium-ion hiki ke hoʻouka hou ʻia i mea kaulana i kēia mau lā. Hoʻohana pinepine ʻia lākou i kēia manawa i kā mākou mau lako home, nā mea uila lawe lima, nā kamepiula lawe lima, nā kelepona akamai, nā kaʻa uila hybrid, nā kaʻa koa, a i nā noi aerospace pū kekahi.
