Hoʻohana ʻia ka Graphite ma nā polokalamu uila

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

Kūkulu ʻia nā nanotubes kalapona o kēia lā me ka lākiō 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 ʻana i ka nanotechnology, he mea hou i ka honua o nā semiconductor, pono e hoʻomaopopo ʻia ʻo ka hapa nui o nā mea hana graphite i hana i nā māka kikoʻī o ka graphite no ka ʻoihana semiconductor no nā makahiki he mau makahiki.

2. Nā Motors Uila, Nā Generators a me nā Alternators

Hoʻohana pinepine ʻia nā mea kalapona graphite i nā kaʻa uila, nā mea hana, a me nā mea hoʻololi i ke ʻano o nā pulu kalapona. I kēia hihia, ʻo ka "brush" kahi mea hana e hoʻokele i ka manawa ma waena o nā uwea paʻa a me ka hui pū ʻana o nā ʻāpana neʻe, a ua hoʻokomo pinepine ʻia i loko o kahi ʻano huila.

3. Hookomo Ion

Ke hoʻohana ʻia nei ka graphite me ka nui o ka pinepine i ka ʻoihana uila. Hoʻohana ʻia ia i ka implantation ion, thermocouple, nā hoʻololi uila, capacitors, transistors, a me nā pākahi pū kekahi.

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

Ma waho aʻe o ke kuleana kūʻokoʻa o ka graphite i ka hana ʻana i nā microchips, ke hoʻohana ʻia nei nā mea hou e pili ana i ka graphite e pani i nā capacitors a me nā transistors. Wahi a kekahi poʻe noiʻi, hiki i ka graphene ke hoʻololi i ke kilika. He 100 manawa ʻoi aku ka lahilahi ma mua o ka transistor silicon liʻiliʻi loa, hoʻokele pono i ka uila, a loaʻa iā ia nā waiwai exotic i hiki ke hoʻohana nui i ka computing quantum. Ua hoʻohana pū ʻia ʻo Graphene i nā capacitors hou. ʻO ka ʻoiaʻiʻo, ʻo ka graphene supercapacitors i manaʻo ʻia he 20x mau manawa ʻoi aku ka ikaika ma mua o nā capacitor kuʻuna (hoʻokuʻu ʻia 20 W/cm3), a ʻoi aku paha ka ikaika o 3x mau manawa ma mua o nā pākahi lithium-ion o kēia lā.

4. Nā ʻōhua

I ka wā e pili ana i nā pila (kahi maloʻo a me ka lithium-Ion), ʻo nā mea kalapona a me nā mea graphite kekahi i mea hana ma ʻaneʻi. I ka hihia o ke kelepona maloʻo kuʻuna (nā ʻokoʻa a mākou e hoʻohana pinepine ai i kā mākou lekiō, nā kukui uila, nā mamao, a me nā wati), ua hoʻopuni ʻia kahi electrode metala a i ʻole graphite rod (ka cathode) e kahi paʻi electrolyte mākū, a ua hoʻopili ʻia ʻelua i loko. he pahu metala .

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

Ke hoʻonui nui ʻia nei nā pākahi lithium-ion rechargeable i kēia mau lā. Hoʻohana pinepine ʻia lākou i kā mākou mau mea hana hale, nā uila uila, nā kamepiula, nā kelepona akamai, nā kaʻa uila hybrid, nā kaʻa koa, a me nā noi aerospace pū kekahi.
