Izi ndi nthawi yachiwiri yosangalatsa kwambiri yosinthira zinthu m'mbiri ya petroleum coke

"Epic" Yamakono: Kuikidwa kwa Mfumu mu Nthawi ya Lithium Battery

Izi ndi nthawi yachiwiri yosangalatsa kwambiri yosinthira zinthu m'mbiri ya petroleum coke.

Chiyambi

M'zaka za m'ma 1990, Sony Corporation idapambana kugulitsa mabatire a lithiamu-ion. Kupeza zinthu zoyenera za electrode yoipa kunakhala kofunika kwambiri. Asayansi adayesa zinthu zosiyanasiyana za kaboni.

Chifukwa chiyani Petroleum Coke?

Pambuyo pa chithandizo cha graphitization, petroleum coke imakhala ndi kapangidwe ka graphite kokhala ndi zigawo zomwe zimapereka "hotelo" yoyenera yoyika ndi kutulutsa ma ayoni a lithiamu. Ili ndi zabwino zambiri monga mphamvu yayikulu, nthawi yayitali yozungulira, komanso nsanja yokhazikika yamagetsi.

Kuchokera ku Lab kupita ku Makampani Padziko Lonse

Gawo Loyambirira (1990 - 2000)

Makampani aku Japan (monga Hitachi Chemical) adatsogolera paukadaulo, ndikukhazikitsa momwe ma electrode opanda graphite omwe amagwiritsa ntchito mafuta a coke amakhalira.

Kukula (2000 - 2010)

Chifukwa cha kutchuka kwa mafoni ndi ma laputopu, kufunikira kwa mafoni kunakula kwambiri. Makampani aku Korea ndi aku China adakwanitsa, zomwe zidapangitsa kuti pakhale kufalikira kwamphamvu kwa mphamvu zopangira zinthu zamagetsi zopanda ma elekitirodi padziko lonse lapansi. Kufunika kwa needle coke yapamwamba kwambiri kunakula kwambiri.

Mpikisano Wamphamvu (2010s – Pakadali pano)

Mafunde a magalimoto amagetsi padziko lonse lapansi adalowa. Mabatire amagetsi adayika zofunikira kwambiri pa magwiridwe antchito, mtengo, ndi kusinthasintha kwa zinthu zoyipa za ma electrode. Izi zidayambitsa:

• Mpikisano wa Ukadaulo: Mpikisano ndi kuphatikizana pakati pa graphite yopangidwa (yopangidwa kuchokera ku needle coke), graphite yachilengedwe, ndi ma electrode opanda silicon-carbon.
• Kusakanikirana kwa Unyolo Wogulira: Mpikisano wapadziko lonse wa zinthu zapamwamba za singano coke unakula kwambiri. Mtengo wake ndi kukhazikika kwa kupezeka kwake zinakhala chimodzi mwa zinthu zazikulu zomwe zimakhudza mtengo wa mabatire.

Chidule: Maphunziro ochokera ku Mbiri

Mbiri ya coke ya petroleum yokhala ndi graphitized ndi nkhani ya mafakitale ya "zatsopano zomwe zimayendetsedwa ndi mavuto komanso kufunika kosinthidwa."

Zinayamba ngati "vuto" pa kuyeretsa mafuta (kutaya zinyalala).

Kudzera mu "chothandizira" cha nkhondo (kufunika kwa ng'anjo zamagetsi) ndi "chakudya" cha mafakitale oyambira (makampani a aluminiyamu), idamaliza kukweza kwake koyamba.

Pansi pa "kukakamizidwa" kwa kuteteza chilengedwe ndi "kusintha" kwa mphamvu, idagwiritsa ntchito mwayi wakale ndipo pomaliza pake idavekedwa ufumu mu nthawi ya digito komanso kusintha kwa magalimoto amagetsi.
