Mbega graphite ikozwe mu bihimba vy’umubiri yoshobora gusubirwamwo mu mabati ya kera?

Graphite y’ubuhinga bushasha ishobora gusubirwamwo mu ma bateri ya Li-ion yakoreshejwe, ariko iyo nzira iragoye mu vy’ubuhinga kandi ntaco imaze mu vy’ubutunzi mu bihe vy’ubu. Gukuraho ibintu bifatanya, ibisigarira vy’amazi, no gusubizaho imiterere y’amabuye y’agaciro bisaba gukora cane bishobora gutwara amahera menshi kuruta guhingura ibintu bishasha, naho ivyo vyoshobora guhinduka uko ubuhinga bwo gusubira gukoresha ibintu bugenda buratera imbere.

Ivyiza vyo gutwara

Synthetic graphite is manufactured carbon material produced by heating petroleum coke to 2,500-3,000°C, creating uniform structure with >99.9% ubusuku

Li-ion battery anodes zigereranya ibikorwa vyihuta-kura, n'ugusaba kwiyongera 8-8.5% ku mwaka bivuye ku guhingura imodoka zikoresha umuyagankuba

Isoko ry’isi yose ry’amabuye y’agaciro yitwa graphite ryashitse ku madolari 7-8 miliyaridi mu 2024 kandi ritegerezwa gukura gushika ku madolari 13-16 miliyaridi mu 2032-2034 .

Umusaruro utanga ibiro 20-25 vya CO2 ku kilo c’ibikoresho, 4x kuruta ugutunganya graphite kavukire, bikaba bituma habaho umukazo w’ubuzima buramba

Aziya{0}}Pasifike, cane cane Ubushinwa, ni yo igenzura ibikorwa vy'ubuhinga n'ibice 42-65% vy'ivyo isi yose itanga, naho ubushobozi bwa Amerika y'Uburaruko n'Uburayi buriko buragwira

Ivyuma vy’amashanyarazi biguma ari vyo bikoreshwa cane ku 35-43% vy’abasaba, naho nyene ibikorwa vy’amabateri biriko birakura cane

Graphite y’ubuhinga itanga ubusuku n’ubumwe bwiza cane ugereranije n’iyi graphite kavukire ariko igura incuro 2-3 kugira ngo ikorwe .
