Mu myaka yashize, hamwe noguhindura imiterere yubukungu bwigihugu cyanjye, uburyo bwo gukoresha flake grafite buhoro buhoro buhinduka murwego rwingufu nshya nibikoresho bishya biragaragara, harimo ibikoresho bitwara ibintu (bateri ya lithium, selile lisansi, nibindi), inyongeramusaruro zamavuta hamwe na fluorine grafite nibindi bice byokoresha bizaba binini Igipimo cyo kwiyongera giteganijwe kurenga 25% mumashusho ya Fiteite.
Cyane cyane nishoramari rya bateri ya lithium-ion, icyifuzo cya flake grafite kizakomeza gushishikarizwa. Kuri bateri ya lithium-ion, flake grafite ntishobora kongera igihe cya bateri gusa, guteza imbere voltage ihamye, kongera ingufu, ariko kandi igabanya ibiciro bya batiri. Kubwibyo, flake grafite igira uruhare runini muri bateri. Biteganijwe ko muri 2020, umusaruro no kugurisha imodoka nshya zingufu mu gihugu cyanjye bizaba byibuze miliyoni 2. Niba imodoka ya miriyoni imwe ikoresha bateri ya lithium-ion, byibuze toni 50.000 na 60.000 za grafite yo mu rwego rwa batiri na toni 150.000 kugeza 180.000 za flake grafite. Biteganijwe ko umusaruro w’amashanyarazi ku isi uzarenga miliyoni 6, kandi bikaba bivugwa ko hakenewe toni 300.000 kugeza 360.000 za grafite yo mu rwego rwa batiri na 900.000 kugeza kuri miliyoni 1.08 za flake grafite.
Hatitawe ku kumenya niba ibiciro byiyongera bya flake grafite ari impulse yigihe gito, umuntu agomba kumenya neza ingamba zifatika za flake grafite, cyane cyane flake grafite. Hatitawe ku kumenya niba flake grafite izakomeza kuba igiciro cyinshi kandi cyamamaye cyane, iterambere ryayo ryihuse ntirihinduka. Kugirango duhangane n’ibura rishoboka ry’ibicuruzwa binini bya flake mu gihugu cyanjye mu gihe kiri imbere, ku ruhande rumwe, igihugu cyanjye gikwiye gushimangira mu buryo bukwiye ubushakashatsi bw’imiterere ya geologiya, ku rundi ruhande, guhindura uburyo bwo kwambara amabuye ya grafite no kongera ubushakashatsi n’iterambere ry’ibicuruzwa bishya bya grafite kugira ngo hamenyekane aho ikoranabuhanga ry’ibanze rigeze.
