Li- and anodes za bateri zigereranya igikorwa vyihuta cane- ubuhinga bwo gukura, n’ibisabwa vyongererako 8-8,5% ku mwaka biterwa n’uguhingura imodoka zikoreshwa n’umuyagankuba

Isoko ry’isi yose ry’ivy’ubuhinga bwa none ryashitse ku madolari 7-8 miliyaridi mu 2024, kandi ritegerezwa gukura rishika ku madolari 13-16 miliyaridi mu 2032-2034 .

Ivyo bikoresho bitanga 20-25 kg CO ku kg y'ibikoresho, 4x hejuru y'ivyo gukora graphite, bikaba ari vyo bituma haba umukazo w'ubuzima buramba .

Aziya-Pacific, cane cane Ubushinwa, ni yo iganza 42-65% vy'ivyo kw'isi yose, naho ubushobozi bwa Amerika bwa ruguru n'ubw'i Buraya buriko buragwira

Ivyo bikoresho vy’ubuhinga bwa none biguma ari vyo bikoreshwa cane ku 35-43% vy’abasaba, naho nyene gukoresha amabateri ariko arakura ningoga

Igishushanyo c'umubiri gitanga ubusuku n'uguhuza ugereranyije n'ivyuma vy'umubiri ariko bigura 2-3x vyinshi kugira ngo bive
