Maka oge mbụ n'ime ụgbọ ala, batrị graphene? GAC: Ee, na Aion V anyị na-anwale ya ugbu a. Na-akwụ ụgwọ 6C!

GAC nke China na-ekwu na ọ natara asambodo nchekwa ndị agha maka "batrị graphene." A na-atụ anya ikwe ka ịchaji okpukpu abụọ karịa ike taa: na ọganihu eletrik kachasị elu taa bụ 3-3,5 C (ike = 3-3,5 x batrị), a na-ekwu na batrị graphene dị na ụgbọ ala GAC ​​na-enye ohere iji 6 C.

• GAC Aion V - ihe anyị maara

N'ịkọwapụta, batrị lithium-ion mmiri mmiri kpochapụwo na-enwekarị anodes nke carbon ma ọ bụ carbon doped na silicon. Cathodes, n'aka nke ya, nwere ike iji lithium-nickel-manganese-cobalt (NCM) ma ọ bụ lithium-nickel-cobalt-aluminum (NCA). N'oge ọrụ batrị, ion lithium na-agagharị n'etiti electrodes abụọ ahụ, na-enye ma ọ bụ na-anata electrons. Ebe graphene dabara na ihe a niile?

Ọfọn, mgbe ejiri ike dị elu jupụta, atom lithium nwere ike ịmepụta ntule a na-akpọ dendrites.
