Lekhetlo la pele ka koloing, betri ea graphene? GAC: E, ho Aion V re ntse re e leka hona joale. Ho tjhaja 6C!
GAC ea China e re e amohetse lengolo la tšireletso ea sesole bakeng sa "betri ea graphene". E tlameha ho lumella ho tjhaja ka makhetlo a mabeli matla a kajeno: ha kajeno tlhōrō ea tsoelo-pele ea motlakase e le 3-3,5 C (matla = 3-3,5 x matla a betri), ho boleloa hore betri ea graphene koloing ea GAC e lumella tšebeliso ea 6.

Hopola: ka libeteri tsa lithium-ion tsa khale tse nang le electrolyte ea metsi, li-anode hangata li entsoe ka carbon kapa carbon e entsoeng ka silicon. Li-cathode, le tsona, li ka etsoa ka lithium-nickel-manganese-cobalt (NCM) kapa lithium-nickel-cobalt-aluminium (NCA). Nakong ea ts'ebetso ea betri, li-ion tsa lithium li tsamaea pakeng tsa li-electrode tse peli, li fana kapa li amohela lielektrone. Sebaka sa graphene se hokae ho see sohle?
Ha e le hantle, ha e laetsoe ka matla a phahameng, liathomo tsa lithium li ka etsa li-protrusions tse bitsoang dendrites.

Joale ha re feteleng ho phatlalatso ea GAC. Moetsi oa Lechaena hajoale o ntse a leka libetri tsa graphene moetsong oa Aion V o Mohe, China. Kamoo ho bonahalang kateng, o ile a fumana lengolo la tšireletso la sesole ho tsona, mohlomong le li lumella hore li sebelisoe likoloing tsa motlakase. Matla a matla a libeteri tsa graphene e lokela ho ba joalo 0,28 kWh / lik'hilograma, eo lisele tse tsoetseng pele tsa NCM li fanang ka tsona - ha ho na katleho mona (mohloli).

Bohelehele bo boholo ka ho fetisisa boholo ba matla a ho tjhaja. Ho lokela hoba jwalo 6 C, ke. betri e nang le bokhoni ba ho re, 64 kWh - joalo ka Kia e-Niro - re ka tjhaja ka matla a maholo a 384 kW.
