Umusha emotweni enebhethri le-graphene? I-GAC: Yebo, ku-Aion V siyayihlola njengamanje. Iyashaja 6 C!
I-GAC yaseShayina ithi isithole isitifiketi sokuphepha kwezempi "sebhethri ye-graphene". Kufanele ivumele ukushaja okuphindwe kabili kwamandla anamuhla: lapho namuhla inani eliphakeme lentuthuko emkhakheni kagesi liyi-3-3,5 C (amandla = 3-3,5 x umthamo webhethri), ibhethri ye-graphene emotweni ye-GAC kuthiwa vumela ukusetshenziswa 6C.
Amabhethri e-graphene - angasinika ini?
Uhlu lokuqukethwe
- Amabhethri e-graphene - angasinika ini?
- I-GAC Aion V - yini esiyaziyo
Khumbula: kumabhethri e-lithium-ion yakudala ane-electrolyte ewuketshezi, ama-anode ngokuvamile enziwa ngekhabhoni noma nge-carbon efakwe i-silicon. Ama-cathode, wona, angenziwa kusuka ku-lithium-nickel-manganese-cobalt (NCM) noma i-lithium-nickel-cobalt-aluminium (NCA). Ngesikhathi sokusebenza kwebhethri, ama-ion e-lithium ahamba phakathi kwama-electrode amabili, enikela noma emukela ama-electron. Ingena kuphi i-graphene kukho konke lokhu?
Nokho, lapho ilayishwe ngamandla amakhulu, ama-athomu e-lithium angenza ama-protrusions abizwa ngokuthi ama-dendrites. Ukuze sizivimbe, singashintsha i-electrolyte ewuketshezi ibe eqinile amathebhu angeke angene ngayo - lena yindlela esebenza ngayo kumabhethri wesimo esiqinile (i-electrolyte eqinile). Singakwazi futhi ukushiya i-electrolyte ewuketshezi, kodwa bopha i-cathode ngento enamandla amakhulu kakhulu futhi ngesikhathi esifanayo ikwazi ukungena kuma-ion.
Futhi lapha i-graphene iza ukusiza - cishe ishidi elilodwa-dimensional lama-athomu ekhabhoni ahlanganisiwe:
I-GAC Aion V - yini esiyaziyo
Manje ake sidlulele kusimemezelo se-GAC. Umkhiqizi wase-China okwamanje uhlola amabhethri e-graphene kumodeli ye-Aion V e-Mohe, e-China. Ngokusobala, wawatholela isitifiketi sokuphepha sezempi, cishe esasiwavumela ukuba asetshenziswe ezimotweni zikagesi. Ukuminyana kwamandla amabhethri e-graphene kufanele kube njalo 0,28 kWh / kg, okuhlinzekwa ngamaseli e-NCM athuthukile - akukho mpumelelo lapha (umthombo).
Impumelelo encane ubude bempilo. Imijikelezo eyizinkulungwane eziyi-1,6 sebenzisa. Akwaziwa kahle ukuthi yimiphi imijikelezo eshiwo, kodwa uma kungu-1 C (ukushaja/ukukhulula ngamandla alingana nomthamo webhethri), umphumela muhle kakhulu. Izinga lemboni yimijikelezo engu-500-1.
Ilukuluku elikhulu kunawo wonke amandla okushaja aphezulu... Kufanele kube njalo I-6 C, i.e. ibhethri elinamandla okuthi, 64 kWh - njengaku-Kia e-Niro - singashaja ngamandla amakhulu angu-384 kW. I-Tesla Model 3 enebhethri engu-74 kWh ingasheshisa ifinyelele ku-444 kW! Kusho ukuthi ngemva kwemizuzu emi-5 ishaja imoto izoqedwa hhayi ngaphansi kwamakhilomitha angu-170 webanga langempela (200 WLTP amayunithi).
Ibhethri le-graphene elisetshenziswe ku-GAC Aion V kungenzeka ukuthi amaphesenti angu-5-8 kuphela abiza kakhulu kunebhethri ye-lithium-ion evamile... Ukukhiqizwa kwe-serial yemoto ngamabhethri amasha kufanele kuqale ngoSepthemba 2021.

Inothi lomhleli www.elektrowoz.pl: Ukusetshenziswa okwethulwe kwegraphene kuseli ye-lithium-ion kungenye yezinhlelo zokusebenza ezingenzeka. Ucwaningo lweminyaka yakamuva lubonisa ukuthi lobu buchwepheshe buhamba phambili kakhulu, ngakho-ke silindele ukuthi i-GAC ihambe ngomzila we-graphene-NMC. Nokho, umkhiqizi wemoto akayivezi imininingwane, ngakho incazelo engenhla kufanele ibhekwe njengokuqagela.
