Mutsva kumota ine graphene bhatiri? GAC: Ehe, muAion V tiri kuiyedza izvozvi. Kuchaja 6 C!
IChinese GAC inoti yawana chitupa chekuchengetedza mauto che "graphene bhatiri". Inofanirwa kubvumira kuchaja nekaviri simba remazuva ano: apo nhasi iyo yepamusoro yekufambira mberi mumunda wemagetsi iri 3-3,5 C (simba = 3-3,5 x bhatiri huwandu), zvinonzi iyo graphene bhatiri muGAC. motokari inobvumira kushandisa 6C.
Graphene mabhatiri - chii chavanogona kutipa?

- Graphene mabhatiri - chii chavanogona kutipa?
- GAC Aion V - chii chatinoziva
Rangarira: mumabhatiri e-lithium-ion echinyakare ane electrolyte yemvura, anodesi anowanzo kugadzirwa nekabhoni kana kabhoni yakadhindwa nesilicon. Iyo cathodes, zvakare, inogona kugadzirwa kubva lithium-nickel-manganese-cobalt (NCM) kana lithium-nickel-cobalt-aluminium (NCA). Panguva yekushanda kwebhatiri, lithium ions inofamba pakati pema electrode maviri, ichipa kana kugamuchira maerekitironi. graphene inopinda papi mune zvese izvi?
Zvakanaka, kana yakatakurwa nesimba repamusoro, maatomu elithium anogona kugadzira maprotrusions anonzi madendrites. Kuti tivavhare, tinogona kushandura iyo electrolyte yemvura kuita yakasimba iyo ma tabo asingapindire - aya ndiwo mabatiro aanoita mumabhatiri akasimba (solid electrolyte). Tinogonawo kusiya mvura electrolyte, asi kuputira cathode nechinhu chine simba rakanyanya kusimba uye panguva imwechete inopindira kune ions.
Uye pano graphene inouya kuzonunura - rinenge rimwechete-dimensional pepa reakasungwa kabhoni maatomu:
GAC Aion V - chii chatinoziva
Zvino ngatienderere mberi kune GAC declaration. Mugadziri weChinese parizvino ari kuyedza mabhatiri egraphene muAion V modhi muMohe, China. Sezviri pachena, akagamuchira gwaro redziviriro yehondo nokuda kwavo, zvichida richivabvumira kushandiswa mumotokari dzemagetsi. Simba density yemabhatiri egraphene inofanira kunge iri 0,28 kWh / kg, iyo yepamusoro NCM maseru inopa - hapana budiriro pano (mabviro).
Kubudirira kudiki kunotarisirwa kurarama. 1,6 zviuru zvitenderera tsika. Hazvinyatsozivikanwi kuti ndeapi mapeji anotaurwa, asi kana iri 1 C (kuchaja / kuburitsa nesimba rakaenzana nekugona kwebhatiri), mhedzisiro yacho yakanaka kwazvo. Iyo indasitiri chiyero ndeye 500-1 kutenderera.
Kuda kuziva kukuru yakanyanya kuchaja simba... Zvinofanira kudaro 6 C, i.e. bhatiri rine simba rekuti, 64 kWh - sezvakaita Kia e-Niro - tinogona kuchaja nesimba guru re 384 kW. Tesla Model 3 ine 74 kWh bhatiri inogona kukurumidza kusvika 444 kW! Zvinoreva kuti mushure memaminitsi mashanu kuchaja motokari ichapedzwa kwete asingasviki 170 makiromita echokwadi renji (200 WLTP zvikamu).
Iyo graphene bhatiri inoshandiswa muGAC Aion V ingangove chete 5-8 muzana inodhura kupfuura yakajairwa lithium-ion bhatiri... Kugadzirwa kweseri kwemota nemabhatiri matsva kunofanirwa kutanga munaGunyana 2021.

Chinyorwa chekunyora www.elektrowoz.pl: Kuiswa kwegraphene musero relithium-ion ingori imwe yemashandisirwo anobvira. Tsvagiridzo mumakore achangopfuura inoratidza kuti iyi tekinoroji ndiyo yakanyanya kufambira mberi, saka isu tinotarisira kuti GAC iende nenzira yegraphene-NMC. Nekudaro, mugadziri wemotokari haaburitse ruzivo, saka tsananguro iri pamusoro inofanira kutorwa sekufungidzira.
