Amabhethri e-Samsung Graphene: amaphesenti angu-0-80 emizuzwini eyi-10 futhi athanda ukufudumala!
Emvelweni, ososayensi kwa-Samsung SDI babelane ngocwaningo lwabo ngamaseli ebhethri e-graphene-coated cathode (GB-NCM). Imiphumela iyethembisa kakhulu: amabhethri awakwesabi amazinga okushisa aphakeme, anomthamo omkhulu kakhulu wokugcina amandla futhi angashajwa kabusha ngokushesha.
Uhlu lokuqukethwe
- Kungani izimoto zikagesi zishaja kancane kangaka?
- Amabhethri e-graphene Samsung SDI GB-NCM
Enkulumweni yakamuva kwabezindaba mayelana nokutholwa kukaShell kwe-IONITY, abakwaShell bathembise ukufaka amakhulu ambalwa amashaja e-kilowatt (kW) DC kanye ne-DC. noma kunjalo Ishaja iyingxenye kuphela yendida. Imoto kufanele imunce la mandla - futhi yilapho izitebhisi ziqala khona..
Ngaphezu kuka-150-200 kW, amabhethri ashisa ngokushesha kangangokuthi amasistimu okupholisa awakwazi ukuwapholisa. Lokhu kuholela ekwandeni kwenani lemicu ye-lithium ngaphakathi kanye nokuwohloka ngokushesha kwamaseli, okunciphisa kakhulu umthamo webhethri.

Ngakho-ke, izimoto zanamuhla zikhokhiswa i-direct current (DC) enamandla angekho ngaphezu kwe-120 kW (maduze: 150 kW) ukuze ingalimazi ibhethri. Yingakho ososayensi besebenza ngamabhethri akwazi ukushaja amandla aphezulu kanye namazinga okushisa.
Amabhethri e-graphene Samsung SDI GB-NCM
Amabhethri e-Samsung SDI graphene empeleni angamabhethri e-lithium-ion yakudala ye-Nickel Cobalt Manganese Electrode (NCM) anesithuthukisi esisodwa: ama-graphene sphere ngaphezulu. Lezi zakhiwo ziboniswa eduze kwesokudla:
Nge-graphene Amabhethri e-Samsung SDI ane-energy density engu-800 Wh ilitha (Wh / L).okuyizindleko ezilinganiselwe zamaseli esizukulwane esilandelayo se-NCM 811, okufanele angene emakethe ngemva kuka-2021.
Ngesikhathi esifanayo, amabhethri agcina u-78,6% womthamo wawo ngemuva kwemijikelezo engu-500 yokushaja / yokukhipha emazingeni okushisa aphakathi kuka-0 no-60 degrees Celsius. Akukapheli okwamanje: kuhlanganiswe ubuhlalu be-graphene amabhethri ngokucacile athanda ukufudumala!
Kuma-degree angu-60, anomthamo omkhulu wokugcina amandla, okungukuthi, anamandla kakhulu: 444 amahora wama-watt ngekhilogremu ngayinye yeseli ngama-degree angu-60 ngokumelene nama-watt-amahora angu-370 ngekhilogremu ngama-degree angu-25! Ngakho ukufudumala ibhethri ngenkathi ishaja kuzozuzisa umshayeli.
Kodwa akugcini lapho: amabhethri angakwazi ukushaja amandla aphezulu. Lapho i-5 degrees Celsius, kwakungenzeka ukushaja ibhethri kusuka kumaphesenti angu-0 kuya kwangu-80 ngaphansi kwemizuzu eyi-10!
