Libetri tsa Samsung Graphene: liperesente tse 0-80 ka metsotso e 10 'me li rata mofuthu!
Nature, bo-rasaense ba Samsung SDI ba arolelane lipatlisiso tsa bona ka lisele tsa betri tsa graphene-coated cathode (GB-NCM). Liphetho li ts'episa haholo: libeteri ha li tšabe mocheso o phahameng, li na le matla a mangata a polokelo ea matla 'me li ka nchafatsoa hang-hang.

Libetri tsa Graphene Samsung SDI GB-NCM
Libetri tsa Samsung SDI graphene ha e le hantle ke libeteri tsa lithium-ion tsa khale tsa Nickel Cobalt Manganese Electrode (NCM) tse nang le ntlafatso e le 'ngoe: graphene spheres holim'a metsi. Meaho ena e bontšitsoe haufi-ufi ka ho le letona:
Ka graphene Libetri tsa Samsung SDI li na le matla a matla a 800 Wh ka litha e le nngwe (Wh / L).e leng litšenyehelo tse hakanyetsoang tsa lisele tse latelang tsa NCM 811, tse lokelang ho fihla 'marakeng ka mor'a 2021.
Ka nako e ts'oanang, libeteri li boloka 78,6% ea matla a tsona ka mor'a lipotoloho tse 500 tsa ho tjhaja / ho ntša mocheso pakeng tsa 0 le 60 degrees Celsius. Ha e e-so fele: e ntlafalitsoe ka lifaha tsa graphene libeteri ka ho hlaka li rata mofuthu!
Ka likhato tse 60, li na le matla a phahameng a polokelo ea matla, ke hore, li na le bokhoni bo eketsehileng: 444 li-watt-hora ka k’hilograma ea sele ka likhato tse 60 ha li bapisoa le lihora tse 370 tsa watt ka kilogram ka likhato tse 25!
