Batrị Samsung Graphene: 0-80 pasent na nkeji 10 ma ha hụrụ ikpo ọkụ n'anya!
Na Nature, Samsung SDI ndị ọkà mmụta sayensị kesara nyocha ha na mkpụrụ ndụ batrị graphene-coated cathode (GB-NCM). Nsonaazụ na-ekwe nkwa nke ukwuu: batrị anaghị atụ egwu okpomọkụ dị elu, nwere oke nchekwa nchekwa ike dị elu ma nwee ike ịchaji ozugbo.
