"Nickel-Manganese-Cobalt (NMC) batteries favoured by most vehicle makers contain around 20% cobalt. Tesla is a proponent of nickel-cobalt-aluminium (NCA) technology which requires less than a third the amount of cobalt."
"Musk said on Wednesday the cobalt content of its NCA cathode chemistry “is already lower than next-generation cathodes that will be made by other cell producers with a nickel-manganese-cobalt ratio of 8:1:1″."
