Scientists have figured out how to turn Earth’s most abundant mineral into zero-waste battery metals. The most abundant mineral in earth’s crust is something called olivine: pretty in the gemstone peridot, but otherwise pretty useless. Now, New Zealand engineers have figured out how to dissolve olivine to yield silica (50%), magnesium (40%) and nickel-manganese-cobalt hydroxide (10%) for lithium-ion cathodes, leaving only brine.
