Battery science, charging systems, automotive technology and the innovations reshaping the future of mobility.
Battery chemistry, materials, manufacturing, energy storage and the technologies powering electric mobility.
Lithium sits at the heart of nearly every modern EV battery, but where does it come from? We trace lithium from hard-rock mines and salt-flat brines through refining and battery production, examining its environmental and human impact along the way.
Nickel helps give many EV batteries their high energy density, but where does it come from? We trace nickel from mines in the Philippines and elsewhere through refining and battery production, examining its environmental and human impact along the way
