Electronics, power tools, cell phones, laptops. Solid-state, lithium-sulfur, sodium batteries—would all of these still be using graphite in the anode? There’s also pre-lithiation of the anode which is kind of preloading it with lithium ions. How do they differ, and why do you need a blend of the different kinds?

Volvo’s CEO Jim Rowan stated earlier this year that increasing the computing power in EVs will be harder and more altering of the automotive industry than switching from ICE vehicles to EVs. Mining the raw materials, of course, assumes that there is sufficient refining capability to process them, which outside of China , is limited.
