ADELAIDE, Australia—Ivan Williams reckons he may help to interrupt China’s dominance of a key ingredient of electric-vehicle batteries. To take action, he has been accumulating wooden chips from sawmills all over the world.
At a check plant in New Zealand’s picturesque Marlborough wine area, Williams and his staff feed the wooden chips into machines that end up a type of artificial graphite. He says the engineered materials is as pure as artificial graphite constituted of fossil fuels, which is usually produced in China and might account for as a lot as half of the burden of a lithium-ion battery.
