Tesla reportedly bought patent applications from Springpower International, which has researched environmentally friendly ways to make lithium-ion batteries. The purchase comes as Tesla’s Elon Musk calls for an overhaul of the battery-making process. (TechCrunch)
Talking point: With a wave of governments and manufacturers pledging to ramp up electric-vehicle production, Tesla and others in the battery industry are being pushed to minimize waste—particularly amid growing competition to bid up limited supplies of copper, lithium, nickel, cobalt and rare-earth minerals.
