Using Fungi to Recycle Li-ion Batteries

As rechargeable batteries proliferate in everything from cars to smartphones, recycling is becoming a critical issue. Now a team of researchers at the University of South Florida has found a way to use naturally occurring fungi to extract cobalt and lithium from waste batteries. The scientists presented their work at […]

Tesla Introduces Third-generation Battery Pack Technology

As is often the case with Tesla, the mainstream press has missed the true significance of the company’s latest product. Tesla’s announcement of its new P100D battery pack option focused on the quicker 0-60 time, so that’s what most media outlets wrote about. Everyone other than acceleration junkies greeted it […]
