UC Irvine team creates long-lasting, cobalt-free, low-nickel lithium-ion batteries

Green Car Congress

In a discovery that could reduce or even eliminate the use of cobalt—which is often mined using child labor—in the batteries that power electric cars and other products, scientists at the University of California, Irvine (UCI) have developed a long-lasting alternative made with nickel. The LiNi 0.5 V vs graphite, at 1 C, 1.5 mA cm

Are EV Batteries an Environmental Hot Mess?

The Truth About Cars

A 2006 Battery Directive dealt with safe recycling and disposal of Pb-acid and Ni-Cd batteries when Li-ion batteries used in electric vehicles (EVs) and hybrids were still in their infancy. These new rules will supposedly improve Li-ion […]. appeared first on The Truth About Cars.
