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

Researchers designs new deep eutectic solvent to recover valuable elements from spent LNCM batteries

Green Car Congress

A team from Central South University in China has developed a new type of deep eutectic solvent (DES) that can efficiently leach metal elements from spent Ni-Co-Mn lithium-ion batteries (LNCM). The leaching rates of Ni, Co, Mn, and Li can all reach 99% under the conditions of T=140°C, t=10 min and no reductant.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode.
