New smelting reduction process to recover Co, Ni, Mn, and Li simultaneously from Li-ion batteries

Green Car Congress

A team from metals research institute SWERIM in Sweden reports on a smelting reduction process to recover cobalt, nickel, manganese and lithium simultaneously from spent Li-ion batteries. The presence of slag may retain some Co, Ni, Mn, and Li in the slag due to the inherent nature of the slag. —Hu et al. 2020.228936.

PNNL team develops carbon nanotube-silicon microspheres as high-performance Li-ion anodes

Green Car Congress

Silicon is an appealing anode material for Li-ion batteries because it can hold about 10 times the electrical charge per gram compared to graphite. Then we used aluminum and higher heat to convert the silicon oxide into silicon, followed by immersion in water and acid to remove by-products. —Xiaolin Li.
