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 absence of a slag allows a nearly 100% recovery of Co, Ni, and Mn in the formed alloy and a nearly 100% recovery of lithium in the flue dust.

U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

Researchers from the Cockrell School of Engineering at The University of Texas at Austin have developed a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways. More nickel in a battery means it can store more energy.

Argonne team develops new approach to cobalt-free Li-ion cathodes

Green Car Congress

Researchers at Argonne National Laboratory have developed a new approach to cobalt-free Li-ion cathodes that avoids some of the problems with other low-cobalt cathode approaches. Ni is in between Co and Mn in all these criteria. Ni, Mn, Co; NMC) oxides with low Mn and Co contents, e.g., NMC-811.
