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.

Proterial developed a technology that reduces CO2 emissions during Li-ion cathode material production by more than 20%

Green Car Congress

formerly Hitachi Metals, earlier post ) has developed a technology to manufacture cathode materials for lithium-ion batteries (LIBs) without the previously required process of converting nickel to nickel hydroxide(Ni(OH) 2 ) to produce a precursor that is used as the starting material for the manufacture of cathode materials.

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. —Bi et al.
