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.

Nanjing researchers design new Li-rich layered cathode

Green Car Congress

Researchers at Nanjing University (China) have introduced a new layered C2/m oxide—Li 2 Ni 0.2 Compared with Li 2 MnO 3 (LMO), LNMR displays superior capacity, a more stable capacity retention rate, higher energy density and average discharge voltage. In such materials, 1/3 of the TM sites are occupied by Li phase.

New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Boyang Li of the University of Pittsburgh is co-lead author of the paper.

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.

IDTechEx comments on Volkswagen’s long-term, high-manganese cathode strategy

Green Car Congress

The options for high-manganese cathodes include LMO (lithium-manganese oxide), LNMO (lithium-nickel-manganese oxide), Li-Mn-rich (also abbreviated as LMR-NMC), and LMP (lithium manganese phosphate) or LMFP (lithium-manganese-iron phosphate). Comparison between NMC 811 and three high-manganese cathodes (LMFP, Li-Mn-rich, LNMO).
