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.

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).
