New cobalt-free high-voltage spinel cathode material with high areal capacity

Green Car Congress

Advancing cathode materials with both high energy density and low cost have always been the main objective of battery material research. It should be noted, the cost and sustainability of lithium-ion batteries are not only limited by the production of Co and Ni but also potentially limited by the lithium element itself. …

Argonne, PNNL researchers develop new cobalt-free cathode for high-energy Li-ion cells

Green Car Congress

O 2 cathode with a predominant, partially-disordered lithiated-spinel structure was prepared by a low-temperature (LT) synthesis. In an open-access paper in the RSC journal Chemical Communications , the team reports that Li/LT-LiMn 0.5 Boyu Shi, Jihyeon Gim, Linze Li, Chongmin Wang, Anh Vu, Jason Croy, Michael M. V and ~4.6

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.
