Kinetic stabilization of a topotactically transformed texture morphology via doping in Ni-rich lithium layered oxides

Chul-Ho Jung et al.

Summary: In this study, the role of phosphorus (P) or boron (B) doping in the development of a radially aligned textured microstructure during the synthesis of LiNi0.92Co0.04Mn0.04O2 layered oxides was investigated. It was found that the textured microstructure in P- or B-doped Ni-rich layered oxides is inherited from the hydroxide precursor morphology, and the P or B doping produces a lithium-containing amorphous oxide layer on the surface of primary particles, which delays the morphological transformation and retains the textured morphology.

Unraveling the Intricacies of Residual Lithium in High-Ni Cathodes for Lithium-Ion Batteries

Youngjin Kim et al.

Summary: High-nickel layered oxide cathodes face problems with residual lithium causing slurry gelation and gas evolution. A study showed that Li2CO3 impurity in lithium raw materials increases residual lithium in high-Ni cathodes, while LiOH formed during analyte preparation exacerbates LiOH content in residual lithium. A dry cobalt hydroxide coating on high-Ni cathodes effectively reduces residual lithium content and forms a Co-rich layer that suppresses Li leaching in contact with water.

Boron doped Ni-rich LiNi0.85Co0.10Mn0.05O2 cathode materials studied by structural analysis, solid state NMR, computational modeling, and electrochemical performance

Susai Francis Amalraj et al.

Summary: This study focused on the improvement of LiNi0.85Co0.10Mn0.05O2 (NCM85) material by doping with B3+ cations, demonstrating improved cycling performance, lower voltage hysteresis, and reduced self-discharge. Density functional theory (DFT) models were used to analyze the electronic structure and influence of boron on the material's surface characteristics. Experimental evidence showed that boron segregation at the surface effectively reduced the surface energy and increased the oxygen binding energy, inhibiting oxygen release. Additionally, microscopy and solid-state nuclear magnetic resonance (NMR) analysis correlated capacity fade and degradation with structural changes in the NCM85 materials.
