Strain-retardant coherent perovskite phase stabilized Ni-rich cathode

Nature, 2022
The use of state-of-the-art Ni-rich layered oxides (LiNixCoyMn1-x-yO2, x > 0.5) as the cathode material for lithium-ion batteries can push the energy and power density to a higher level than is currently available1,2. However, volume variation associated with anisotropic lattice strain and stress that is being developed during lithium (de)intercalation

Developments in Surface/Interface Engineering of Ni‐Rich Layered Cathode Materials

The Chemical Record, 2022
AbstractNi‐rich layered cathodes with high energy densities reveal an enormous potential for lithium‐ion batteries (LIBs), however, their poor stability and reliability have inhibited their application. To ensure their stability over extensive cycles at high voltage, surface/interface modifications are necessary to minimize the adverse reactions at the

Revealing the Subzero‐Temperature Electrochemical Kinetics Behaviors in Ni‐Rich Cathode

Small, 2023
AbstractThe sluggish kinetics in Ni‐rich cathodes at subzero temperatures causes decreased specific capacity and poor rate capability, resulting in slow and unstable charge storage. So far, the driving force of this phenomenon remains a mystery. Herein, with the help of in‐situ X‐ray diffraction and time of flight secondary ion mass spectrometry ...

Calcium‐ and sulfate‐functionalized artificial cathode–electrolyte interphases of Ni‐rich cathode materials

Rare Metals, 2021
Abstract Ni‐rich lithium nickel–cobalt‐manganese oxides (NCM) are considered the most promising cathode materials for lithium‐ion batteries (LIBs); however, relatively poor cycling performance is a bottleneck preventing their widespread use in energy systems.

Reversible planar gliding and microcracking in a single-crystalline Ni-rich cathode

Science, 2020
Cracking the problem of cracking cathodes Polycrystalline cathode materials that contain a combination of nickel, manganese, and cobalt have been used for advanced lithium batteries. These materials fracture at high voltage, which increases surface area and leads to more side reactions and shorter cycle life.

Improvement of Electrochemical Properties of Ni-Rich Cathode Material by Polypyrrole Coating

Journal of Nanoscience and Nanotechnology, 2016
In this study, we attempted a nanosized coating layer of commercial polypyrrole (PPy) on LiNi0.6Co0.1Mn0.3O2 (HNCM) cathode material to overcome the side reactions with electrolyte and a decrease in the capacity of the inert coating layer. The coating method using commercial PPy is very simple.
