Cathode Electrolyte Interphase Formation and Electrolyte Oxidation Mechanism for Ni-Rich Cathode Materials

The Journal of Physical Chemistry C, 2020
Herein, we investigate the formation of a cathode electrolyte interphase (CEI) by electrolyte oxidation on a LiNixM1–xO2 (x > 0.5; M, transition metal) layered oxide (Ni-rich) cathode and compare t...

Thiophene-initiated polymeric artificial cathode-electrolyte interface for Ni-rich cathode material

Electrochimica Acta, 2018
Abstract Ni-rich layered oxide (Ni-rich NCM) is a promising advanced cathode material for lithium-ion batteries (LIBs) because of its high specific capacity. However, the high Ni content in the layered structures is associated with poor surface stability, which in turn accelerates the capacity fading of the cell.

Surface Reconstruction Reduces Internal Stress of Ni‐Rich Cathode Particles

Small
AbstractHigh‐voltage Ni‐rich layered cathode materials are undoubtedly a powerful driving force for high‐energy density lithium batteries. However, residual lithium impurities on the surface of Ni‐rich materials can cause more severe side reactions under high‐voltage, leading to rapid decay.
