The Role of Cobalt and Manganese for the Safety of Ni-Rich NMC Cathode

ECS Meeting Abstracts, 2021
The intrinsic poor thermal stability of layered LiNi x Co y Mn1–x–y O2 (NCM) cathodes and the exothermic side reactions triggered by the associated oxygen release are the main safety threats for their large-scale implantation.

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.
