Role of Residual Li and Oxygen Vacancies in Ni-rich Cathode Materials

ACS Applied Materials & Interfaces, 2021
Residual Li and oxygen vacancies in Ni-rich cathode materials have a great influence on electrochemical performance, yet their role is still poorly understood. Herein, by simply adjusting the oxygen flow during the high-temperature sintering process, some Li2O can be carried into the exhaust gas and the contents of residual Li and oxygen vacancies in ...

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.

Sulfonate-immobilized artificial cathode electrolyte interphases layer on Ni-rich cathode

Journal of Power Sources, 2017
Abstract Although lithium nickel cobalt manganese layered oxides with a high nickel composition have gained great attention due to increased overall energy density for energy conversion/storage systems, poor interfacial stability is considered a critical bottleneck impeding its widespread adoption.

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.

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.
