Co-Precipitation of Ni-Rich Me(OH)2 Precursors for High Performance LiNixMnyCo1-x-yO2 Cathodes: A Review
The LiNixCoyMn1-x-yO2 (NCM) cathode materials have emerged as critical components in lithium-ion batteries due to their high energy and power densities. The co-precipitation method is widely used in laboratory and industry settings to optimize the crystallinity, grain morphology, particle size, and sphericity of precursor materials, directly affecting NCM battery performance. This review addresses the nucleation mechanism and the thermodynamic and kinetic reaction processes of co-precipitation. The comprehensive effects of key parameters on precursor physicochemical properties are also systematically interpreted. Notably, precursor characterization and physicochemical properties, including impurity levels and tolerance limits relevant to production, are highlighted. Finally, optimization strategies for developing high-quality precursor materials toward commercialization are proposed. This systematic review provides a deeper understanding of precursor optimization and advances relevant theories for the development of NCM cathode materials.
期刊介绍：
Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
