Recent advances in synthesis and modification strategies for lithium-ion battery ternary cathodes

Lithium-ion rechargeable batteries are regarded as the most favorable technology in the field of energy storage due to their high energy density with the global development and usage of new energy sources. New energy vehicles have developed from small and medium-sized electric devices, like digital electronics, to large-sized electric devices, new energy vehicles, its application field has developed. Future lithium-ion battery cathode materials may find the ternary cathode material (LiNi1-x-yCoxMnyO2) to be among the best options because of its high specific capacity, affordability, and environmental friendliness. Unfortunately, commercial implementation of this technology in the field of energy storage is impeded by its significant lithium-nickel mixed discharge and quick capacity degradation. This paper addresses the ion doping, surface coating, and production of ternary cathode materials for lithiumion batteries. A summary of the structural features and discharge performance was provided. Comprehensive analysis is also conducted on the benefits and drawbacks of various coating techniques as well as the impact of doping sites on the electrochemical characteristics of ternary cathode materials. Ultimately, realistic solutions and prospects for the industry are suggested in light of the inadequacies of ternary cathode materials in terms of preparation, ion doping, surface coating, etc.
