Advanced Ternary Cathode Materials for High-Performance Lithium-Ion Batteries

The global shift from fuel-powered vehicles to electric vehicles (EVs) is accelerating, driven by the need to achieve zero emissions. As a cornerstone of this transformation, the development of advanced battery technology is crucial. Among the various components, ternary cathode materials are emerging as a dominant force in powering next-generation EVs. This paper explores the factors negatively impacting the cycling stability and electrochemical performance of nickel-rich ternary cathode materials. In response, it proposes several modification strategies, including ion doping, single-crystal structuring, and surface coating. By exploring these individual approaches, the paper highlights the need for future research to focus on integrating multiple modification techniques. The primary objective is to create batteries with high energy density, superior cycling performance, excellent electrochemical characteristics, and enhanced safety—paving the way for breakthroughs in this rapidly evolving field.
