A Review on Element Doping in Li-Rich Cathode Materials for Lithium-Ion Batteries
With the growing demand for clean energy, lithium-ion batteries (LIBs) have become essential in applications like electric vehicles due to their high energy density and efficiency. However, conventional cathode materials such as LiCoO₂ and LiFePO₄ are limited by relatively low specific capacities. T...

| description | With the growing demand for clean energy, lithium-ion batteries (LIBs) have become essential in applications like electric vehicles due to their high energy density and efficiency. However, conventional cathode materials such as LiCoO₂ and LiFePO₄ are limited by relatively low specific capacities. To address this, Li-rich Mn-based cathode materials (LRMs) have been proposed as promising alternatives, offering greater specific capacity. Despite their potential, LRMs suffer from challenges like voltage decay, poor rate performance, and safety problems during cycling. This review discusses the use of element doping, such as the introduction of Al, Cr, and Ti, to improve the structural stability and electrochemical properties of LRMs. While significant progress has been made in enhancing capacity and cycle life, issues like voltage fade and long-term stability persist. Future research should focus on optimizing doping strategies, enhancing structural integrity, and reducing costs to facilitate the widespread use of LRMs in energy storage and electric vehicle systems. |
