Lithium rich layered oxide: exploring structural integrity, electrochemical behavior, performance failures and enhancement strategies through doping and coating

Lithium-ion batteries, while revolutionizing energy storage, face challenges in improving cathode materials. These challenges include capacity fading, and high manufacturing costs. Researchers are addressing these issues through exploring advanced materials like lithium-rich compounds. Lithium-rich layered oxides hold significant promise as next-generation high energy density cathode materials for advanced batteries. However, their practical application is hindered by challenges such as voltage decay, capacity fade, structural instability and poor cycling stability. This study aims to bridge this knowledge gap by comprehensively investigating the crystal structure, morphology, and electrochemical performance of these materials. We delve into the impact of various modifications, including element doping and surface coating techniques on their performance. It is important to focus on a deeper understanding of the underlying mechanisms and developing advanced strategies like advanced synthesis techniques, interface engineering, and computational modeling. New compositions and synthesis methods should also be used to improve energy density and cycling stability of lithium rich cathodes. In addition, challenges like compatibility with electrolytes and economic viability should be addressed to unlock their full potential for next-generation lithium-rich layered oxides battery technologies in diverse applications, ranging from electric vehicles and portable electronics to grid-scale energy storage systems.
