Li-rich Cathode Active Material Powder

Overview

Li-rich manganese-based layered oxides are next-generation lithium-ion battery cathode active materials designed for high specific capacity through a hybrid redox mechanism. In addition to conventional transition-metal redox (Ni/Co/Mn), Li-rich compositions can access extra capacity associated with oxygen redox activity within the layered lattice, helping researchers explore higher-energy cathode chemistries.

Working mechanism

During charge, lithium deintercalates from the layered oxide structure. At higher states of charge, capacity can increasingly involve oxygen redox contributions alongside transition-metal oxidation. During discharge, lithium reinserts and the redox states partially reverse. This chemistry is widely studied for its high capacity potential, while also requiring careful control of voltage window, electrolyte stability, and cycling protocols to manage voltage fade and interfacial reactivity.
