The global demand for high-energy lithium-ion batteries is rising, driven by the push for electric vehicles and renewable energy storage. Lithium-rich layered oxides (LRMO) stand out because of their high theoretical capacity and cost advantages. Yet despite their promise, they face critical setbacks: oxygen release at high voltages, severe structural transformations, and interfacial corrosion triggered by electrolyte decomposition. These processes not only erode the electrode surface but also lead to transition metal loss and voltage decay. Many surface coating strategies have been explored, yet they often fall short by impeding ion transport or peeling away during cycling. Due to these challenges, there is an urgent need to engineer more effective surface protections for lithium-rich cathodes.
