Sigma-Aldrich LITHIUM COBALT OXIDE LITHIUM-NIOBATE CO

LiNbO₃-coated LCO is a high-performance cathode active material designed for lithium-ion batteries (LIBs), including solid-state and high-voltage batteries. As a classic layered cathode material, LiCoO₂ serves as a model system for fundamental research while also delivered a high insertion potential and high capacity. The LiNbO₃ coating significantly enhances cathode stability by protecting the electrode and electrolyte from undesired reactions. It mitigates reactions between the cathode material and electrolyte, reducing capacity fade and minimizing the release of metal ions from the LCO cathode. Additionally, the highly ionically conductive LiNbO₃ improves rate capability by reducing the space
