Molybdenum Improves Cathode Materials’ Performance in Li Batteries

Electric vehicle batteries-the Li-ion packs image

A study at the University of Queensland has shown that tungsten and molybdenum (Mo) can improve the electrochemical properties of the cathode materials in Li batteries. As the driving range of electric vehicles increases, more nickel is needed to increase energy density, but this also reduces cycle stability. Tungsten and Mo improve stability by enhancing structural stability and resistance of the cathode material surface layer to electrode/electrolyte side reactions.

Tungsten Improves Electrochemical Performance of Cathode Materials for Li Batteries

Thermal stability of lithium battery electrolyte image

A study conducted by researchers at the University of Queensland has shown that the specific properties of metallic materials such as tungsten (W) and molybdenum (Mo) could improve the electrochemical properties, especially the cycle stability, of cathode materials in Li batteries. Ni–Co–Mn ternary oxide materials (NCMs) and Ni–Co–Al materials (NCAs) are widely used as cathodes in lithium ions for electric vehicles. Increasing the driving range of electric vehicles necessitates a raise of the nickel content to increase the energy density, which, however, degrades the cycle stability.
