SUMMARY

  • Lithium-rich layered oxides are promising cathode materials with remarkable electrochemical performance that will revolutionize the electronics, transportation, battery, and grid energy storage industries.

  • The ion-exchange process is a soft chemical synthesis route that is used to prepare new meta-stable materials, including layered oxides, as it separates and purifies crucial metals needed for battery materials science.

  • However, the ion-exchange process lacks an aspect of control that is crucial in chemical composition and spatial distribution to maximize the number of layered oxides produced.

  • The faculty inventor has found a way to controllably synthesize LixNayTMO2  layered oxides in chemical composition and in spatial distribution via electrochemical assisted ion-exchange in a Li, Na mixture solution.

  • This novel controllable synthesis method will enlarge the layered oxides library available in battery materials and ultimately promote the development of the energy battery field.
