Key Points

  • The aim is to enhance the stability and performance of sodium layered oxide cathodes through co-doping.
  • Evaluated cathode performance at 4.2 V with cycling at 5C for 500 cycles.
  • Measured capacitive performance in coin and Ah-scale pouch cells.
  • Assessed scalability potential for kilogram production.
  • Retained 80% capacity after 500 cycles at 5C.
  • Showed excellent performance in various cell formats.
  • Demonstrated commercial promise for high-voltage O3-type cathodes.

Abstract

at 4.2 V, retains 80% after 500 cycles at 5C. Furthermore, the cathode is scalable to kilogram batches. With excellent coin and Ah-scale pouch-cell performance, it shows guidance of design and commercial promise for high-voltage O3-type cathodes.
