Improved Synthetic Routes to Layered NaxCoO2Oxides

Abstract
Improved synthetic routes to fourNaxCoO2 (0.52 ≤ x ≤ 1) oxides of varying compositions and structures are presented. A combination of ceramic techniques and oxidative deintercalation reactions were used to access this series. Comparisons are made to previously reported preparative methods and differences in unit cell parameters discussed.
