Answer:
No, sodium cobalt oxide would not work as the electrode material
Explanation:
Sodium is a much larger cation than lithium. Remember that ion size is a very important consideration when developing a battery. The ions to be substituted must be nearly of the same size if one ion is to replace the other in a crystal.
Since sodium ions are larger than lithium ions, sodium cobalt oxide would not work as the electrode material in Lithium ion batteries.
