New Sodium Intercalation Cathode Prepared by Sodiation of Delithiated Host LiNi_1/3Mn_1/3Co_1/3O₂

Figure 1

Scheme of the electrochemical ion-exchange process to prepare a new sodium insertion compound from a lithium insertion compound. Lithium-ions extracted from LiNMC crystal structure during charging in Li-half-cell then sodium-ions intercalated to the structure during discharging in Na-half-cell.
