Squeeze in! Sodium-deficient nickel–manganese oxides exhibit a layered structure, which is flexible enough to acquire different layer stacking. Specific features of the P3-type structure for reversible and fast sodium and lithium intercalation are demonstrated; this property contributes to the design of low-cost electrodes for both sodium- and lithium-ion batteries (see figure).
