This invention relates to a rapid drying method, apparatus, and sodium-ion battery for Prussian blue analogue sodium-ion battery electrodes, belonging to the field of sodium-ion battery manufacturing technology. The rapid drying method includes the following steps: S1: Preparing the wet electrode sheet and feeding it into a drying chamber for drying; S2: Transferring it to an internally heated dehydration section for gradient temperature dehydration; S3: Transferring it to an instantaneous high-temperature dehydration section for instantaneous high-temperature dehydration; S4: Transferring it to a heat-preserving dehydration section for further deep dehydration; S5: Cooling the electrode sheet after step S4 to obtain a dried electrode sheet. This drying method has the advantages of being rapid and low-cost, and can minimize structural damage to the Prussian blue analogue material.
