[0002] Sodium-ion batteries are "rocking-chair batteries" that achieve charge transfer by embedding and extracting sodium ions between the positive and negative electrodes. The positive electrode materials of sodium-ion batteries usually include: layered oxides, Prussian blue, tunnel oxides, and polyanion compounds; the negative electrode materials usually include five types: carbon-based materials, titanium-based materials, alloy materials, organic compounds, and other systems. Among them, carbon-based materials have the highest technical maturity and abundant resources, and are expected to be the first to achieve industrialization. Sodium-ion batteries require a stirring device to mix and stir their negative electrode materials during production.
