摘要： The present invention provides an electrode that can be used for a sodium secondary battery having a larger discharge capacity when charging and discharging are performed repeatedly than that of the prior art. This sodium secondary battery electrode contains tin (Sn) powder as an electrode active material. The electrode, particularly, further contains one or more electrode-forming agents selected from the group consisting of poly(vinylidene fluoride) (PVDF), poly(acrylic acid) (PAA), poly(sodium acrylate) (PAANa), and carboxymethylcellulose (CMC), thereby making it possible to provide a sodium secondary battery having even greater electrode performance.
