These results show that Sn4P3 is initially amorphized during sodiation, and suggest that upon further sodiation both Sn and P react simultaneously with Na to form Na3P, Na0.6Sn, and Na4Sn4. Upon further sodiation, the Na-Sn phases react with Na to make Na5Sn2 and Na15Sn4. These results are consistent with the behavior of Sn4P3 in Li cells.CC BY-NC-NDArticle
