The Electrochemical Reaction Mechanism of Tin Phosphide with Sodium
(The Electrochemical Society, 2016-04-08)
The sodiation mechanism of Sn4P3 was studied by ex-situ X-ray diffraction and Mössbauer effect spectroscopy. These results show that Sn4P3 is initially amorphized during sodiation, and suggest that upon further sodiation ...
