Regulating thermal expansion in the iron sulfide anode for stable sodium storage
A Ho<sub>2</sub>Fe<sub>17</sub> alloy, with thermal volume contraction and excellent electronic/thermal conductivity, is introduced into an Fe<sub>7</sub>S<sub>8</sub>-based anode material. The decreased internal temperature and improved structural stability of the battery result in an enhanced sodium storage capacity and long-term cycling stability.
