Abstract
Na2Mo2O7 was synthesized by solid-state reaction route and explored as possible anode material for sodium ion battery for the first time. The electrochemical reaction with sodium involves an initial insertion of 0.33 Na/f.u into the lattice followed by conversion reaction. The material shows good reversibility and high rate capability. A reversible capacity of ∼200 mAh g−1 is obtained after 50 cycles. The presence of lattice sodium facilitates reversible sodiation/de-sodiation.
