Descripción
Sumario:Bi(2)Se(3) was studied as a novel sodium-ion battery anode material because of its high theoretical capacity and high intrinsic conductivity. Integrated with carbon, Bi(2)Se(3)/C composite shows excellent cyclic performance and rate capability. For instance, the Bi(2)Se(3)/C anode delivers an initial capacity of 527 mAh g(−1) at 0.1 A g(−1) and maintains 89% of this capacity over 100 cycles. The phase change and sodium storage mechanism are also carefully investigated.
