Heterogeneous TiO(2)@Nb(2)O(5) composite as a high-performance anode for lithium-ion batteries

Heterogeneous TiO(2)@Nb(2)O(5) composites, in which TiO(2) nanoparticles were evenly embedded on ultrathin Nb(2)O(5) nanosheets, were used as anode materials for LIBs and demonstrated high capacities and excellent rate capability. For instance, this material displayed large capacities of 166.3 and 1...

Sumario:Heterogeneous TiO(2)@Nb(2)O(5) composites, in which TiO(2) nanoparticles were evenly embedded on ultrathin Nb(2)O(5) nanosheets, were used as anode materials for LIBs and demonstrated high capacities and excellent rate capability. For instance, this material displayed large capacities of 166.3 and 129.1 mA h g(−1) at current densities of 1 A g(−1) after 100 cycles and 5 A g(−1) after 300 cycles, respectively.
