摘要：

We combined the good cycle ability and rate performance of carbon-nanostructured hollow spheres with the high specific capacity at first discharge of nitrogen-doped carbon aerogels. Beneficial contributions of each constituent material, i.e., N-doped carbogel and carbon hollow spheres, led to a promising synergistic effect. A high specific capacity of more than 700 mA h g(-1) was reached with a limited fading over 25 cycles.
