摘要：

In this work, we present a three-dimensional elastic carbon foam as a current collector and freestanding electrode for Li-S batteries. A sulfur content of approximately 43.93% which was based on the weight of cathode was achieved. The non-additive S cathode with good elasticity shows a first discharge specific capacity of 893 mA h g(-1) and a specific capacity of 544mA h g(-1) after 30 cycles at moderate rates. A coulombic efficiency of 98% over 100 cycles is achieved.
