摘要：

A hybrid network CuS monolith cathode, consisting of the microporous network formed by CuS sheets and particles on three-dimensional macroporous monolith Cu foam, is synthesized by a facile in situ melt-diffusion strategy without binder for Li-ion batteries. The cathode shows an abnormal capacity of 185.1 and 468.3 mAh g(-1) CuS for the first and 100th cycle at a current rate of 0.2 C(1 C = 560 mA g(-1)), respectively. And it could recover 83.9% of the capacity after cycled at various current rates, demonstrating an excellent rate capability which outperforms many other currently available CuS cathodes.
