Abstract

An efficient hydrothermal approach is demonstrated to fabricate a series of graphene-network-backboned hybrid architectures such as MoS2/graphene and FeOx/graphene, showing high specific surface area, porous structure, and continuous graphene networks. Such unique architectures exhibit a high reversible capacity (about 1100 mA h g−1) for lithium ion batteries. High-rate capabilities of full charge to discharge in 25–45 s with a long cycle life (1500 cycles) are achieved at different rates.
