An efficient hydrothermal approach is demonstrated to fabricate a series of graphene‐network‐backboned hybrid architectures such as MoS 2 /graphene and FeO x /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.
