Hybrid anode materials for Li‐ion batteries are fabricated by binding SnO 2 nanocrystals (NCs) in nitrogen‐doped reduced graphene oxide (N‐RGO) sheets by means of an in situ hydrazine monohydrate vapor reduction method. The SnO 2 NCs in the obtained SnO 2 NC@N‐RGO hybrid material exhibit exceptionally high specific capacity and high rate capability. Bonds formed between graphene and SnO 2 nanocrystals limit the aggregation of in situ formed Sn nanoparticles, leading to a stable hybrid anode material with long cycle life.
