Three‐dimensional (3 D) nanoporous SnO 2 –M x O y (M=Fe, Co, Ni, Cu, etc.) hybrid networks possess unique compositional and structural features that are beneficial to lithium storage and are thus anticipated to meet the performance requirements of advanced lithium‐ion batteries for transportation and stationary energy storage. Herein, a facile, scalable, and versatile cyanogel‐derived method for the construction of 3 D nanoporous SnO 2 –M x O y hybrid networks was developed for the first time. The formation of 3 D nanoporous SnO 2 –NiO, SnO 2 –α‐Fe 2 O 3 , and SnO 2 –NiO–Co 3 O 4 hybrid networks was illustrated by using Sn–M cyanogels as precursors. Moreover, the anodic performance of the 3 D nanoporous SnO 2 –NiO hybrid network was examined to demonstrate proof of concept. After coating with polypyrrole‐derived carbon, the SnO 2 –NiO@C hybrid network exhibited superior lithium‐storage capabilities in terms of specific capacity, cycling stability, and rate capability.
