A generalized hydrothermal strategy for fabricating three‐dimensional (3D) battery electrodes is presented. The hydrothermal growth deposits electrochemically active nanomaterials uniformly throughout the complex 3D mesostructure of the scaffold. Ni inverse opals coated with SnO 2 nanoparticles or Co 3 O 4 nanoplatelets, and SiO 2 inverse opals coated with Fe 3 O 4 are fabricated, all of which show attractive properties including good capacity retention and C‐rate performances.
