Abstract

Electronic and ionic conductivity of pseudocapacitive SnO2 can be dramatically improved by a hierarchically oxide/metal nanoporous structure. The hierarchical nanoporosity gives rise to an exceptionally high volumetric power density of 257 W cm-3 and excellent cycling stability along with high volumetric energy density and ultrafast rate capability in both aqueous and nonaqueous electrolytes.
