Recently we demonstrated that symmetric, all Au@δ-MnO2 core@shell nanowire capacitors can achieve cycle stability to 100 000 cycles and beyond in a poly(methyl methacrylate) (PMMA) gel electrolyte. Here we examine the limits of the PMMA gel to confe

We demonstrate reversible cycle stability for up to 200 000 cycles with 94–96% average Coulombic efficiency for symmetrical δ-MnO2 nanowire capacitors operating across a 1.2 V voltage window in a poly(methyl methacrylate) (PMMA) gel electrolyte. T

Nanowire electrodes for batteries and super-capacitors can produce superior power relative to films of the same materials. But the Achilles Heel of nanowires is their susceptibility to degradation and failure. This is particularly true for materials
