By collecting and analyzing relevant literature results, we demonstrate that the nanostructuring
of polypyrrole (PPy) electrodes is a crucial strategy to achieve high performance and stability
in energy devices such as fuel cells, lithium batteries and supercapacitors. In this critic and comprehensive
review, we focus the attention on the electrochemical methods for deposition of PPy, nanostructures
and potential applications, by analyzing the effect of different physico-chemical parameters,
electro-oxidative conditions including template-based or template-free depositions and cathodic polymerization.
Diverse interfaces and morphologies of polymer nanodeposits are also discussed.
