Abstract Nanostructured transition metal oxides (NTMOs) have engrossed substantial research curiosity because of their broad diversity of applications in catalysis, solar cells, biosensors, energy storage devices, etc. Among the various NTMOs, manganese oxides and their composites were highlighted for the applications in Li-ion batteries and supercapacitors as electrode materials owing to their environmental friendly nature and various oxidation states. This review concerns the deposition, characterization, and applications of nanostructured manganese oxide thin films (NMOTFs) during the few decades. The deposition and characterization of NMOTFs are discussed. Characterization discussed here enlightens the structural and morphological studies. The focus of the application section includes Li-ion batteries and supercapacitors.

1 Introduction The origin of numerous scientific and industrial innovations of the twenty-first century is Nanotechnology. It has led to advancements in novel materials on nano-meter scale. A unique aspect of nanotechnology is the significantly increased surface-to-volume ratio of nanomaterials which opens new possibilities in surface-based science. Several physical phenomena become noticeably pronounced as the particle size decreases which comprise quantum as well as statistical mechanical effects. On the nanoscale, materials show different properties as compared to bulk form and enable inimitable applications. Most of the enthrallment with nanotechnology is on the nanoscale. A small particle with any one of the dimensions in the range 1–100 nm is considered as nanoparticle which may include nanocrystals, nanoclusters and nanopowders. Nanomaterials have become promising candidates for numerous potential applications owing to mesmerizing catalytic, magnetic and electrical properties [1–3]. Nanomaterials exhibit outstanding properties as electrode materials such as larger surface areas, * A. U. Ubale [email protected] 1
