Dear Colleagues,

Several environmental issues caused by consumption of fossil fuels for generating electricity and power engines lead an urgent need to develop efficient, clean and renewable energy sources to maintain a sustainable economic development. At present rates of use, oil and gas reserves could last for 50 years and coal for 150 years. In practice, concerns about climate change will mean that most of these fossil fuel reserves will have to remain the ground. This calls for the hurrying development of green energy productions, such as tidal energy, wind energy and solar energy using renewable sources. However, this green energy productions completely depends on weather, ideal wind sites are often in remote locations, the solar energy can still be collected during cloudy and rainy days but the efficiency of the solar system drops compared to normal conditions. Due to many more dis-advantages with green energy production such as unstable in nature and sporadic, suggesting that energy storage devices must be co-existed to keep them in reserve and use them in demands. 

To date, various nanostructured electrode materials such as transition metal oxides or hydroxides, grapheme and conductive polymer materials have attracted a wide range of interest as an electrode material but unfortunately their outcome values are very low. In this new research topic, the main idea is to explore the efficient electrode material for energy storage devices and energy conversion and study the critical assessment of their constituent including the flexible substrate, electrolytes, materials, and device stability and fabrication. The main goal of this special issue is to provide a skilled platform for researchers working on energy storage and energy generation applications, where they can share their new outcome values, methods, materials, challenges, and perspectives of the energy storage and generation devices. This special issue would leads to a roadmap for young researchers in this field. Even though this special issue is open to all contributions related to energy generation and energy storage applications, but are not limited to the following applications such as electric vehicles, hybrid electric vehicles, renewable energies for smart micro grids, energy for cities, urban areas etc.
