Abstract In the 21st century, the era of fossil fuels such as oil will wane due to both energy and environmental concerns and the arrival of a new era of green renewable energy is expected. Solar energy, wind power, tidal power, and nuclear power are mentioned as the next generation energy, but it is difficult to use these kinds of energy for transportation such as vehicles due to their uneven energy production. From this perspective, the interest in energy storage technology is on the rise as a means to solve this problem. It is believed that commercially available Li-ion batteries (LIBs) are the most feasible alternatives from the viewpoint of current technical maturity and economic consideration. Although LIBs were successfully commercialized, a noticeable improvement in energy density of Li-ion cells is required to satisfy needs for high power and/or capacities for applications such as power tools, electric vehicles or efficient use of renewable energies. Moreover, the need for inexpensive and safe Li rechargeable battery materials for large-scale environmentally benign cells has intensified in recent years. In this presentation, we will highlight recent advancements in the development of high-energy-density LIBs and functional organic electrolytes that is an immediate technological solution for high performance LIBs.
