Electrochemical energy storage is a rapidly advancing field building on a continuous stream of innovative ideas. As renewable energy sources become increasingly prevalent the need for high energy-density, high- power storage devices with long cycle lives are greater than ever. The development of suitable materials for these devices begins with a complete understanding of the complex processes that govern energy storage and conversion spanning many orders of magnitude in length and time scales. Furthermore, new battery technologies have to be not only commercially and technically viable, but they should also deliver a lower environmental impact than the current state of the art. Therefore, a major challenge of modern battery technologies is to ensure that newly developed batteries are safe, efficient and follow the highest environmental and social standards at the level of production, use and disposal in a frame of a circular economy. Several emerging battery technologies are currently on endeavour to take a share of the dominant position taken by Li-ion batteries in the field of energy storage. Among them, sodium-based batteries offer a combination of attractive properties i.e., low cost, sustainable precursors and secure raw material supplies. Na-based batteries include related battery concepts, such as Na-ion, all solid-state Na batteries, Na/O2 and Na/S, that differ in key components and in redox chemistry, and therefore result in separate challenges and metrics. This paper aims at highlighting the most promising materials in the field of Na-based batteries and challenges needed to be addressed to make this technology industrially appealing, by providing an in-depth analysis of performance metrics from recent literature. The aim of this work is to present the new materials that are used in Na-based energy storage device. In particular will be presented new material for the use like positive or negative electrode and also new electrolytes, in particular solid electrolytes.
