Overview
ABSTRACT
Sodium-ion battery technology appears to be complementary to Li-ion battery systems, and in line with sustainable policies. In this article, we first describe the working principle of such a sodium-ion battery. Then, the materials used or possibly used as anode and cathode are depicted. For the negative electrode, hard carbon remains the most used material, even if other insertion, alloy or conversion materials are promising. For positive electrode materials, the different species can be classified in three families: Prussian blue analogs, polyanionic materials and transition metal oxides.

INTRODUCTION
As part of sustainable development policies, many technologies are the subject of scientific research in laboratories. Among these technologies, electrochemical accumulators such as alkaline-ion batteries have taken pride of place in our daily lives. This is reflected in the democratization of the lithium-ion battery, widely deployed for mobile applications (cell phones and laptops, electric vehicles). However, other complementary technologies such as sodium-ion batteries need to be optimized in view of the inevitable development of an energy mix. These batteries are particularly interesting electrochemical accumulators for stationary applications, especially for intermittent energy storage (solar, wind). Na-ion batteries have the particular advantage of involving non-critical, eco-responsible elements in the development of electrode materials, which have yet to be optimized.
In this article, the operating principle of a Na-ion battery is explained, and its performance is compared with that of its larger Li-ion sibling. We then present the negative and positive electrode materials used in these batteries, and the solid-state chemistry involved, in the light of current knowledge. Anodes are presented according to the types of chemistry underlying them vis-à-vis sodium (intercalation, alloying, conversion reactions); for materials used as cathodes, a classification according to phase crystallochemistry is provided: Prussian blue analogues, polyanionic systems and transition metal oxides.
