Sodium-ion batteries: research of carbon-based negative electrode materials

Abstract

This paper is mainly focused on research of hard carbon as promising negative electrode material for sodium-ion batteries. The first part deals with batteries and their usage in general. The next section deals with sodium-ion batteries, their development and differences compared to lithium-ion, as they seem to be one of the promising post-lithium technologies with the potential of quick commercialization. The emphasis in this work is put on the negative electrode materials for sodium-ion batteries based on hard carbon as an active electrode material.
