摘要

The efficient and high energy storage in rechargeable lithium batteries has enabled portable electronic equipment, the demands on which are ever increasing as it also appears to be the technology of choice for electrical vehicles. Additionally, rechargeable lithium batteries appear to be suitable technology to stabilize the electrical grid and to lift the intermittency of renewable energy on a daily basis. Although lithium is relatively abundant in the Earth's crust, it is unevenly distributed and it is questionable if it can meet the vastly increasing demands [1]. The chemical similarity of sodium and lithium, and the fact that sodium is one of the most abundant and easy to harvest elements in the Earth's crust have motivated the rapidly developing Na-ion battery research field [1-4]. Guo et al. [5] introduced a new material design strategy that opened novel perspectives for the development of cheap high performance Na-ion batteries.
