Abstract

Sustainable and efficient energy storage devices are crucial to meet the soaring global energy demand. In this context, Na-ion batteries (NIBs) have emerged as one of the excellent alternatives to the Li-ion batteries, due to the uniform geographical distribution, abundance, cost-effectiveness, comparable operating voltage as well as similar intercalation chemistry. However, due to larger size of Na and other related issues, a subtle strategy of research is required for the development of electrode materials for NIBs to enhance overall electrochemical performance. Here, we provide a comprehensive review on recent advances of polyanionic cathode materials for NIBs for cost effective and large scale energy storage applications. Owing to their great thermal and chemical stability, high redox potential (inductive effect), and rich structural diversity, polyanionic cathodes have been considered potential candidates in recent years. We cover a large number of polyanionic materials and conclude with the strategies to improve the energy and power density of NIB. This article is categorized under: Energy Research & Innovation > Science and Materials Energy and Development > Science and Materials Energy and Transport > Science and Materials.
