Electrode Materials for High-Performance Sodium-Ion Batteries

Abstract

Sodium ion batteries (SIBs) are being billed as an economical and environmental alternative to lithium ion batteries (LIBs), especially for medium and large-scale stationery and grid storage. However, SIBs suffer from lower capacities, energy density and cycle life performance. Therefore, in order to be more efficient and feasible, novel high-performance electrodes for SIBs need to be developed and researched. This review aims to provide an exhaustive discussion about the state-of-the-art in novel high-performance anodes and cathodes being currently analyzed, and the variety of advantages they demonstrate in various critically important parameters, such as electronic conductivity, structural stability, cycle life, and reversibility.

FeTiO3 as Anode Material for Sodium‐Ion Batteries: from Morphology Control to Decomposition

“…At the same time, the technology of sodium‐ion batteries (SIBs) is still not mature, particularly the development of new electrode components represents a crucial issue. Many different materials have been investigated ranging from alloy, to carbon‐based systems, and transition metal oxides . Between them ilmenite (FeTiO 3 ), has been recently proposed as possible negative electrode material for lithium and sodium‐ion batteries and for sodium‐ion supercapacitor thanks to the high theoretical capacity, chemical stability and low cost.…”

Beyond Lithium-Based Batteries

“…Below we extract the main topics and points. Readers interested in more detail are referred to specific overviews on Na-ion batteries [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43].…”

Design, characterization, and application of elemental 2D materials for electrochemical energy storage, sensing, and catalysis

“…Whereas graphite cannot accommodate Na + ions, graphene can provide larger interlayer distances to store a larger number of Na + ions. 225,226 Wang et al reported rGO as an anode in SIBs for the first time in 2013. 225 The as synthesized rGO allowed significant Na + ion insertion because of its large interlayer distances (B0.371 nm) and disordered structures.…”
