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.

The influences of rapid quenching on the structures and electrochemical behaviors of La-Mg-Ni system (PuNi3-type) La0.7Mg0.3Co0.45Ni2.55-xFex (x = 0, 0.1, 0.2, 0.3, 0.4) electrode alloys were systemically investigated. The results show that the rapid quenching, instead of changing the phase structures of the alloys, leads to c axis enlarged and the a axis and cell volumes of the LaNi5 and (La, Mg)Ni3 major phases decreased slightly. The morphologies of the as-quenched alloys exhibit a massive structure, which differ from that of the as-quenched AB5-type alloy. The rapid quenching clearly impairs some electrochemical performances of the alloys, involving discharge capacity, high rate discharge ability (HRD) and discharge potential, but it significantly prolongs the cycle life of the alloy. With an increase in the quenching rate from 0 (As-cast was defined as quenching rate of 0 m/s) to 30 m/s, the discharge capacity of the alloy (x = 0.4) decreases from 351.06 to 313.36 mAh/s, the HRD from 69.36 to 50.54%, whereas its cycle life increases from 106 to 166 cycles at a charging discharging current density of 600 mA/g.

Sodium ion batteries (SIBs) have drawn interest as a lithium ion battery (LIB) alternative owing to their low price and low deposits. To commercialize SIBs similar to how LIBs already have been, it is necessary to develop improved anode materials that have high stability and capacity to operate over many and long cycles. This paper reports the development of homogeneous Sb2S3 nanorods (Sb2S3 NRs) on reduced graphene oxide (Sb2S3 NRs @rGO) as anode materials for SIBs. Based on this work, Sb2S3 NRs show a discharge capacity of 564.42 mAh/g at 100 mA/g current density after 100 cycles. In developing a composite with reduced graphene oxide, Sb2S3 NRs@rGO present better cycling performance with a discharge capacity of 769.05 mAh/g at the same condition. This achievement justifies the importance of developing Sb2S3 NRs and Sb2S3 NRs@rGO for SIBs.
