“…In addition, P2‐type Na 2/3 (Fe 1/2 Mn 1/2 )O 2 hierarchical nanofibers was synthesized via electrospinning technique by Kalluri et al Such unique hierarchical nanofibers as the cathode for SIBs display an initial discharge capacity of ≈195 mA h g −1 and improved cycling performance with a capacity retention of 86.4% after 80 cycles. Among tunnel‐structure materials, Na 0.44 MnO 2 is particularly attractive on account of its wide tunnel structure which can greatly facilitate the insertion/extraction of Na + . Fu et al fabricated two types of Na 0.44 MnO 2 hierarchical structures (nanofibers and nanorods) by optimized electrospinning and controlled subsequent annealing procedure.…”

Sodium-ion batteries (SIBs) have received extensive attention as ideal candidates for large-scale energy storage systems (ESSs) owing to the rich resources and low cost of sodium (Na). However, the larger size of Na and the less negative redox potential of Na /Na result in low energy densities, short cycling life, and the sluggish kinetics of SIBs. Therefore, it is necessary to develop appropriate Na storage electrode materials with the capability to host larger Na and fast ion diffusion kinetics. 1D materials such as nanofibers, nanotubes, nanorods, and nanowires, are generally considered to be high-capacity and stable electrode materials, due to their uniform structure, orientated electronic and ionic transport, and strong tolerance to stress change. Here, the synthesis of 1D nanomaterials and their applications in SIBs are reviewed. In addition, the prospects of 1D nanomaterials on energy conversion and storage as well as the development and application orientation of SIBs are presented.

“…For x = 0 sample, there are six distinct peaks in the oxidation, which repeats in the reduction as well as upon cycling indicating reversibility of Na ion in extraction/insertion. The multi peaks in the CV indicate a complex phase evolution where each peak corresponds to the extraction of Na from different crystallographic sites in the structure [13]. The difference between oxidation and reduction peak values is a measure of the number of free electrons (or Na-ion) involved in the charging/discharging and is given by ∆E=59/n meV (at room temperature) [36], where, ∆E is the difference between the oxidation and corresponding reduction peaks and n is the number of electrons involved.…”

“…Such deficiency can be resolved by altering the morphology (surface to volume ratio) by optimizing the growth technique. There have been various modified techniques employed for the synthesis of Na 0.44 MnO 2 [15][16][17][18], such as reverse microemulsion method [6,19], polymer-pyrolysis method [11], modified pechini method [14,20] and optimized solid state reaction method [13]. Apart from the synthesis, introduction of some disorder in the electrode material, especially in the form of doping, has been found to be increasing the capacity and performance of the electrode material [1,4,8,21].…”

We report the synthesis, physical properties and electrochemical performance of Zn substituted Na0.44Mn1−xZnxO2 (x = 0 -0.02) nanostructures as cathode in Na-ion batteries for energy storage applications. These samples stabilize in the orthorhombic structure and the morphology is found to be slab like with 100 -200 nm width and few micrometer of length. The resistivity measurements show highly insulating nature for all the samples, where the activation energy decreases with increasing Zn concentration indicating more defect levels in the band gap. The cyclic voltammogram (CV) shows reversible oxidation and reduction peaks, which clearly shift towards higher/lower potentials with increasing Zn concentration up to 2%. We observed the specific capacity of about 100 mAh/g at current density of 4 mA/g and improved cycle life for Zn substituted x = 0.005 sample. However, with further increasing the Zn concentration (x = 0.02), the specific capacity decreases, which can be a manifestation of the decreased number of reduction peaks in the CV data.

Advanced Cathode Materials for Sodium‐Ion Batteries: What Determines Our Choices?

lithium with cheaper alternatives might make future batteries less susceptible to price fluctuations when the market expands. [5] This concern has in turn spawned a flurry of research activity to look beyond LIB technology. In view of the various rechargeable batteries, sodiumion batteries (SIBs) that consist of a main element of seawater made their presence felt in the battery industry due to their chemical similarity (e.g., only 0.3 V more positive than lithium) but higher abundance compared to lithium, [6] as illustrated in Table 1. SIBs work in the same way as LIBs in that they involve the reversible migration of cations/anions across a separator toward the electrodes to realize voltage-driven electrochemical reactions. [7] The upward trend for sodium-ion battery research is driven by the concern over the scarcity and price rise of lithium. Hence, these major merits, as well as the suitable redox potential (E = 0.3 V vs Li) make the SIB an appropriate choice as a rechargeable battery system.In fact, SIBs started almost in parallel with LIBs in the 1980s but the development of LIBs eventually eclipsed SIBs due to the electrochemical performances of SIBs. [8,9] A major obstacle is that it is difficult to get a sodium host material with comparable operating voltage and capacity as the LIB analogs. Firstly, the larger Na + radius (0.98 Å) than that of Li + (0.69 Å) leads to the kinetically sluggish Na + insertion/extraction and transport cross the host-material framework, which will always make the specific capacity and rate capacity largely degraded. [10] Secondly, the larger volume expansion caused by Na + insertion will also bring a change in the phase and lattice of the host materials, making it difficult to achieve a favorable electrochemical stability compared with the LIB counterparts. [11] In addition, they also suffer from a lower specific energy than LIBs, due to the lower potential and larger atomic weight of sodium. It is still a challenge to build an affordable Na-host materials endowed with a high specific energy (e.g., 500 W h kg −1 in LIBs). [12] Recently, the topic of SIBs was revisited in the hope of exploring possible ways to overcome the concerns about the low energy density and poor cycling life of SIBs.In spite of the above distinct drawbacks, SIBs can actually behave slightly differently in some chemical aspects. For instance, sodium does not react with aluminum, which is contrary to the alloying tendency of lithium. In the commercial market, manufacturers could appreciate this "inertness" to reduce the production cost of batteries by substituting the Among the various energy solutions, lithium-ion batteries (LIBs) play an important role in the process of the transition from fossil fuels to renewables. However, the necessity to replace lithium with cheaper alternatives due to its scarcity has recently attracted great interest to developing sodium-ion batteries (SIBs). Hence, the discovery and development of suitable cathode materials that exhibit high specific capacity, good cycling stabil...
