“…In the full cell assembly with hard carbon anode, it exhibits output voltage of 4.36 V with 95% capacity retention over 200 cycles at 1 C rate (X. Liu et al, 2019). Ramesh et al used sol–gel synthetic route to prepare Na 4 Co 3 (PO 4 ) 2 P 2 O 7 ‐MWCNTs in which the redox couple Co 3+/2+ appears at around 4.45 V versus Na + /Na during discharge (Kumar et al, 2020). In case of Na 4 Ni 3 (PO 4 ) 2 P 2 O 7 shows the redox Ni 3+ /Ni 2+ potential around 4.8 V versus Na with a theoretical capacity of 127 mAh/g (Kumar et al, 2019).…”

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.

Carbon nanotubes (CNTs) are an extraordinary discovery in the area of science and technology. Engineering them properly holds the promise of opening new avenues for future development of many other materials for diverse applications. Carbon nanotubes have open structure and enriched chirality, which enable improvements the properties and performances of other materials when CNTs are incorporated in them. Energy storage systems have been using carbon nanotubes either as an additive to improve electronic conductivity of cathode materials or as an active anode component depending upon structural and morphological specifications. Furthermore, they have also been used directly as the electrode material in supercapacitors and fuel cells. Therefore, CNTs demand a huge importance due to their underlying properties and prospective applications in the energy storage research fields. There are different kinds of carbon nanotubes which have been successfully used in batteries, supercapacitors, fuel cells and other energy storage systems. This chapter focuses on the role of CNTs in the different energy storage and conversion systems and impact of their structure and morphology on the electrochemical performances and storage mechanisms.

“…In this context, the polyanionic compounds, owing to their 3D framework, structural and thermal stability are considered potential candidates [14]. For example, the mixed phosphates with general formula Na 4 M 3 (PO 4 ) 2 P 2 O 7 (M=Fe, Mn, Co, Ni) have attracted great attention as new class of electrode materials due to the low volume expansion arising from the strongly covalent bonded framework with the excellent cycling performance and longer lifetime of the battery system [20][21][22][23][24][25][26]. These mixed phosphate materials have three dimensional orthorhombic framework containing MO 6 octahedra and PO 4 tetrahedra sharing corners with pyrophosphate group via P-O-P interlayer linkage [27].…”

“…In comparison to the ion diffusivity in 1D ion channel, the 3D ion channels have greater advantage due to the availability of the alternative diffusion pathways, which exist even if defects in the bulk hinders the ion mobility in one particular direction of 3D ion channel [22][23][24][25][26][27][28][29]. More importantly, due to the availability of large 3D channels in the Na 4 Co 3 (PO 4 ) 2 P 2 O 7 (NCPP), it can be considered as a good 3D ionic conductor [22][23][24][25][26][27][28][29]. It also shows low-volume expansion during the cycling and has the high theoretical capacity (170 mAhg −1 ).…”

“…As discussed above, recently the NCPP materials have been investigated in the high potential range as cathode [22][23][24][25][26][27][28][29]; however, to the best of our knowledge, its electrochemical investigation has not been explored so far in the lower working potential as anode in sodium-ion batteries. Therefore, in this paper we report the synthesis of a composite of N-doped carbon and NCPP via a facile solgel route and examine its electrochemical performance as a negative electrode (anode) for SIBs and compared with the pristine NCPP material.…”

In recent years, the mixed phosphates based polyanionic electrode materials have attracted great attention in sodium-ion batteries due to their structural stability during cycling and open framework for ion diffusion. Here, we report the electrochemical performance of Na4Co3(PO4)2P2O7/nitrogen doped carbon (NCPP/NC) composite as a negative electrode (anode) for sodium ion batteries in the working potential range of 0.01-3.0 V. It delivers a reversible discharge capacity of 250 mAhg −1 at 0.5 C current rate, which corresponds to the insertion/extraction of four sodium ions. The rate capability study indicates the reversible mechanism and highly stable capacity (61 mAhg −1 ) even at high rate up to 5 C as compared to pristine NCPP. The incorporation of the N doped carbon spheres in the composite is expected to enhance the electronic/ionic conductivity, which plays an important role in improving the performance and stability up to 400 cycles at 1 C rate. Intriguingly, the analysis of cyclic voltammetry data measured at different scan rates confirm the capacitive/diffusive controlled mechanism and the extracted diffusion coefficient is found to be around 10 −10 cm 2 s −1 . Our results demonstrate that the NCPP/NC composite is also a potential candidate as anode in sodium-ion batteries due to its three dimensional framework, cost effectiveness, enhanced specific capacity as well as further possibility of improving the stability.
