“…Na is the fourth abundant element on the earth's crust making it economically feasible for use in large‐scale applications 74,76,77 . A price comparison gives 0.08$/equivalent for Sodium whereas 0.50$/equivalent for Li, 78 and is easily recyclable too 10,79‐82 . While making use of the SIB technology, although it provides the same intercalation chemistry as Li + 82,83 and storage mechanism, 84 the major challenge incurred is the sluggish Na + diffusion caused by a higher ionic radius of Na + (0.98 Å) in contrast with Li + (0.69 Å) 10,72,85,86 leading to large volume changes, low rate capability, and capacity fading during cycling 75,83,85,87 .…”

“…In contrast, the insertion/deinsertion of a single ion is suggested for the electrochemical reaction at 1.7 V. Consequently, the theoretical reversible capacity is only 58.8 mA h/g in the potential region between 3 and 1 V versus Na/Na + . , Besides these reasonable capacity values, the material is also expected to exhibit good rate capability and high stability due to its NASICON-type structure. In the literature, most of these key properties have been experimentally confirmed; however, in many cases, the reported cycling stability was limited. , An extremely high cycling stability was recently reported for NVP–Na metal cells , and an NVP–NVP cell with an ether-based electrolyte . Furthermore, NVP–NVP cells have been investigated for all-solid-state SIB. , In this work, we aim to clarify the discrepancies in the reliability of NVP and investigate the origins of degradation by comparing the performance of NVP in various electrolytes and different configurations.…”
