Nanoflake-constructed porous Na3V2(PO4)3/C hierarchical microspheres as a bicontinuous cathode for sodium-ion batteries applications

Na 3 V 2 (PO 4 ) 3 @NC composite derived from polyaniline as cathode material for high‐rate and ultralong‐life sodium‐ion batteries

“…However, the intrinsic properties of these materials, such as serious capacity decay and voltage platform receding because of structural variations during Na + ‐intercalation/removal process or occurring the side reaction, hinder their application in SIBs. Compared with them, Na 3 V 2 (PO 4 ) 3 (NVP) with NASICON structure and higher theoretical specific capacity is considered as an ideal cathode material for SIBs . In addition, its stable 3D host framework brings about thermal stability and ultralong cycle life, although the low electronic conductivity of NVP causes inferior rate character, which limits its utilization .…”

“…[27][28][29][30] In addition, its stable 3D host framework brings about thermal stability and ultralong cycle life, although the low electronic conductivity of NVP causes inferior rate character, which limits its utilization. 29,31,32 In order to resolve this problem, various ways have been used to enhance the electrochemical properties of NVP, such as surface modification with conducting materials, ion doping, and controlling particle size. For instance, Li et al 33 gained NVP/C through solid-state reaction method, and glucose was used as the carbon source, which displayed the first discharge capacity of 98 mAh g −1 at 0.1 C and 76 mAh g −1 at 30 C. Zhang et al 34 obtained NVP/C using oxalic acid as carbon source, which have superior rate capability.…”

Designing Advanced Vanadium‐Based Materials to Achieve Electrochemically Active Multielectron Reactions in Sodium/Potassium‐Ion Batteries

“…In the meantime, other similar work is still continuously being reported with various types of well‐decorated carbon network/matrix. [ 138–141 ] Future tasks should be focused on how to maintain the designed morphologies of the carbon network/matrix in industrial‐level fabrication, as well as doping carbon with non‐metallic elements (e.g., N, B, and S) during large‐scale manufacturing.…”

Exploration of Energy Storage Materials for Water Desalination via Next-Generation Capacitive Deionization

“…Recently, sodium superionic conductors (NASICONs), such as NaTi 2 (PO 4 ) 3 (NTP) (Huang et al, 2017(Huang et al, , 2019Guo et al, 2018;Wang et al, 2018;Zhang et al, 2020) and Na 3 V 2 (PO 4 ) 3 (NVP) (Cao J. L. et al, 2019;Cao X. X. et al, 2019), have been considered as promising cathode materials for sodium ion battery due to their high theoretical specific capacity and high Na + conductivity. Yang and co-workers fabricated a hybrid CDI cell with NaTi 2 (PO 4 ) 3 /rGO as positive electrode and activated carbon (AC) as negative electrode.…”
