Rechargeable sodium-air batteries have been the focus in the fields of batteries and energy storage recently, owing to their high specific energy density (1600 Wh?kg-1), an equilibrium discharge potential of 2.3 V and earth-abundant sodium element. However, research on sodium-air cells is still in an infant age and presents many scientific issues. Based on recently reported work and our own experience on sodium-based batteries, this review summarizes the research progress related to the critical scientific issues of secondary sodium-air batteries and the application prospect of sodium-air battery.

In order to improve the reaction activity of VO2+/VO2+ and the battery performance of Vanadium redox flow battery,different concentration of potassium sulfocyanates KSCN were added into 0.1mol/L VOSO4/ H2SO4 solution,and the kinetic characters of electrochemical reaction of VO2+/VO2+ was studied by CV and EIS.The results showed that the addition of KSCN could improve the oxidative peak current value of positive couple VO2+/VO2+ reaction,but had little influence in the reductive peak.The addition of KSCN decreased the impedance at 1.0 V.And the value of standard rate constant k0 was also improved with the concentration of KSCN increased.The total coulomb during the charge …

Effect Of Heat Laminating Aggregation Status Of Polymer Lithium-Ion Battery Cathode On Battery Performance, Ming-Gang Jin, Quan-Feng Dong, Ming-Sen Zheng, Li Huang, Hui-Qun Cai, Jin-Qua You, Zu-Geng Lin
Journal of Electrochemistry
Multi_layer heat laminated polymer lithium ion battery was made, the effect of temperature of cathode laminating on battry performance was also investigated. It was discovered that suitable temperature of cathode laminating is critical to battery performance and is a key parameter to manufacture process control of polymer lithium ion battery.
