阳极和阴极的替代配置，即纳米结构的 Sn-C 和空心碳球-硫复合电极，其特征在于用于钠离子硫电池的醚基电解质。电极的增强形态、高电导率和钠迁移数以及电解质的良好稳定性都是独特的特性，预计将有助于开发新型钠离子电池。事实上，这项工作报告的结果表明，该电池可以提供 550 mA h g(-1) 的卓越容量和 550 W h kg(-1) 的预期理论能量密度。
An alternative configuration of anode and cathode, i.e. nanostructured Sn-C and hollow carbon spheres-sulphur composite electrodes, are characterized here in an ether-based electrolyte for application in sodium ion-sulphur batteries. The enhanced morphology of the electrodes, the high values of conductivity and of sodium transference number, as well as the good stability of the electrolyte are unique properties that are expected to allow the development of a new sodium ion cell. Indeed, the results reported in this work show that this cell can provide a remarkable capacity of 550 mA h g(-1) and an expected theoretical energy density of 550 W h kg(-1).
