Inside Back Cover: A Multi-Ion Strategy towards Rechargeable Sodium-Ion Full Batteries with High Working Voltage and Rate Capability (Angew. Chem. Int. Ed. 50/2018)
Graphical Abstract
A multi-ion strategy can enhance the electrochemical performance of sodium-ion batteries. In their Communication on page 16370 ff., Y. B. Tang et al. report a multi-ion configuration (Na+/Li+/PF6−) for sodium-ion full batteries by combining anion (PF6−) intercalation with a hybrid-ion design (Na+/Li+) electrolyte. The optimized batteries exhibited a high working voltage (ca. 4.0 V), a significantly enhanced rate performance, and superior cycling stability.
