Optimizing the Electrolyte Systems for Na 3 (VO 1-x PO 4 ) 2 F 1+2x (0≤x≤1) Cathode and Understanding their Interfacial Chemistries Towards High-Rate Sodium-Ion Batteries.

Invited for this month's cover is the group of Prof. Dr. Zhipeng Sun at the Guangdong University of Technology. The image shows how electrolyte composition and their interfacial chemistries play a crucial role in manipulating the cathode/electrolyte interphases (CEI) and their corresponding high-rate electrochemical performance for sodium-ion batteries.
