Abstract

As the demand for affordable and safe energy storage options surges, the quest for hybrid ion batteries that effectively combine the strengths of Lithium-Ion Batteries (LIBs) and Sodium-Ion Batteries (SIBs) is gaining momentum. This study introduces an innovative hybrid lithium/sodium ion full battery (HIB), which features a porous hard carbon (PHC) anode and a high-energy sodium-based cathode, Na₃V₂(PO₄)₃ (NVP). Upon assembly, these HIBs demonstrate a commendable operating voltage of approximately 3.5 V, alongside a discharge-specific capacity of 92.9 mAh/g. Furthermore, they reveal impressive capabilities in terms of high-rate performance, cycling stability, and reversible capacity. The investigation into the reaction kinetics and the mechanisms behind lithium/sodium insertion and extraction in this hybrid battery was initially conducted through ex-situ XRD and ex-situ XPS analyses. This research opens up new avenues and perspectives for further advancements in hybrid ion battery technology.

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
