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.

一种由稻壳多孔硬碳阳极和磷酸钒钠组成的li+/Na+混合可充电电池

随着对经济实惠且安全的能源存储选择的需求激增，对有效结合锂离子电池（lib）和钠离子电池（sib）优势的混合离子电池的追求正在获得动力。本研究介绍了一种创新的混合锂/钠离子全电池（HIB），其特点是多孔硬碳（PHC）阳极和高能钠基阴极Na3V2(PO4)3 （NVP）。组装后，这些hib显示出令人称道的工作电压约为3.5 V，放电特定容量为92.9 mAh/g。此外，它们在高速率性能、循环稳定性和可逆容量方面显示出令人印象深刻的能力。通过非原位XRD和非原位XPS分析，初步研究了该混合电池的反应动力学和锂/钠的插入和提取机理。本研究为混合离子电池技术的进一步发展开辟了新的途径和前景。
