摘要

这篇前瞻性文章总结了双离子电池的工作原理,并强调了解释和报告其电化学性能的主要问题。二次双离子电池(DIBs)是一种新兴的固定式储能系统,由于其低成本、高能效、功率密度和长循环寿命,已被积极探索。然而,对该领域文献的批判性评估指出,报告的性能存在许多不准确和不一致之处,主要是由于排除了使用过的电解质的容量和使用非电荷平衡电池造成的。最终,这些遗漏会对DIB的能量和功率密度的评估产生直接影响。为了确保DIB的进一步发展,在这项工作中,我们批判性地回顾了当前的研究成果,并总结了这种电池的运行机制。这一观点的重点是强调DIB电化学性能的解释和报告中的主要问题。为此,我们调查了这些固定存储系统的前景,强调了仍有待解决的实际障碍。

Building better dual-ion batteries
This perspective article summarizes the operational principles of dual-ion batteries and highlights the main issues in the interpretation and reporting of their electrochemical performance. Secondary dual-ion batteries (DIBs) are emerging stationary energy storage systems that have been actively explored in view of their low cost, high energy efficiency, power density, and long cycling life. Nevertheless, a critical assessment of the literature in this field points to numerous inaccuracies and inconsistencies in reported performance, primarily caused by the exclusion of the capacity of used electrolytes and the use of non-charge-balanced batteries. Ultimately, these omissions have a direct impact on the assessment of the energy and power density of DIBs. Aiming to secure further advancement of DIBs, in this work, we critically review current research pursuits and summarize the operational mechanisms of such batteries. The particular focus of this perspective is put on highlighting the main issues in the interpretation and reporting of the electrochemical performance of DIBs. To this end, we survey the prospects of these stationary storage systems, emphasizing the practical hurdles that remain to be addressed.
