Abstract:

With the advancement of the carbon neutrality and the rapid development of renewable energy, energy storage technology has become a crucial pillar for addressing energy transition and sustainable development. Redox flow battery (RFB) is an electrochemical device used for large-scale energy storage. It has the characteristics of flexible design, large storage capacity, long cycle life, and high safety. However, limited by the solubility of redox mediator molecules, its energy density is relatively low, and there are few practical systems. To meet this challenge, energy storage technologies based on solid-liquid redox-targeting reactions, i.e. redox-targeting flow batteries (RTFBs) have emerged to enhance energy density, maintain excellent flowability and elevate the constraint of traditional RFBs. This review provides a comprehensive perspective of recent research progress in materials, devices, and kinetics related to RTFBs including characteristics of various materials, the design and performance of devices, as well as the characterization and modeling of kinetic processes. The bottleneck of current research is summarized and the insights into future development trends are also provided.

摘要:

随着双碳政策的推进和可再生能源的快速发展,能源存储技术成为解决能源转型和可持续发展的关键支撑。氧化还原液流电池(RFB)是一种用于大规模储能的电化学器件,具有设计灵活、存储容量大、循环寿命长、安全性高等特点。然而受氧化还原介质分子溶解度的限制,其能量密度相对较低,同时可实用化的体系较少。为解决这一问题,基于固液氧化还原靶向反应的能量存储技术应运而生。氧化还原靶向液流电池(RTFB)在提高能量密度的同时保持良好流动性,克服了传统RFB的限制。综述了近年来该技术在材料、器件及动力学方面的研究进展,包括各种材料的特点、器件的设计及性能以及动力学过程的表征与建模。最后总结当前研究的不足之处并展望未来发展趋势。
