电池是未来柔性能源系统的关键技术之一。特别地，钒氧化还原液流电池（VRFB）由于诸如长循环寿命、容易放大和良好的可回收性的有利特性而非常适合于提供模块化和可扩展的能量存储。然而，有关其生产及营运的潜在环境影响，缺乏详细的原创性研究。本研究填补了这一空白，提供了一个全面的生命周期评估的代表性VRFB。公开透明和全面的清单数据，作为进一步环境研究的基础。VRFBs被认为是有前途的评估影响类别，特别是在高能源功率比（E/P）。另一方面，五氧化二钒生产会产生重大影响，这就是为什么含钒矿石的来源和加工是进一步减少与VRFB生产相关的环境影响的关键。虽然与例如锂离子电池（LIB）相比，VRFB的较低效率是一个缺点，但其可回收性明显更高。从这个意义上说，在比较非常不同的电池系统时，采取摇篮到摇篮的生命周期观点的重要性可以突出，以进一步研究这一主题。
Batteries are one of the key technologies for flexible energy systems in the future. In particular, vanadium redox flow batteries (VRFB) are well suited to provide modular and scalable energy storage due to favorable characteristics such as long cycle life, easy scale-up, and good recyclability. However, there is a lack of detailed original studies on the potential environmental impacts of their production and operation. The present study fills this gap by providing a comprehensive life cycle assessment of a representative VRFB. Transparent and comprehensive inventory data are disclosed as a basis for further environmental studies. VRFBs are found to be promising regarding the assessed impact categories, especially at high energy-to-power (E/P) ratios. On the other hand, significant impacts are associated with the vanadium pentoxide production, which is why the origin and processing of the vanadium bearing ores are a key for further reducing the environmental impacts associated with the VRFB manufacturing. While the lower efficiency of the VRFB is a disadvantage in comparison to e.g. lithium-ion batteries (LIB), its recyclability is significantly higher. In this sense, the importance of taking a cradle-to-cradle life cycle perspective when comparing very different battery systems can be highlighted for further research on this topic.
