从电化学性能和成本的角度来看，膜是钒氧化还原液流电池(VRFB)的关键部件。标准材料Nafion(R)是成本密集型材料，因此有几种替代材料是研究的重点。在这篇文章中，提出了一个实质性的分析方法，以量化不同类型的膜的最低价格限制。通过对材料和生产成本的深入分析，可以说明不同离子交换膜(IEM)和纳米滤膜(NFM)的成本潜力。最终结果显示，在高产量下，IEM和NFM的预期成本相差一个数量级。此外，对目前的市场形势进行了分析，为目前的经济考虑提供了一个框架。(C)2015爱思唯尔B.V.保留所有权利。
The membrane is a key component of the vanadium redox flow battery (VRFB) in terms of electrochemical performance as well as costs. The standard material Nafion (R) is cost intensive and therefore several alternative materials are in the focus of research. In this paper a substantial analytical approach is presented in order to quantify bottom price limits for different types of membranes. An in-depth analysis of material and production cost allows statements concerning cost potentials of different ion exchange membranes (IEM) and nano filtration membranes (NFM). The final result reveals that expected costs of IEM and NFM at high production volumes differ by one order of magnitude. Moreover, an analysis of the current market situation is made to provide a framework for economic considerations at present. (C) 2015 Elsevier B.V. All rights reserved.
