Lower Cost and Longer Life Flow Batteries for Grid Scale Energy Storage

液流电池是一种电化学能量存储形式，其中电能通过产生物理上分离的还原剂和氧化剂来存储，当需要时通过氧化还原对的重新组合产生电能。与其他形式的电化学存储不同，液流电池的特点是能够分离功率和能量，在能源需求增加时大幅节省成本，并提供兆瓦/兆瓦级规模存储的潜力。近年来，这项技术已经取得了长足的进步，特别是在中国和英国，但仍然存在挑战，以了解和改善目前使用的全钒方法的寿命和性能，并探索显著降低成本的新方法。这项建议解决了液流电池的成本、性能和寿命问题，开发了显著改进的所有钒系统，并探索了新的方法。

Flow batteries are a form of electrochemical energy storage in which electrical energy is stored via the generation of a physically separated reductant and oxidant, and electrical energy generated when required by the re-combination of this redox couple. Unlike other forms of electrochemical storage, flow batteries are characterised by the ability to de-couple power and energy, allowing significant cost savings as energy requirements increase, and offering the potential for MW/MWhr scale storage. Considerable progress has been made on this technology recent years, especially within China and the UK, but challenges remain to understand and improve lifetime and performance in the currently used all vanadium approach, and to explore novel approaches which offer significantly reduced cost. This proposal addresses the issue of both cost, performance and lifetime within flow batteries, to develop significantly improved all vanadium systems, and to explore novel approaches.
