项目摘要

With a number of advantages over other existing energy storage system (ESS) including flexibility, mobility, depth of discharge, rapid response, and safety, redox flow batteries (RFB) are one of the most promising and versatile options for grid scale energy storage, potentially enabling the integration of intermittent but growing fast renewable energy sources into power grids. RFB represent one class of electrochemical ESS and have been attracting attention over last two decades. Several chemistries of RFBs have been studied. However none of them fully meet the cost and performance requirements. Significant developments are required at all levels: investigation of new chemistries, materials engineering, cell design and long-term performance characterization in realistic environments.This project will investigate an innovative RFB system based on nickel and zinc redox couples. The zinc-nickel system is promising due to the low cost and material abundance of its redox couples, their environmentally acceptable chemistry, high standard electrode potential and high power and energy densities. The scope of this project is on the improvement of materials and engineering design, combined with advanced characterisation techniques and computational modelling to gain fundamental insights and accelerate progress towards a high-performance, durable cell design. The programme will be focused on ways to improve the morphology of thick zinc electrodeposits when subjected to multiple deposition/dissolution cycles, and methods to increase the charge capacity of the positive electrode in flowing electrolyte conditions.In addition, the system is a membrane-free flow battery, which differs from conventional flow battery technologies since it employs only a single electrolyte and therefore operates without a need in membrane separator; this reduces the cost and design complexity of the batteries significantly. Overall, the performance of the Zn-Ni battery should compare well with existing redox flow batteries.The project will be a collaborative research endeavour between highly experienced researchers with internationally recognised expertise in flow batteries from the University of Exeter, Imperial College London and the University of Warwick.

与其他现有的能量存储系统（ESS）相比，氧化还原液流电池（RFB）具有许多优点，包括灵活性、移动性、放电深度、快速响应和安全性，是电网规模能量存储的最有前途和通用的选择之一，有可能将间歇性但快速增长的可再生能源整合到电网中。RFB代表了一类电化学ESS，在过去的二十年中一直受到关注。已经研究了RFB的几种化学性质。然而，它们都不能完全满足成本和性能要求。在各个层面上都需要有重大的发展：新化学研究、材料工程、电池设计和现实环境中的长期性能表征。该项目将研究基于镍和锌氧化还原电对的创新RFB系统。锌-镍体系由于其氧化还原对的低成本和材料丰富、其环境可接受的化学性质、高标准电极电位以及高功率和能量密度而有希望。该项目的范围是改进材料和工程设计，结合先进的表征技术和计算建模，以获得基本的见解，并加速实现高性能，耐用的电池设计。该计划将侧重于如何改善厚锌电沉积物的形态时，受到多个沉积/溶解周期，和方法，以增加在流动的电解质条件下的正极充电容量。此外，该系统是一个无膜液流电池，其不同于常规液流电池技术，因为其仅使用单一电解质分离器;这显著降低了电池的成本和设计复杂性。总的来说，锌镍电池的性能应与现有的氧化还原液流电池相媲美。该项目将是一项合作研究，由埃克塞特大学、帝国理工学院伦敦和沃里克大学的经验丰富的研究人员共同努力，他们在液流电池方面具有国际公认的专业知识。
