Because of the intermittent nature of renewable energy sources, energy storage facilities are attracting increasing attentions in the application of power grid. The market of energy storage facilities is expected to expand over twenty folds in the coming ten years and it can lead to the next billion-dollar industry. Electrochemical energy storage (EES) is favorable over other technologies in grid applications because of its flexibility in various power ratings and discharge time. Among available EES technologies, the redox flow battery is promising for stationary applications because its energy capacity and power ratings can be designed independently to meet various demands. In particular, the soluble lead-acid redox flow battery contains no expensive components and chemical, and has great potential to prevail in the energy storage market. However, it suffers from limited cyclability and its current technology cannot meet the durability requirement of grid applications. In this research, we aim to develop a soluble lead-acid redox flow battery as an energy storage device for the power grid in Taiwan. There are three main research directions to improve the efficiency and cyclability of lead-acid redox flow batteries based on our previous investigation: (1) design and development of three-dimensional architectural electrodes; (2) search of the optimal operation conditions and develop an electrochemical model for the analysis; (3) improve the battery performance by cell architecture redesign and develop battery stack technology. Ultimately, through the effort of this research we hope to facilitate the commercialization of soluble lead-acid redox flow batteries and the development of energy storage in grid applications.電網氧化還原液流電池鉛酸power gridlead acidredox flow battery
