将光伏和风能储存在电池中可以解决这些可再生资源的间歇性供应与可变需求之间的不匹配问题。通过使用储存在电池外部的液体电解质，液流电池允许比固体电极电池更经济的长时间放电。我们报告了一种基于氧化还原活性有机分子的碱性液流电池，该分子完全由地球上丰富的元素组成，无毒，不易燃，可安全用于住宅和商业环境。该电池在室温附近以高功率密度有效地工作。这些结果证明了碱性液流电池中氧化还原活性有机分子的稳定性和性能，可能实现可再生能源的成本效益固定存储。
Storage of photovoltaic and wind electricity in batteries could solve the mismatch problem between the intermittent supply of these renewable resources and variable demand. Flow batteries permit more economical long-duration discharge than solid-electrode batteries by using liquid electrolytes stored outside of the battery. We report an alkaline flow battery based on redox-active organic molecules that are composed entirely of Earth-abundant elements and are nontoxic, nonflammable, and safe for use in residential and commercial environments. The battery operates efficiently with high power density near room temperature. These results demonstrate the stability and performance of redox-active organic molecules in alkaline flow batteries, potentially enabling cost-effective stationary storage of renewable energy.
