The purpose of this paper is to suggest frontier inter‐disciplinary research directions that can be considered as important horizons of modern electrochemistry in the field of energy storage and conversion. We selected several topics that call for advancements in solid‐state, interfacial, analytical and energy‐related electrochemical science. A dramatic improvement in the performance of energy storage and conversion devices is needed to meet the urgent demands of our society. Significantly more efficient devices are needed to meet two major challenges: electro‐mobility, namely electrochemical propulsion of electric vehicles, and the ability to store and convert large quantities of energy generated from sustainable sources such as sun and wind. We suggest promotion of breakthroughs in several important directions. The examples chosen include: Development of novel in‐situ methodologies for design and testing composite electrodes for advanced energy storage devices; Improving the electrochemical performance of high specific capacity, but hard to control, LiNiO2 cathodes for advanced lithium ion batteries designed for electric vehicles, with a quantitative goal of stable specific capacity >230 mAh/g with a charging potential lower than 4.3 V; Advancing aqueous electrochemical systems for large energy storage based on sodium electrochemistry; Promoting development of batteries based on multivalent active metals with magnesium as the most advanced example. There is a strong incentive to promote fundamental and practical progress in the field of rechargeable Mg batteries using new electrodes’ configurations and advanced electroanalytical methods. All these directions require deep efforts in basic, fundamental studies, in order to reach important practical goals.

与储能和转化相关的现代电化学技术的前景

本文的目的是提出前沿的跨学科研究方向,这些方向可被视为现代电化学在能量存储和转换领域的重要视野。我们选择了几个需要在固态,界面,分析和与能源有关的电化学科学方面取得进展的主题。为了满足社会的迫切需求,需要大幅改善储能和转换设备的性能。需要显着提高效率的设备来应对两个主要挑战:电动汽车,即电动汽车的电化学推进,以及存储和转换由可持续资源(例如太阳和风)产生的大量能量的能力。我们建议在几个重要方向上促进突破。选择的示例包括:设计和测试用于先进储能设备的复合电极的原位方法;改善高比容量但难以控制的LiNiO 2的电化学性能用于电动汽车的高级锂离子电池的阴极,其定量目标是稳定的比容量> 230 mAh / g,充电电势低于4.3 V;推进基于钠电化学的用于大型能量存储的水性电化学系统;以镁为最先进的例子,促进基于多价活性金属的电池的开发。在使用新的电极配置和先进的电分析方法的可再充电镁电池领域,有强烈的动机促进基本和实际的进步。所有这些方向都需要在基础,基础研究中进行深入的努力,以实现重要的实践目标。
