Organic batteries using redox-active polymers and small organic compounds have become promising candidates for next-generation energy storage devices due to the abundance, environmental benignity, and diverse nature of organic resources. To date, tremendous research efforts have been devoted to developing advanced organic electrode materials and understanding the material structure–performance correlation in organic batteries. In contrast, less attention was paid to the correlation between electrolyte structure and battery performance, despite the critical roles of electrolytes for the dissolution of organic electrode materials, the formation of the electrode–electrolyte interphase, and the solvation/desolvation of charge carriers. In this review, we discuss the prospects and challenges of organic batteries with an emphasis on electrolytes. The differences between organic and inorganic batteries in terms of electrolyte property requirements and charge storage mechanisms are elucidated. To provide a comprehensive and thorough overview of the electrolyte development in organic batteries, the electrolytes are divided into four categories including organic liquid electrolytes, aqueous electrolytes, inorganic solid electrolytes, and polymer-based electrolytes, to introduce different components, concentrations, additives, and applications in various organic batteries with different charge carriers, interphases, and separators. The perspectives and outlook for the future development of advanced electrolytes are also discussed to provide a guidance for the electrolyte design and optimization in organic batteries. We believe that this review will stimulate an in-depth study of electrolytes and accelerate the commercialization of organic batteries.

有机电池中的电解质
由于有机资源的丰富性、环境友好性和多样性，使用氧化还原活性聚合物和小有机化合物的有机电池已成为下一代储能设备的有希望的候选者。迄今为止，人们已经投入了大量的研究工作来开发先进的有机电极材料并了解有机电池中材料结构与性能的相关性。相比之下，尽管电解质对于有机电极材料的溶解、电极-电解质界面的形成以及载流子的溶剂化/去溶剂化发挥着关键作用，但人们对电解质结构和电池性能之间的相关性的关注较少。在这篇综述中，我们讨论了有机电池的前景和挑战，重点是电解质。阐明了有机电池和无机电池在电解质性能要求和电荷存储机制方面的差异。为了全面、透彻地概述有机电池电解质的发展，电解质分为有机液体电解质、水性电解质、无机固体电解质和聚合物电解质四类，介绍不同的成分、浓度、添加剂和在具有不同电荷载体、界面和隔膜的各种有机电池中的应用。还讨论了先进电解质未来发展的观点和展望，为有机电池电解质设计和优化提供指导。我们相信这次审查将刺激电解质的深入研究并加速有机电池的商业化。
