This review describes the use of Ionic Liquids (ILs) as solvents and supporting electrolytes for thermoelectrochemical cells. These generators are based on the Seebeck effect and are potential technologies to convert low-grade heat into electricity. The use of ILs as solvents in these devices is promising, as it expands the temperature range and temperature differences among electrodes that these thermocells can operate. Factors that influence the thermodynamics and efficiencies of IL thermocells are relatively well understood and will be summarized in this review. The manuscript is divided in two sections: pure ILs and IL solutions. Each section discusses the properties of thermocells with metallic and non-metallic redox couples. Perspectives on how to overcome efficiency limitations of these devices and perspectives for future research are given.

这篇评论描述了离子液体（ILs）作为热电化学电池的溶剂和支持电解质的用途。这些发电机基于塞贝克效应，是将低等级热量转化为电能的潜在技术。在这些设备中将IL用作溶剂是有前途的，因为它扩大了这些热电池可操作的电极的温度范围和温差。影响IL热电池热力学和效率的因素已得到相对较好的理解，并将在本综述中进行总结。手稿分为两部分：纯净IL和IL溶液。每个部分都讨论了具有金属和非金属氧化还原对的热电池的性能。给出了有关如何克服这些设备的效率限制的观点，并提出了未来研究的观点。
