摘要
热电材料是一种能实现热能和电能之间相互转化的功能材料,可以对化石燃料燃烧、工业生产等过程产生的废热进行回收再利用,在小型热电发电机、太阳能电池、智能传感器等方面具有良好的应用前景。随着现代科技的发展,热电功能材料逐渐应用于小型可穿戴设备,这对热电材料的安全无毒、稳定高转换效率和柔性等提出新的要求。相较于电子型热电材料,离子型热电材料具有高Seebeck系数、柔性可拉伸性和低毒低污染等优点,因此不论在热电发电装置还是小型可穿戴设备上均具有很好的应用潜力。本文详细阐述了在热原电池、离子热电电容器等能量收集装置中的离子型热电材料的研究进展,并分析了离子热电材料在可穿戴能量转换装置应用中所面临的问题和挑战,以期为制备安全无污染、稳定高效的新型柔性可穿戴设备提供新的方向。
Thermoelectric material is a kind of functional material,which realizes the mutual conversion between thermal energy and electrical energy.It can recycle waste heat generated in the process of fossil fuel combustion and industrial production,and shows good application prospects in small thermoelectric generators,solar cells,and smart sensors,etc.Thermoelectric materials are gradually applied to small wearable devices with the development of modern technology,which puts forward new requirements for safety,non-toxicity,stable high conversion efficiency and flexibility of thermoelectric materials.Compared with electronic thermoelectric materials,ionic thermoelectric materials have the advantages of high Seebeck coefficient,flexible stretchability,low toxicity and low pollution,and have good application potential in both thermoelectric power generation devices and small wearable devices.In this paper,the research progress of ion gel-based thermoelectric materials in energy harvesting devices such as thermogenic batteries and ionic thermoelectric capacitors are discussed.The problems and challenges faced by ionic thermoelectric materials in the application of wearable energy conversion devices are analyzed,in order to provide new directions for the preparation of safe,pollution-free,stable and efficient new flexible wearable devices.
