Electrochemical devices, especially energy storage, have been around for many decades. Liquid electrolytes (LEs), which are known for their volatility and flammability, are mostly used in the fabrication of the devices. Dye-sensitized solar cells (DSSCs) and quantum dot sensitized solar cells (QDSSCs) are also using electrochemical reaction to operate. Following the demand for green and safer energy sources to replace fossil energy, this has raised the research interest in solid-state electrochemical devices. Solid polymer electrolytes (SPEs) are among the candidates to replace the LEs. Hence, understanding the mechanism of ions' transport in SPEs is crucial to achieve similar, if not better, performance to that of LEs. In this paper, the development of SPE from basic construction to electrolyte optimization, which includes polymer blending and adding various types of additives, such as plasticizers and fillers, is discussed.
电化学装置,特别是储能装置,已经存在了几十年。液体电解质(LEs)由于其挥发性和可燃性而被广泛应用于这些装置的制造。染料敏化太阳能电池(DSSCs)和量子点敏化太阳能电池(QDSSCs)也利用电化学反应来运行。为了寻找绿色、更安全的能源来替代化石能源,人们对固态电化学装置的研究兴趣日益浓厚。固态聚合物电解质(SPEs)是替代 LEs 的候选材料之一。因此,了解 SPE 中离子传输的机制对于实现与 LEs 相似(如果不是更好的话)的性能至关重要。本文讨论了从基本结构到电解质优化的 SPE 发展,包括聚合物共混和添加各种类型的添加剂,如增塑剂和填充剂。
