应用于全固态电池的复合固态电解质的制备实验设计——综合化学实验教学探究

doi:10.3866/PKU.DXHX202308057

Abstract

Abstract:

A comprehensive chemistry experiment on Organic-Inorganic Composite Solid Electrolytes (SPE) is introduced, aiming to familiarize students with the modification strategies of Polyethylene Oxide (PEO) and the application of SPE in all-solid-state batteries. The experiment involves X-ray diffraction (XRD) characterization of crystal structure, as well as tests such as AC impedance, linear sweep voltammetry, and constant current charge-discharge to enhance students' understanding of concepts such as polarization and ion migration number. This experiment helps students extend theoretical knowledge to practical applications, improves their theoretical level, and enhances their practical skills.

Key words: Composite solid polymer electrolyte, Comprehensive chemical experiment design, Crystal structure characterization, Electrochemical characterization
