摘要：

A simple and rapid method for the determination of LiCF3SO3 and gamma -LiAlO2 in composite PEO (poly(ethylene)oxide)-based polymer electrolytes, both in mixtures and thin films, is described. The method is based on the dissolution of LiCF3SO3 in anhydrous ethanol at room temperature and subsequently dissolution of PEO in water for the separation of gamma -LiAlO2. Determination of the lithium content in LiCF3SO3 and gamma -LiAlO2 was performed by flame atomic absorption spectrometry (FAAS). A fast and total recovery of the components is achieved, being within 99-100%. The analysis of variance (ANOVA) is used to estimate the contribution of variance of chemical analysis and sampling procedure to the total variance. The results from ANOVA show a high level of homogeneity of the samples. (C) 2001 Elsevier Science B.V. All rights reserved.
