Abstract
Organic-inorganic hybrid solid electrolytes composed of Li+-conducting lithium aluminum germanium phosphate (LAGP), poly(ethylene oxide) (PEO), lithium perchlorate and succinonitrile (SN) were prepared in the form of flexible thin film, and their electrochemical properties were investigated. The hybrid solid electrolytes showed high ionic conductivities ranging from 3.0Â ÃÂ 10â5 to 1.1Â ÃÂ 10â4Â SÂ cmâ1 at room temperature and exhibited good electrochemical stability. A solid-state Li/LiFePO4 cell assembled with hybrid solid electrolyte composed of 70Â wt.% LAGP, 21Â wt.% PEO-LiClO4 and 9Â wt.% SN delivered a high discharge capacity and exhibited good capacity retention at ambient temperature. Good cycling performance of the cell resulted from the high ionic conductivity of the solid electrolyte and its good interfacial contacts with electrodes.
