dc.description.abstract | Organic/inorganic hybrid semi-interpenetrating network electrolytes (HIPE) based on poly(ethylene oxide-co-ethylene carbonate) (PEOEC) have been developed for all-solid-state lithium battery applications. In comparison to poly(ethylene oxide) (PEO)-based electrolytes, the salient features of the PEOEC electrolytes are the amorphous nature and high dielectric constant, which provide enhanced ionic conductivity. The organic/inorganic hybrid network matrix in HIPE is composed of different contents of photo-cross-linked octa-functional POSS acrylate (OA-POSS) and ethoxylated trimethylolpropane triacrylate (ETPTA). The effect of OA-POSS on solid-state electrolyte properties of the HIPE is investigated in terms of dimensional stability, thermal behavior, and ionic conductivity. Due to the presence of the rigid and bulky POSS moiety, the HIPE exhibits improvement in ionic conductivity, along with enhanced dimensional stability. The high capacity and good cycle performance of lithium battery with the HIPE demonstrates the feasibility of applying the HIPE to solid-state electrolytes for all-solid-state lithium batteries. | - |
