Progress in lithium polymer battery R&D

In this paper the characteristics and performance of composite polymer elec trolytes formed by dispersing selected ceramic (e.g. gamma -LiAlO2, Al2O3, SiO2) powders in poly(ethylene oxide)-lithium salt (e.g. PEO-LiCF3SO3) matr ices, are reported and discussed. Particular emphasis is devoted to the rol e of these composite electrolytes in providing the conditions for stabilizi ng the interface with the lithium metal electrode, as well as for enhancing the electrolyte's overall transport properties. Finally, results based on tests of practical prototypes demonstrate that these unique properties allo w the development of new types of high performance, rechargeable lithium po lymer batteries.
