Abstract
Poly(ethylene oxide) (PEO)-coated separators were prepared by coating PEO o nto a microporous polyethylene (PE) separators. Highly conductive electroly tes were prepared by soaking them in an electrolyte solution. The uptake of the electrolyte solution and the ionic conductivity of the PEO-coated sepa rator (PCS) after soaking in LiBF4-ethylene carbonate (EC)/dimethyl carbona te (DMC) were measured to be 76% and 1.0 x 10(-3) S/cm. respectively. With these PCSs, lithium-ion cells composed of mesocarbon microbead (MCMB) anode and LiCoO2 cathode were assembled, and their electrochemical performances were evaluated.
