摘要：

We describe the synthesis of new lithium salts, based on bulky carbanions, substituted by strong electron withdrawing groups together with their electrochemical studies using high molecular weight host polymer poly(oxyethylene) POE. The ionic conductivities of lithium salts-POE complexes have been measured as a function of temperature by impedance spectroscopy. The new lithium salts exhibit a wide electrochemical window stability. Their dissolution in POE (M(W) = 5 x 10(6)) provides amorphous polymer electrolytes with high ionic conductivity.
