The cycling performance of Li4Ti5O12 and LiMn2O4 electrode materials has been studied in half and complete Li-ion cells with two new polyfluorinated boron cluster lithium salts (Li2B12F x H12−x ) as the electrolytes. The results were compared with those obtained for the standard electrolyte, 1M LiPF6 dissolved in ethylene carbonate and dimethyl carbonate (EC:DMC; 1:1, v/v). Three different technologies were employed for electrode fabrication: powder mixture, self-standing films and films deposited on the current collector. The latter exhibit the most interesting behavior and best performance. Cells assembled using the new electrolyte salts show excellent reversibility, coulombic efficiency, rate capability and cyclability comparable with the standard electrolyte. These features confirm the feasibility of using these polyfluorinated boron cluster-based salts as new stable Li-ion battery electrolytes.
