Compatibility of LixTiyMn1-yO2 (y = 0,0.11) Electrode Materialswith Pyrrolidinium-Based Ionic Liquid Electrolyte Systems
The possibility of using electrolyte systems based on roomtemperature ionic liquids (RTILs) in lithium battery configurations isdiscussed. The nonflammability and wide voltage windows of RTIL-basedsystems are attractive potential advantages, which may ultimately lead tothe development of safer, higher energy density devices than arecurrently available. An evaluation of the compatibility of theseelectrolyte systems with candidate electrodes is critical for furtherprogress. A comparison of the electrochemical behavior of Li/RTIL/LixMnO2and LixTi0.11Mn0.89O2 cells with those containing conventional carbonatesolutions is presented and discussed in terms of the physical propertiesof two RTIL systems and their interactions with the cathodes. Strategiesto improve performance and minimize cathode dissolution arepresented.
