%T Compatibility of Lix TiyMn1-y02 (y=0,0.11) electrode materials with pyrrolidinium-based ionic liquid electrolyte systems
%V 155
%X <p>The possibility of using electrolyte systems based on room-temperature ionic liquids (RTILs) in lithium-battery configurations is discussed. The nonflammability and wide potential windows of RTIL-based systems are attractive potential advantages, which may ultimately lead to the development of safer, higher energy density devices than those that are currently available. An evaluation of the compatibility of these electrolyte systems with candidate electrodes is critical for further progress. A comparison of the electrochemical behavior of Li/RTIL/Li<sub>x</sub>MnO<sub>2</sub> and Li<sub>x</sub>Ti<sub>0.11</sub>Mn<sub>0.89</sub>O<sub>2</sub> cells with those containing conventional carbonate solutions is presented and discussed in terms of the physical properties of two RTIL systems and their interactions with the cathodes. Strategies to improve performance and minimize cathode dissolution are presented.</p>
