Topic: 13Abstract:
The density, viscosity and electrical conductivity of ionic liquid 1,3-diethylimidazolium bis(trifluoromethylsulfonyl)imide, (C2C2imTFSI), and 0.5 M solution of LiTFSI in C2C2imTFSI were determined at different temperatures. The LiTFSI/C2C2imTFSI system was tested as a possible electrolyte for lithium-ion batteries by using anatase TiO2 nanotube arrays [1] electrode as anode material for a first time. The electrochemical testing has shown the improvement of lithium-ion insertion/deinsertion properties by increasing temperature. Also the existence of the decomposition of the electrolyte detects the change of colour. The decomposition of electrolyte leads to the formation of a film on the surface of the electrode [2,3] which improves coulombic efficiency during cycling.
