摘要：

This manuscript reports on the development of a safe and green lithium-ion battery containing sodium salt of CarboxyMethylCellulose (CMC) as binder lithium tit mate (Li4Ti5O12) as anodic active material lithium iron phosphate (LiFePO4) as cathodic active material and an electrolytic solution based on the ionic liquid N-butyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide (PYR14FSI) The battery showed at room temperature a very stable specific capacity of 140 mAh g(-1) constant for more than 150 cycles This indicated that the introduction of low cost and environmentally benign binders like CMC and nonflammable electrolytes such as PYR14FSI represents a viable strategy for the development of new greener and safer lithium-ion batteries (C) 2010 Elsevier B V All rights reserved
