Abstract: A novel, simple and universal technique to fabricate flexible and freestanding electrode films was introduced. Three types of lithium ion batteries LiMn2O4/Li4Ti5O12, LiNi0.5Mn1.5O4/Li4Ti5O12 and LiNi0.5Mn1.5O4/graphite were assembled and tested. Lithium ion batteries fabricated using this method have high energy density and potential applications in some special areas. In addition, this technique may also be applied to in-situ spectroscopic research of lithium ion batteries.

Key words: lithium ion batteries, flexible, LiMn2O4, Li4Ti5O12, LiNi0.5Mn1.5O4
