Abstract

A series of novel nano-composite polymer electrolytes (NCPEs) are prepared with the ionic liquid of N-methyl-N-methoxyethylpiperidiniumbis(trifluoromethanesulfonyl)imide (PP_12O1TFSI) as plasticizer and nano-sized TiO₂ as additive. The effect of the ratio of TiO₂ to Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) on the properties of the NCPEs are studied, such as the crystallinity and ionic conductivity. The results indicate that the nano-composite polymer electrolyte NCPE-2, that the ratio of TiO₂ to PVDF-HFP is 10%, exhibits the highest ionic conductivity of 2 × 10^{- 3} S·cm^{- 1} with the lowest crystallinity. The LiFePO₄/NCPE-2/Li coin-typed cell cycled at 0.5 C shows the 1st discharge capacity of 127.9 mAh g^{- 1} and remains 97.6% of the initial discharge capacity on the 50th cycle.
