摘 要：The importance of enhancing up transference number of lithium ion to unit has been recognized by both numerical simulation and experiment,avoiding of concentration polarization and thus improve the battery *** single ion conductor requires the immobilization of super-weak coordinated anion in the polymer chain.4,4’-dicarboxyl bis(benzene sulfonyl)imide has been designed and synthesized as a building block to copolymerize with other small units to form a series of copolymers via *** the fact that the mobility of the main chain is restricted by the rigid amides,a bis sulfonyl imide included poly aryl ether polymeric single ion conductor has been *** ionic conductivity of the blend film is a high as 0.41 mS cm at room temperature with the lithium ion transference number of 0.93.A single ion conductive polymeric lithium ion full battery was assembled with the single ion conductor as the separator as well as the electrolyte,Li Fe PO4 mixed with ionomers as the positive electrode and LiTiO mixed with ionomers as the negative *** electrochemical performance for this full cell is shown in *** oxidation and reduction peaks of the full cell lies between that of LTO and LFP with the initial oxidation peak potential of 2.01 V and reduction peak potential of 1.68 *** full-cell delivers 125 mA h g at 0.05 C,112 mA h g at 0.1 C,108 mA h g at 0.2 C,103 mA h g at 0.4 C,95 mA h g at 0.6 C,83 mA h g at 0.8 C,68 mA h g at 1 C,and reverts to around 96 mA h g at 0.5 ***,the full cell keeps at 96 mA h g at 0.5 C for 100 cycles with 100 % of coulombic efficiency,indicating a well-connected ion transport network in the full cell as well as stable SEI films.
