摘要
A series of comb-like thermoplastic polyurethane (TPU) with trimethylolpropane polyethylene glycol monomethyl ether(Ymer-N120), poly-terephthalic acid-3- methyl-1,5-amyl glycol ester diol(TPA-1000), isophorone diisocyanate and 1,4-butanediol were synthesized. Solid polymer electrolytes (SPEs) were fabricated by adding LiTFSI to TPU with the content of 20%. The influence of the amount of TPA-1000 and Ymer-N120 on properties of the SPEs was discussed. The results show that the relationship between the ionic conductivity of the SPEs and temperature is consistent with the Arrhenius equation. The glass transition temperature and tensile strength decrease with the increase of Ymer-N120 content. The comprehensive properties of electrolyte are obtained when the mass ratio of Ymer-120 and TPA-1000 is 1:2 (SPE4). The tensile strength of SPE4 is 0.88 MPa with the ionic conductivity of 1.07×10-4 S/cm at 80℃. The discharge capacity of the solid-state lithium battery assembled by SPE4 reaches 138 mA•h/g at 0.2 C under 80℃. © 2019, Editorial Board of Polymer Materials Science & Engineering.
