A Flexible Solid Polymer Electrolyte based Polymerized Ionic Liquid for High Performance Solid‐State Batteries

Von Wiley-VCH zur Verfügung gestellt

A solid polymer electrolytes (SPEs) with polymerized ionic liquid and LLZTO was prepared by common solution casting method. Solid-state batteries assembled with it displayed excellent charge-discharge performance and cycling stability.


Solid polymer electrolytes (SPEs) combine the benefits of ceramic electrolyte and polymer electrolyte, and have broad application prospects in high-energy lithium metal batteries. However, low Li+ conductivity and tensile strength are crucial elements that hinder the application of solid polymer electrolytes. In this paper, an effective solid polymer electrolyte was proposed to solve these problems. A polymerized ionic liquid (PIL) was chosen as the ionic transport material to synthesize three-dimensional cross-linked ion channels through thermal polymerization, which can effectively improve the ionic conductivity. This work is different from some other reports that add ionic liquid without C=C double bond. We used the vinyl ionic liquid (IL) as matrix via polymerization with azobis initiator (AIBN) and the obtained co-polymer has excellent flexibility and non-flowing character. Li6.4La3Zr1.4Ta0.6O12 (LLZTO) ceramic filler was added to enhance the thermal stability and tensile strength of the electrolyte. Meanwhile, solid-state batteries (SSBs) assembled with LiFePO4 cathode and high-voltage LiNi0.8Co0.1Mn0.1O2 cathode can deliver remarkable cell performance. This work presents an appropriate device for the structure of modern polymerized ionic liquid solid polymer electrolytes, and shows significant implication for the progress of high-property polymer electrolytes.
