Abstract Scope |
Solid state composite polymer electrolytes (CPE) comprising active ceramic filler inside a polymer matrix show great potential to be used as solid-state electrolyte in lithium-ion batteries owing to high Li+ conductivity. Garnet type Li7La3Zr2O12 (LLZO) fillers provide high ionic conductivity, good interfacial stability with lithium metal anode. We investigated that, by integrating 3D interconnected chain structured LLZO prepared by facile and scalable cotton templated synthesis method, the room temperature ionic conductivity of PVDF-LiTFSI based CPE increased to 3.96 × 10-4 S cm-1, which is almost ~4 times higher than particle shaped LLZO prepared using conventional sol-gel method. The cotton templated LLZO (CTLLZO) provides 3D interconnected chain structure, which is favorable for long Li+ transfer channel, providing high Li+ conductivity and enhanced stability. CPEs with LLZO prepared using other methods were also compared with CTLLZO to understand the influence of LLZO particle morphology on the ionic conductivity of solid-state electrolyte. |
