摘要
我们报告了一种通过溶液浇铸法制备的阿塔蓬石改性聚环氧乙烷(PEO)基固态复合电解质薄膜。研究发现,电解质膜(0.9PEO-0.1PVDF-LiClO4-3% attapulgite)中最佳的 3% attapulgite 和 10% PVDF 在室温下具有 2.55×10-4 S cm-1 的高离子电导率和 2.25×10-11 S cm-1 的电子电导率。此外,LiFePO4/0.85PEO-0.15PVDF-LiClO4-3% attapulgite/Li 全固态电池的初始放电容量为 120 mAh g-1,即使在 0.1 C 下循环 10 次后,全固态电池的比容量值仍高于 60 mAh g-1。
Attapulgite Enhanced Polyethylene Oxide-Polyvinylidene Difluoride-Based Composite Solid-State Electrolyte for All Solid State Li-Ion Batteries
We report an attapulgite-modified poly(ethylene oxide) (PEO) based solid-state composite electrolyte film by solution casting method. The influence of attapulgite and polyvinylidene difluoride (PVDF) on the electrical properties of PEO-based solid-state electrolytes was investigated
and it is found that an optimal 3% attapulgite and 10% PVDF in the electrolyte film (0.9PEO-0.1PVDF-LiClO4-3% attapulgite) exhibited a high ionic conductivity of 2.55×10−4 S cm−1 at room temperature and electronic conductivity of 2.25×10−11
S cm−1. Furthermore, The LiFePO4/0.85PEO-0.15PVDF-LiClO4-3% attapulgite/Li all-solid battery exhibited a promising initial discharge capacity of 120 mAh g−1, and even after 10 cycles at 0.1 C, the specific capacity values of the all-solid
battery remained above 60 mAh g−1.
